I am trying to create a chart showing numbers (Y axis) and date (X axis). Using default setting, horizontal axis (X axis) is filled with overlapped/unreadable texts (for dates). I would like to make this in the same way as in the sample diagrams at the following page. https://world.mendix.com/display/refguide4/Report+Chart How can I make date (e.g. 5/20/2013) shown in vertical direction (from bottom to top)?
I don't think you can.
The chart is created via XML and a swf file there seems to no option to change the direction of the labels on the x axis.
What you could do is change from a vertical bar to a horizontal bar chart (e.g.) then the dates are displayed nicely, but it surely depends on what you are showing your end-users.
