We really do not know what to suggest It's not so complicated - may I try? )) You must add to every tool flag like UsePixelCoordinates. When you (re)draw chart or when it resized, you definitely know its real width and height in pixels (as I hope). So, on redraw or resize event you simply recalculates this "pixel" coordinates to your current "percentage scale coordinates" with simplest formula: x = x / window(chart)width * 150 y = y / window(chart)height * 100 You will get new tools coordinates which is already familiar to your drawing engine - no any modification to last one are not required. The only small code injection before positioning any drawing. Below is example in abstract language: current code: Place(tool, tool.x, tool.y) changed to: x = tool.x; y = tool.y; if ( UsePixelCoordinates ) { x = x / window(chart)width * 150 y = y / window(chart)height * 100 } Place(tool, x, y) or this one: if ( UsePixelCoordinates ) { x = x / window(chart)width * 150 y = y / window(chart)height * 100 Place(tool, x, y) } else Place(tool, tool.x, tool.y) "That's all folks" as it seems to me ;) What do you think about this idea?
