Hi Rs,

You may use Axis.setReverse. For example, in VB/VBScript:

Call c.yAxis().setReverse()

Hope this can help.

This does but it also makes bar charts to start from top and not from bottom.
I want to only reverse values on y -axis and keep chart same.

Hi Rs,

By default, the bar starts from zero (or the direction that contains zero), and "grow" to the data value. If your axis is reversed, and your data are positive, then the zero direction is at the top, and the bar will start from the top. If your data are negative, the bar will start from the bottom.

If you want the bar to start from the bottom (from the direction of positive infinity), you may use BarLayer.setBaseLine. For example (in VB/VBScript):

Set layer = c.addBarLayer(data)
Call layer.setBaseLine(1E100)

Hope this can help.
