Hello, I'm trying to display a chart by salesperson, grouped by month, showing the total sales amount. I've attached a photo. I've tried many things without success. Thank you for your time.

I work with WinForms and VB.NET

This code produces a blank image. Am I missing something?

var radChartView1 = new RadChartView();
radChartView1.AreaType = ChartAreaType.Pie;
PieSeries series = new PieSeries();
series.DataPoints.Add(new PieDataPoint(50, "Germany"));
series.DataPoints.Add(new PieDataPoint(70, "United States"));
series.DataPoints.Add(new PieDataPoint(40, "France"));
series.DataPoints.Add(new PieDataPoint(25, "United Kingdom") { Label = "My Label" });
series.ShowLabels = true;
series.DrawLinesToLabels = true;
series.SyncLinesToLabelsColor = true;
radChartView1.ShowSmartLabels = true;
radChartView1.Series.Add(series);
flowLayoutPanel1.Controls.Add(radChartView1);
radChartView1.ChartElement.UpdateLayout();
var name5 = Path.Combine(_outputBasePath, "data05.png");
ThemeResolutionService.AllowAnimations = false;
radChartView1.ExportToImage(name5, radChartView1.Size, ImageFormat.Png);

Hi,

Is it possible to have multiple grids in your chart when working with multiple axes? I only get the grid for the last axis, which is the yellow one in the image below. I would like to have a grid for each axis.

Hello team,

As said in the title, I have a Chart with a cartesian grid visible and working fine. The problem is when I add a series programmatically and the series data is empty (see img.2): my chart displays the new axis as expected with no values since there is no data for the series, but the grid disappears.

Img.1 : Two series with data. The grid is visible fine.

Img.2: Two series with one empty. The grid disappears.

Is there a way to add Tool Tip Text to the legend items that get generated?  I have Tool Tip Text on the Series object, but I would like it on the Legend Items as well. 

Also, one other question, is there a way to customize how the legend shows the value next to the key?  Right now, our legand keys are "ABC 123".  I would like to add a "-" between the KEY and the COUNT value. 

TIA

Hi team ,

I am using Telerik UI for winforms Chartview Drill down charts. I am using line series . I need to get the labels on top of every value( please refer attached screenshot of demo app) but getting object reference not set to an instance of an object .particularly in line  series.ShowLabels = true;  Can you please guide on this?

If I set

Hi team,

I have a scenario where we need to add line series to the chart dynamically from code behind and I need to bind live data (i.e, data changes for every 2 seconds) . I am using Telerik UI for WinForms controls . 

One static line series work perfectly fine using the demo sample. The problem is adding 'n' number of line series and setting data every 2 seconds . In the sample , data is set using a global variable. but we need to achieve the same dynamically 

Can anyone guide on this

Hi!

I have a chart with multiple Y axes, series, and an X axis as DateTimeContinuousAxis.

The thing is my chart is customizable and I should be able to change the series styling from line to column. When I change one of my series to a column, it is not centered with the rest of the series and according to the X-axis (see first img).

See the tooltips that the lines are at the same point (img2) but when I change to column, the column ends at that point, it is not centered.

Any suggestion?

Columns

Linear

Hi

I am playing with the RadRangeSelector. I have associated it to an existing chart. The chart is dynamically filled using data from the database.

In the image here below, the top control is a RadRangeSelector, the bottom control is a RadChartView.

Notice that my bottom chart shows series as stacked. How can I get the RadRangeSelector also showing stacked series?

Also notice that the dates are not inlined between top and bottom. How can the RadRangeSelector be sorted by dates (as my chart is showing)?
