Dear Xara...

I like the versatility of the Bar & Column Charts.
I particularly like that I can add text before and after a value and the calculation on changing the bar value, by drag or entry, still works.

Could you include a logarithmic scale?
Can you colour code the Bar height and Vertical bar spacing other than blue?
I find these often disappear if the Zoom is at 100% or less.

There is a degenerate behaviour.
You can set a bar to zero with no problem. If you reduce this further the entire bar disappears, label, value and all.
I find I have to Zoom to 250% to reveal the Bar value control.

I would like negative numbers to be possible with the origin shifted accordingly.
