How to make graphics (Shape, animation) in c#

How to make a circle with text inside ?? then move it from one location to another, and then access it later (to delete it).
I want to make something like this

Your question is really very broad and you got a few nice links you should study to learn all about GDI+ drawing.
But if taken literally there is a slightly exotic alternative which puts the burdon of most chores onto the Chart control from DataVisualization.Charting.
You can create EllipseAnnotations and add them to a Chart control.
Disable the Axes and clear the Legends and then use code like this to add a moveable circle wit thext inside:
EllipseAnnotation ea = new EllipseAnnotation();
ea.X = 11; // put at..
ea.Y = 11; // 11% of the chart's area
ea.AllowMoving = true;
ea.BackColor = Color.BlanchedAlmond;
ea.Text = (chart1.Annotations.Count + 1) + "";
chart1.Annotations.Add(ea);
Note that there are quite a few annotation types available. which allow you to add Rectangles, Images, Polygons, Lines and pure Text.
And another pro is that saving or loading the graphics takes only one line each, as you can serialize a Chart out of the box!

To draw shapes follow here.Also you need a complete tut,you can follow here
Some insight is here:
To draw a simple shape at design time Drag the OvalShape or
RectangleShape control from the Visual Basic PowerPacks tab (to
install, see Visual Basic Power Packs Controls)in the Toolbox to a
form or container control.
Drag the sizing and move handles to size and position the shape. You
can also size and position the shape by changing the Size and Position
properties in the Properties window To create a rectangle with rounded
corners, select the CornerRadius property in the Properties window
and set it to a value that is greater than 0. In the Properties
window, optionally set additional properties to change the appearance
of the shape. To draw a simple shape at run time On the Project
menu, click Add Reference. In the Add Reference dialog box, select
Microsoft.VisualBasic.PowerPacks.VS, and then click OK. In the Code
Editor, add an Imports or using statement at the top of the module:
using Microsoft.VisualBasic.PowerPacks; Add the following code in an Event procedure:
ShapeContainer canvas = new ShapeContainer();
// To draw an oval, substitute
// OvalShape for RectangleShape.
RectangleShape theShape = new RectangleShape();
// Set the form as the parent of the ShapeContainer.
canvas.Parent = this;
// Set the ShapeContainer as the parent of the Shape.
theShape.Parent = canvas;
// Set the size of the shape.
theShape.Size = new System.Drawing.Size(200, 300);
// Set the location of the shape.
theShape.Location = new System.Drawing.Point(100, 100);
// To draw a rounded rectangle, add the following code:
theShape.CornerRadius = 12;
Customizing Shapes When you use the default settings, the OvalShape and RectangleShape controls are
displayed with a solid black border that is one pixel wide and a
transparent background. You can change the width, style, and color of
the border by setting properties. Additional properties enable you to
change the background of a shape to a solid color, a pattern, a
gradient fill, or an image. Before you change the background of a
shape, you should know how several of the properties interact. The
BackColor property setting has no effect unless the BackStyle property
is set to Opaque. If the FillStyle property is set to Solid, the
FillColor overrides the BackColor. If the FillStyle property is set to
a pattern value such as Horizontal or Vertical, the pattern will be
displayed in the FillColor. The background will be displayed in the
BackColor, provided that the BackStyle property is set to Opaque. In
order to display a gradient fill, the FillStyle property must be set
to Solid and the FillGradientStyle property must be set to a value
other than None. Setting the BackgroundImage property to an image
overrides all other background settings.

Bars in Bar graph are of different size

I am drawing a bar chart and I saw some of them have different width than others.
I tried changing PointWidth and PixelPointWidth properties. But of no use. Here is the graph I got :
The only configure I done is barChart1.Series["DeltaE"]["PointWidth"] = (0.6).ToString();

You may have too many data and the chart is too small. Try delete some data or make the chart bigger.
I made an example. I created a c# project, put a chart in the form, randomly add some data and run the program.
When the chart is big enough, it looks well.
When the chart is smaller, not all the columns are the same width.

