I'd like to see some improvements to the way graphs display.
1) Allow control to format the Y Axis (eg. set Min/Max, ability to edit Label)
2) Make bar columns line up with horizontal axis lines.
In the example below, the graph is used to chart student course results. A maximum score is 8, however the graph displays 10 on the Axis so students are confused thinking they can get a greater score. Also, in the example the bar column with a score of 8, doesn't line up with the 8 in the Y Axis.
It would also be nice to be able to have control over graph colours (ideally using formula), not essential but definitely could be helpful in creating better visual display.
