Hi Erel
I'm using your module charts.bas but i can not remove the bars
thet before i have displayed, i clear all drastically with RemoveAllNodes.
Another questions:
I attached a picture where the name on the x axis is truncated, I can not increase the space.
how can I do?
Thanks for your patience

The x axis titles are drawn in line #157: Canvas.DrawTextRotated(p.x, x, GI.originY + 12dip, fx.DefaultFont(12), G.AxisColor, "RIGHT", -45)

You can modify it to increase the size.

You cannot remove the bars without redrawing the graph. When you call Charts.DrawBarsChart it firsts clears the whole canvas.

Thanks Erel for your suggestion
but I would like more space for more characters without changing the font size.
It's possible?

Yes. But you will first need to understand how the grid is drawn. You can then make the grid a bit smaller and have more space for the titles.

With the same dimension as in charts.bas (after I program the size of the bars and the axis scale).
Thanks
