Changing individual axis labels on the same axis (vba?)

[sikey]

Hi,

I have a stacked bar chart with about 30 horizontal bars and a corresponding y-axis. Half of these bars are previous data values for comparison. I would like to format the y-axis labels that start with "previous" in italics (or a different colour).

In addition, if possible, I would like to have the bars which corresponde to the axis labels in italics thinner than the other bars.

Any help would be much appreciated. (Preference would be a way to do this with vba if possible).

Many thanks,

sikey
