I want to display some values on graphic using a Chart in C#. I am using the following code
graphics.graphic1.Series[0].Points.AddXY(1, 14);
graphics.graphic1.Series[0].Points.AddXY(4, 0);
graphics.graphic1.Series[0].Points.AddXY(12, 4);
graphics.graphic1.Series[0].Points[0].AxisLabel = "lll";
graphics.graphic1.Series[0].Points[1].AxisLabel = "bbb";
graphics.graphic1.Series[0].Points[2].AxisLabel = "ccc";
to set some point values and some text on the X axis for each point. The problem is that the text is not shown.
What should I do in order to display the text on X axis beneath each point?
In Passing value to another class
you can find a complete working example of a chart using OxyPlot.WPF. If you have not gone too far with your app (which seems to be in WinForms), consider switching to WPF, it will be worth your while. Specifically, the result in that example is that without doing any special effort you get a chart with automated zoom as well as manual zoom (mouse wheel) on X and on Y.
switching to a DateTime x-Axis is as simple as changing the type of the axis in the XAML from:
<oxy:LinearAxis Position="Bottom" Title="Curvature (rad/in)" TitleFont="Arial" TitleFontSize="12" TitleColor="Black"/>
to:
<oxy:DateTimeAxis Position="Bottom" Title="Time" TitleFont="Arial" TitleFontSize="12" TitleColor="Black"/>
then when zooming you see your X-Axis automatically changing from Time only at 1 minute resolution to a 10 minute resolution to hourly, and then to date resolution... Magic.
I was really impressed by the results of this (see full example in the link).

In my WinForms project I use the standard Chart control (from the VS toolbox) to display pressure versus time. It must be possible to zoom the graph. This works fine, but the X-axis values in the zoomed graph shows the values in a lot of decimals:
Does anyone have an idea what I can show the values in a better format? For example, in the above graph I would see labels like: 8.00, 10.00, 12.00? I can also live with values like: 7.98, 9.98, 11.98, so with a limited number of decimals.
I've looked in the control designers for the Chart control where I can specify a format string or the number of decimals, but I could not find it.
There is nothing special for this chart. It shows 2 series (not easy to see but you could probably see a blue and a green line). I use for both series the FastLine type of graph. I enabled the zooming by setting IsUserEnabled and IsUSerSelection to true for CursorX and CursorY in the graph designer. As said, this works, but I could not spot a property to customize the format of the values.
Set the LabelStyle.Format property:
chart1.ChartAreas[0].AxisX.LabelStyle.Format = "0.00";
Or
chart1.ChartAreas[0].AxisX.LabelStyle.Format = "{0:0.00}";
I need x axis as time in minutes as 00:00, 00:01, 00:02 ,00:03 ....00:60,01:00,...59:50,...59:59,00:00
if possible to show current date from system date time. and the x axis has to move to left for the whole day. and continue so on.
and y axis 0 to 65324 or may vary accordingly depending on the points it reads but i thik that is the max limit.
How to draw a line chart in wpf with a free source control?
I have tried to worked with WPF Toolkit but not able to find a solution
and now iam using Dynamic Data Display (D3) which is easy but i dont have this type of example.
You can use OxyPlot. It's free, and I've used it in several of my projects.
You can start with the official page, but here's a good example that will set you on the right trail:
line chart + live data.
You'll have to modify the axis a bit, but it's not too dificult.
Here's a screenshot from the above link:
I am trying to construct a chart using the native ASP.NET 4.0 charting control.
I've done nearly everything I wanted to do, but if you look at the following screenshot:
You'll notice that the Y axis labels are all wonky - that is, they are decimals, and they don't fall directly on any of the actual gridlines.
The purpose of my chart is to show a value that will always be between 0 and 16. I need to know the exact value, so I was able to set the gridlines to represent each value, by using this code:
Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Interval = 1;
As you can see, it is showing all lines, 0 to 16. However, the Y axis labels not only do not line up, but aren't even whole values. I would like there to be a label for EACH gridline, and I'd like them to be whole values.
I've done my share of googling, but I mostly find stuff pertaining to turning off the gridlines altogether, which is not what I want.
Any ideas?
can you not just set AxisY.Interval?
chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Interval = 1;
chart1.ChartAreas["ChartArea1"].AxisY.Interval = 1;
I created a test chart quick and got the following:
When I set the interval, I only set the property for the Axis Interval property
chart1.ChartAreas["ChartArea1"].AxisY.Interval = 1;
The default behavior sets the major grid and major tick to this interval unless you have otherwise overridden a property that turns auto off for everything. Microsoft Charting aka Dundas charting (where Microsoft got the code) can be tricky this way.
While I cannot speak for every property within Microsoft Charting, it helps to set the most non-specific property you can find. Only go deeper if you do not get the desired result as going deeper can have unintended consequences by overriding the defaults which generally work quite well.
i.e.:
chart1.ChartAreas["ChartArea1"].AxisY.Interval = 1;
instead of
chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Interval = 1;
Hi I am using Ms chart control in winforms application for displaying values according to dates
I need to change the x-axis label values(Dates) direction horizantal to vertical
I have searched so many properties but i did not find any solution for this.
Any one help me on this problem
Many Thanks ....
As I understand your question - you are asking how to rotate the chart label to display vertically.
You can rotate the x-axis label as follows:
chart1.ChartAreas[0].AxisX.LabelStyle.Angle = -90;
This assumes you have associated your series with the first chart area, which is the default without modification when using the Winforms designer.
The following images shows how the chart would look before the code above is applied, the second image shows how it appears after the code is applied.
Let me know if this is not what you are trying to do and I will post an updated answer.
Before rotation
After Rotation
Edit: Another answer added after my initial post mentions in certain situations it may be important to set chartArea1.AxisX.IsLabelAutoFit = false;
If you have not already done so, get the chart samples from microsoft:
http://archive.msdn.microsoft.com/mschart
Then check the section on Labels
Chart Features > Labels
To answer your question directly, set the angle in LabelStyle, and don't forget to disable autofit
chartArea1.AxisX.IsLabelAutoFit = false;
chartArea1.AxisX.LabelStyle.Angle = 90;
Is it possible to force the display of grid lines on the chart with the dates for the extreme data points?
I've tried almost every configuration of following Chart DateTimeAxis properties: IntervalType, Interval, Minimum and Maximum but I wasn't satisfied with the result.
Setting properties Minimum and Maximum didn't solve the problem.
For instance (IntervalType="Days" , Interval="4" , Minimum="1/1/2010" , Maximum="1/31/2010"):
If I'm lucky I will generate some random data where only one extreme point will have the date with grid line.
Does somebody have an idea how to solve the problem mentioned above?
Edited to add
I added a bounty to this question since I really need a fast solution for this issue.
I am binding a series of specific pairs to my chart and I'd like to display excactly those given DateTime values on the x-axis.
Since these are usually dates like 6/30/11, 6/30/12 and so on, I can't use the Interval/IntervalType properties because adding 1 year or 365 days to 6/30/11 doesn't necessarily result in 6/30/12.
So what I need to do is either disable the "automatic axis label generation" of the DateTime axis or use another axis type.
LinearAxis doesn't work because it expects double values and CategoryAxis is not an option because it displays the axis labels between two tickmarks instead of underneath them.
I am very grateful for any help!
To be perfectly clear, here is what axis labels I need (taken from another chart component):
This is what I get so far with the Silverlight 4 Toolkit:
€: I also opened a thread in the official Silverlight Toolkit Support Forums.
The vertical lines are set where you specify an interval.
There is no vertical line for the data for 1/31/2010 as it does not fall on an interval.
