Hi everyone, apologize for propably bad english.
Can anyone give me advise, where should I read about the interaction between chart and mouse.
Heres exactly what I need,for example: some kind of button on the chart. So when I click it, it's becomes possible to put 4 "dots" with mouse click, and after that these 4 dots are connecting together in to quadrangle.
Also, the coordinates (Time, Price) of the dots are used in some calculations, so I need them...Any suggestions?
...seemed like a fun little warm up exercise.
I tried to draw a face.
That's close to what I need, but I didnt understand anything in code =(
