Helder,

what you suggest is a clever way to get around the problem. However, I understand that BARCOORDS is an output parameter, rather than an input one, hence I don't see how you can use BARCOORDS to determine the placement of the bars on the X axis.

Even in the two examples you suggested, there is always one tick below the bar, while I really would love the bar to be placed in between two ticks. And, I cannot draw the bars one by one. That's my real issue.

Cheers,
Federico
