Hi Volodya,
Thanks for your interest in Syncfusion product.
I have created a simple sample to meet your requirement. please find the uploaded sample.
1. We donot have support to bind both X and Y value to the Label, Please create the incident in our Direct trac so that we will provide you the custom patch with this support.
2. We can get the X and Y value in the ToolTip by customizing the ToolTip using the Template property. please refer to the attached sample.
3. Performance can be increased by using the BeginInit() and EndInit() methods in the ChartArea.
code snippet:
Chart1.Areas[0].BeginInit();
AddDataToSeries();
Chart1.Areas[0].Series[0].DataSource = coll;
Chart1.Areas[0].Series[0].BindingPathX = "TaskName";
Chart1.Areas[0].Series[0].BindingPathsY = new List
{ "Y" };
Chart1.Areas[0].EndInit();
4.Setting the interval as 1 will take time to render the axis, gridlines and labels for each DataPoints so I have set the Interval as 20 for 100 DataPoints.
5. ToolTip can be added in the Zoomed ChartArea, please refer to the sample.
Let me know, if you have any queries.
Regards,
Sujitha S
