Remove Overlay Line

[henk_kempen]

Hi everyone,

I created a circle, and every time you press a button next, I overlay a different line on the circle,  I want when you push the button, that a new line appear (that works fine) but i need the previous line dissappear every time you push the button, so there is one line at the time. How can you remove the previous line when the next line appear?

Best regards,

Henk

Please explain how you are drawing circle and doing overlay. If possible please attach the code (in 2011 version) for a better solution.

I put the start and end point into IMAQ overlay line,

Tnx,

Henk
