I have been trying to create a graph in .net C# with the library: https://v0.lvcharts.com/
I have quite a few different series on my graph and all with different points per x value. As seen below this is the current tooltip on hover.
What i need is to only display the X value: 00:07 & the Series 'Measured Temperature'. I do not want to show any of these other series on my tooltip. If i use the SelectionMode.OnlySender it does not show the X value: 00:07 which is quite important since graphs can be over 24 hours long..... Because otherwise it would be quite tricky to find out at which time you are specifically looking...
Does anyone know how to only show 1 series with Y&X value? Not any other series...
The project is made in WinForms c# .NET
You need to change the IsVisible property in your element of graph collection:
SeriesCollection[i].IsVisible = false;
i - is the index of the element in the collection
If it looked like creating a pre-hidden element:
SeriesCollection = new SeriesCollection
{
new LineSeries
{
Title = "Series 1",
Values = new ChartValues<double> { 4, 6, 5, 2 ,4 }
IsVisible= false; // this one
}
};
Or is your goal to leave all the graphics in place, but only hide all the fields in the ToolTip except the one you hovered over?

I've researched and can't seem to find if adding Data Labels to Dataviz charts is possible. I haven't seen an example that actually shows them. Is this something that is even possible ?
An example of adding a Y-axis label:
var datapoint = new Bunifu.DataViz.DataPoint(Bunifu.DataViz.BunifuDataViz._type.Bunifu_line);
datapoint.addLabely("SUN", r.Next(0, 100).ToString());
I'm in the middle of creating a piece of software for the company that I have internship at, now I'm having some trouble iterating through 2 dynamic lists.
The first list is a list of grids (WPF) and the other one is list of Column Definitions (WPF) I'd like to add 3 columns to each grid in the GridList, but I'm not quite sure on how I'd go about doing so.
If you need some code examples then I'll happily add them, but I don't see it nessecary for this kind of question.
When I say Dynamic List, I mean a list that doesn't have a set size, so in my case it depends on which day it is.
Create an Object of list, and add your grids to it:
var grids = new List<Grid>
{
new Grid(),
new Grid(),
new Grid()
};
Iterate through the grids and add what you want to them:
foreach (var grid in grids)
{
grid.ColumnDefinitions.Add(new ColumnDefinition());
}
I have a wpf application. Upon a user request I create a datagrid of certain columns for all the data from a database. I need to print this information. Preferably I would like to print all odd pages first and then all even pages with a header and footer. I have the following code so far but when I print I only get what I see on the screen. I am sure it is pdPrintDialog.PrintVisual statement. I am assuming I need to use pdPrintDialog.PrintDocument. But I don't know to convert the datagrid or datagrid.itemssource to Documents.DocumentPaginator. I can not find how to do this anywhere. Please help!
System.Windows.Controls.PrintDialog pdPrintDialog = new System.Windows.Controls.PrintDialog();
if ((bool)pdPrintDialog.ShowDialog().GetValueOrDefault())
{
Size pntPageSize = new Size(pdPrintDialog.PrintableAreaWidth, pdPrintDialog.PrintableAreaHeight);
dgPWLCGrid.Measure(pntPageSize);
dgPWLCGrid.Arrange(new Rect(5, 5, pntPageSize.Width, pntPageSize.Height));
pdPrintDialog.PrintVisual(dgPWLCGrid, "North Berwick Food Pantry Client Info");
}
I have a DataGridView that displays information that is read from a txt file. My aim is to create a line graph for this data which displays DateTime for the X axis.
My aim is to create the graph so it shows the information from the Gridview onto the graph. The user can then select points on the graph that then show them specific info from that part of the data for example a row.
I am not sure which API to use for this:
I have tried using internal Chart functions for Visual Studio but I can not interact the selectable part onto the graphs I created.
If anyone has any advice on how to do this would be great.
Your question seems to have several parts. I'll try to help with each..
The last part in your question is solved like this:
Assuming you have a Chart with the DataPoints set and showing the line, you can use this:
Series S = chart1.Series[0]; // short reference
S.ToolTip = "#VALX{#.##}" + " : " + "#VALY1{#.##}";
to display the x- and y-values as tooltips in a format you like.
See MSDN for a full list of keywords to use in referring to the DataPoints
If you want to display data that are not part of the DataPoint's data you can instead create individual ToolTips for each DataPoint when you add it:
double dx = yourXValue;
double dy = yourYValue;
DataPoint dp = new DataPoint(dx, dy);
dp.ToolTip = yourToolTip;
S.Points.Add(dp);
You will have to create the ToolTip readily formatted for each DataPoint!
If other parts are still open, please say so!
Though I have values on the asp graph as attached, what I need is a different value to be shown on each bar.
For example instead of 5 on the bar graph I need to display 50 (instead of the label that displays 5).
What I would like to know is what property like the one below should i use in order to manipulate the label shown on each bar.
Chart1.ChartAreas[0].AxisX.TitleFont = new Font("Times New Roman", 11f);
Thanks in advance.
The value for the label can be set as below:
Chart1.Series["Series1"].Points[counter].Label = "2";
