X and Y Error bar
At the moment X axis error bar and y axis errorbar( using inverted option) are available.
It would be great to add the ability to have them both together in the same chart.

I've created a plugin that enables X and Y error bars:
Sorry about the mix up of x and y axis.
Technically the current implementation only works in the Y direction, as in an inverted chart the Y and X axes swap places. So the feature request would be to add X ranges to the current implementation.