How to control winform mschart legend text alignment c#?

How does one set the alignment of text within a chart legend object? I've tried using:
myChartName.Legends["mySeriesName"].Alignment = stringAlignment.Near
With no effect. I've also tried to create custom legend items, again resulting in no effect. Text is ALWAYS centered (along with the series marker) in the legend "box". The only text I have been able to align is the title, but I don't need titles in my application.
My research to date says the legend object is basically a table with (by default) two cells. If that is the case there should be a way to access those cells and manipulate them as table cells. So, what gives? Why can't I access the text alignment properties of the legend object? Clearly, there is something I'm missing, but for the life of me I can't seem to figure this out. Quite frustrating.

Problem solved. The CustomItem approach wasn't working either, so I tried using the LegendCellColumn Class.
I changed the LegendStyle from Column to Row, then added two CellColumns, one for the series symbol and one for the legend text. Set the alignment, margins, and column widths (that turned out to be the trick), and voila; a legend that looks like I want. Here's the code for anyone with a similar issue.
chartSel.Legends[ySeries.Name].CellColumns.Add(new LegendCellColumn("", LegendCellColumnType.SeriesSymbol, ""));
chartSel.Legends[ySeries.Name].CellColumns[0].Alignment = ContentAlignment.TopLeft;
chartSel.Legends[ySeries.Name].CellColumns[0].Margins = new System.Windows.Forms.DataVisualization.Charting.Margins(0, 0, 1, 1);
chartSel.Legends[ySeries.Name].CellColumns[0].MinimumWidth = 250;
chartSel.Legends[ySeries.Name].CellColumns[0].MaximumWidth = 250;
chartSel.Legends[ySeries.Name].CellColumns.Add(new LegendCellColumn("", LegendCellColumnType.Text, ySeries.Name));
chartSel.Legends[ySeries.Name].CellColumns[1].Alignment = ContentAlignment.MiddleLeft;
chartSel.Legends[ySeries.Name].CellColumns[1].Margins = new System.Windows.Forms.DataVisualization.Charting.Margins(0, 0, 1, 1);
chartSel.Legends[ySeries.Name].CellColumns[1].MinimumWidth = 1500;
chartSel.Legends[ySeries.Name].CellColumns[1].MaximumWidth = 1500;
It's probably not the most efficient way to do it, but it works. Technically, the legend symbol and text are still centered in the object, but because I'm forcing the widths of the two columns it has the appearance of being left-justified.
Hopefully, this may help another newbie like me avoid days of consternation.

My understanding is that Legend alignment relates to the Docking property, not really how the text is aligned within the legend. So setting Alignment to Near means positioning the legend box near the Docking direction.
It is quite hard to explain this textually. The MS Chart Samples have a subsection named Chart features -> Legends -> Style and Auto Positioning which will help you play with those two properties and understand how they are meant to work.
For inner legend alignment, you may need to use Legend.CustomItems and define LegendCell individually.
chart.Legends["Default"].CustomItems.Clear();
chart.Legends["Default"].CustomItems.Add(new LegendItem("LegendItem", Color.Red, ""));
chart.Legends["Default"].CustomItems[0].Cells.Add(new LegendCell(LegendCellType.Text, "My text", ContentAlignment.MiddleLeft));
This is described inside the Chart features -> Legends -> Legend Cells section of the samples.

