formatting X-axis labels

I have a graph with X-axis labels coming from an Excel cell range
All data labels have same format (fontsize and color)
Is it possible to format individual labels for example label1 in bold and label4 in red ?

Hi Roland,

I might very well be wrong, but I don't think it's possible. However, I'm quite happy to be corrected by our more enlightened contributors.
