Formatting of 6 charts to increase the font of chart text.

I have 6 charts that need formatting so that the font size of the text increases. I think that this is a simple job in InDesign or something similar. I can send you the charts as they stand (so that you can understand the problem - the font is to small when the charts are pasted in my word report. I have the data and charts in an excel file. The only thing I need changing is the font and making sure the charts look neat and in proportion. It's probably 1 hours work? Many thanks, Jane
