The Multiple Stock Performance is an excellent tool. However, after the results are displayed, its very difficult to discern which of the graphs pertains to which of the selected stocks and if a person is even slightly challenged with distinguishing colours its quite an impossible task. The following options are suggested:
- The graphs be made selectable and their names get highlighted.
- Alternatively, when the mouse is taken close to a graph their names appear as a tooltip.
In addition in case the display period could be dynamically changed it would help.
