I have an area chart. As the user mouses around over it, I'd like a hirzontal and vertical "crosshair" (one horiz, one vert gridline, sort of) to track the mouse pointer.
I see the annotationelements, and am already using it for my gridlines. I'm wondering if anyone has ideas of how to implement the crosshair? I'm guessing a canvas that I can use the drawing API on to draw the lines as the mouseMoves. But how to tie the position of the mouse over JUST the chart area showing the actual data (not over the axes labels, etc) to the X and Y to draw the lines? And how to get it to work in the annotationElements array? I'm assuming I need to make whatever I create a ChartElement, but I haven't ever actually cracked open the existing objects and tried to tie into them at such a low level. If anyone has any thoughts or guidance, even just for general ways to get into the source code and create a new class from them, I'd appreciate it. Thanks! ------------------------ Yahoo!
