I am currently evaluating for my companys UX Team what funktionality can be covered with the CanvasJS and there are two features that they asked for, that i can not find from the demos and docu right away.
1) Being able to add a vertical line at a specific y axis value. The graph will display “today/now” in the center and left and right of it, the values (real values to left, expected values in the Futuer to the right).
2) Is there an easy way to define the axis starting or positioning a certain value in the center ?
3) Always showing a “ballon with text” at specific position.
