I have a question regarding bar charts.
On this type of chart I need to be able to modify the height of each bar (like on a usual bar charts) but also the width of each bar (this is less usual...).
So all those bars need to be modifiable in height and width and have to be stuck together (no space between them).
Is it possible to achieve that with your library ? Do I need to use a special chart ? in 2D or 3D?
Thank you in advance for your help,
