Hello,
I was wondering whether it would be possible to use custom code to allow survey takers to draw a line on the image in a heatmap question. So instead of clicking to form individual dots, they would be able to click and drag to draw a straight line. Or maybe they could click on two points, and the custom code would connect the two points to form a line. The recorded answer to this question would ideally be the x and y coordinates of the two endpoints of the line.
Thank you in advance for your help!
