I'm going to be starting a project where the interface will present the user with a number of line graphs drawn in the same grid. (I'm using the word grid loosely.)
I need to be able to display the lines in different colors (or styles such as solid, dotted, dashed, etc) with plotted point represented differently for each line - circle, square, triangle, etc.
I probably need tool tips when the mouse is held over a plotted point.
The user will need to be able to drag points to a new position.
The tool needs to have an object model that will allow me to quickly sum the Y values of all points at each X coordinate.
Any recommendations, suggestions for a control that will support this behavior. Thanks
