Hi,
I need to draw two constant lines in report chart. The chart is in a databand and I need to set the axis value of constant lines at run time. Could you please let me know how can I achieve it?

Hello,
You can use the following code:
Code: Select all
StiChart chart = report.GetComponents()["Chart1"] as StiChart;
Stimulsoft.Report.Chart.StiConstantLines constLine = new Stimulsoft.Report.Chart.StiConstantLines();
constLine.AxisValue = "10";
constLine.LineColor = System.Drawing.Color.Black;
constLine.Text = "Constant Line 1";
chart.ConstantLines.Clear();
chart.ConstantLines.AddRange(new Stimulsoft.Report.Chart.IStiConstantLines[] {
constLine});
Thank you.

Hi Aleksey,
Thanks for your reply.
But my chart is in a databand and Constant Line Axis value may change from one chart to next chart.
If the chart is not in the databand, we can use the above code.
Thank you

Hello.
Then you should set the Constant Line in the Before Print event of the Chart.
Thank you.

Hi Aleksey,
I am not sure how to add constant lines in before print event.
I have already added below code for setting the text after property of Y axis
this.Chart2_Area.YAxis.Labels.TextAfter =" " + C_Data.Unit;
I have tried to create constant lines in the before print event by following the syntax of the above code. But it is not working.
Could you please let me know the code to add constant lines in Before print event?
Many Thanks.

Hello,
Thank you very much.. It works good now.
But the constant line "text" drawn vertically and it is in the right side of the Y axis. Is there any way to draw the "Text" value horizontally and place it in the left side of the Y axis?
I have attached the current chart image and expected chart image with this mail.
Many Thanks

Hello.
Unfortunately, it's impossible to show labels this way now.
Thank you.
