Hi HQO,
The defaul chart setting is that if a user clicks a chart with the left mouse button and drags to the right and bottom direction, when the button is released the chart is zoomed. To prevent this behaviour you can use the code above or also block it at the chart editor.

I think I didn't explain it correctly. Even I am using the zoom property. The problem comes when i draw some lines using Steema.TeeChart.Tools.DrawLine method. The lines gets displayed but it becomes movable by user and also user can draw other lines in the graph. I want to avoid this. Please let me know if u have any solution

Hi HQO,
Ah, ok
! Now I understood what you want. Then you can disable lines drawing and being selected using:
Code: Select all
this.drawLine1.EnableDraw=false;
this.drawLine1.EnableSelect=false;