While continuing to try to figure this out I stumbled on this tidbit of info from the following MSDN library page:
http://msdn.microsoft.com/en-us/library/dd456711(v=vs.100).aspx
"NOTE: You cannot adjust the individual legend items and cells in the Chart.Legends collection. To adjust them, use custom legend items."
So, back to the CustomItem route. I've got this code gleaned from several sources (including you, Dominique, thanks):
chartSel.Legends.Add(ySeries.Name);
chartSel.Series[ySeries.Name].IsVisibleInLegend = false;
chartSel.Legends[ySeries.Name].CustomItems.Clear();
LegendItem li = new LegendItem();
li.ImageStyle = LegendImageStyle.Line;
li.Cells.Add(LegendCellType.SeriesSymbol, "", ContentAlignment.TopLeft);
li.Cells[0].BackColor = Color.CornflowerBlue; //color is only to see the cell bounds
li.Cells.Add(LegendCellType.Text, ySeries.Name, ContentAlignment.TopLeft);
li.Cells[1].BackColor = Color.Aquamarine; //color is only to see the cell bounds
chartSel.Legends[ySeries.Name].CustomItems.Add(li);
From what I can find it should work, but it doesn't. It results in a legend object with two cells; the first is empty and the second has left-justified text. I tried to post an image of it, but the system says I'm not yet worthy.
Why there is no line for the series symbol is also a mystery, but that's another problem to solve. The text justification issue is my main concern at the moment. It looks like the text within the cells is left-justified as desired, but the cells themselves are centered in the legend object; not what I wanted. I want those cells to be left-justified in the object too, so the first cell is against the left edge of the legend object.
Ideas?

Drawing a chart in WPF C# design questions

I had a project a month ago where I drew a stock chart in an application using Windows Forms. I did this by creating a bitmap that would stretch to the dimensions of the window. This would allow my chart to resize with the window.
I am now expanding the project using WPF. I have been trying to work on my design for the project, but I cant seem to get any idea on the best way to do the same chart. I have looked at canvases, grids, and a few other controls. I thought I was on the right track with the canvas, but when I would resize the window, my drawing would stay in the same spot. I guess the point of my post tonight is to get some ideas to help me brainstorm a design for my project.
All advice and questions are appreciated.
Thanks,
Joseph

(Realizing this addresses at best a subset of this fairly old question, since it's only one chart type...)
Just fwiw, creating a bar graph in a Grid as Ed suggests is pretty straightforward. Here's a quick and dirty version:
Add a Grid to your Window's XAML. Just for testing, here's one that fills the Window entirely.
<Grid>
<Grid
Name="myGrid"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Width="auto"
Height="auto"
Margin="10,10,10,10"
/>
</Grid>
Now insert these two utility functions somewhere in your project. These provide simple, single-color columns and unstyled, but centered, label text for the x-axis.
I think the only nasty kludge is the maxHeight in the _placeSingleColorColumn call.
Worth mentioning: I don't have labels for the y-axis in this quick & dirty version.
private void _placeSingleColorColumn(Grid grid, Color color, int height, int colNum, int maxHeight)
{
Brush brush = new SolidColorBrush(color);
Rectangle rect = new Rectangle();
rect.Fill = brush;
Grid.SetColumn(rect, colNum);
Grid.SetRow(rect, maxHeight - height);
Grid.SetRowSpan(rect, height);
grid.Children.Add(rect);
}
private void _createLabels(Grid grid, string[] labels)
{
RowDefinition rowDefnLabels = new RowDefinition();
grid.RowDefinitions.Add(rowDefnLabels);
for (int i = 0; i < labels.Length; i++)
{
TextBlock block = new TextBlock();
block.Text = labels[i];
block.HorizontalAlignment = System.Windows.HorizontalAlignment.Center;
Grid.SetColumn(block, i);
Grid.SetRow(block, grid.RowDefinitions.Count);
grid.Children.Add(block);
}
}
That's really it. Here's some insanely quickly and dirty example code to create a 10 by 10 grid with some sample data.
public void createGrid10x10()
{
Random random = new Random();
for (int i=0; i<10; i++)
{
ColumnDefinition colDef = new ColumnDefinition();
myGrid.ColumnDefinitions.Add(colDef);
RowDefinition rowDef = new RowDefinition();
myGrid.RowDefinitions.Add(rowDef);
Color color = i % 2 == 0 ? Colors.Red : Colors.Blue;
_placeSingleColorColumn(this.myGrid, color, random.Next(1,11), i, 10);
}
string[] aLabels = "Dogs,Cats,Birds,Snakes,Rabbits,Hamsters,Horses,Rats,Bats,Unicorns".Split(',');
_createLabels(this.myGrid, aLabels);
}
Add one line to your MainWindow constructor, and you're done, afaict.
public MainWindow()
{
InitializeComponent();
this.createGrid10x10();
}
Now you've got a bar graph that'll resize and stay proportional as the window is resized, etc.
Adding more labels (bar values on top, y-axis labels, etc) should be pretty straightforward if you understand the above. Just throw in another column and/or row, create your TextBlocks, and place them in the right locations.

Try using a DockPanel and set LastChildFill to true. Then make your control the last child of the DockPanel.

Funny: I am just making the same thing!
I already developed a chart control, plenty of features. Now I need to renew and extend it with some other function. However, my deal is manage even 100k of points on a single chart, but keeping a good performance on a normal pc. By resizing the window will scale the chart, but not the text eventually placed on it. Also consider that I need a real-time rendering of the data incoming at least 0.5 sec.
All that has been resolved using the old-style bitmap creation, then placing it as a normal image on any wpf control. There are several limitation because there's no "living" objects as in the wpf you have, but the rendering performance is really huge compared to the wpf primitives.
So, unless you have charts with max 100 points to manage, I strongly recommend the hybrid approach. Anyway, it's a very hard task!
Cheers

I am assuming you want to draw your own chart rather than using WPF charts.
Canvas is not usually a good thing to use in WPF because it fixes objects at a specific location and size, exactly as you've seen (though I suppose you could use a Canvas with a ScaleTransform). Grid will take the size of its container, so putting a Grid into a window will make the Grid resize with the window (unless you specify a fixed Width and Height for the Grid). StackPanel will stack things and will attempt to take the minimum size of its content, so that's probably not what you want to use here.
Creating a chart layout inside a panel like a Grid isn't completely simple. If you are doing a bar chart, you could create a Column in the Grid for each bar, assign a percentage width such as star; and the columns would get larger as your Grid expanded with the window. You can use a similar trick by making each Bar a Grid, setting two columns in the Grid, and setting a third level of Grid inside the lowest column, then using percentages for the column heights (e.g., 90star and 10star for 90%, 10% heights). The bars would then grow taller as the window grows taller. You could reserve a Grid row below the bars for labels, and center them under the bars.
Line charts are trickier. You would probably want to create a GeometryDrawing of line segments, and then use a ScaleTransform bound to the window size to make it shrink and grow.
There are a lot of possibilities with WPF, but you'll need to do a bit of leaning and studying first. A book such as Adam Nathan's "Windows Presentation Foundation Unleashed" would quickly give you a lot of knowledge of WPF layout and how to proceed.
Edit: You could also use an empty panel and use its DrawingContext to draw lines, rectangles, text, ellipses, etc. at points you calculated from the current window size.

Draw a Grid over a Picturebox in c#

I am trying to make a tool in c# which allows the user to put a grid on the screen on a picturebox. At the moment i don't know how to do this, so when a button is clicked, the picturebox comes up with a grid. It needs to be a grid which is spaced out enough that users can find out locations of objects on the picture in the picturebox. Help with what code i can use to do this would be very helpful as i was going to use ControlPaint.DrawGrid but not sure of the values i need to put in it to get my desired effect?
Thanks

Form the Documentation od controlpaint.Drawgrid,
I suppose you need to decide on the cell size in x- amd y-direction and pass this as a size parameter to Drawgrid:
public static void DrawGrid(
Graphics graphics,
Rectangle area,
Size pixelsBetweenDots,
Color backColor
)
for example, a 100*200 pixels square grid would be generated by
setting graphcis to the context you want to draw upon,
Setting area to the top left right and bottom parameters of your image
setting size.x to 100 and size.y to 200
setting color to any color you like.
Update
Something like this should do.
Rectangle myRect = new System.drawings.Rectangle();
myRect.Location := new System.Drawing.Point(0,0);
myRect.Height = 50;
myRect.Width = 50;
Drawgrid(FromImage(yourImage), mygrid , yourImage.Size, System.Drawing.Color.Black);
Disclaimer: i don't develope in c#, so above code is not tested for anything. I just picked stuff from the documentation (msdn).
