I have an annoying little problem.
i am wanting to display data in a chart on my web form.

The X axis is the Op Number
The Y axis is Competence (1 to 5)

Say the Op Numbers for a certain stage are 10 30 55 80 the X axis puts an interval in between each, so the X axis ends up looking a mess and the bars are rather thin.

Is there a way to either:

a) Add a prefix 'Op' to the Op Numbers in the dataset (I have another chart with BM111, BM134 etc on the X axis and there is no intervals between each)


b) Stop the X axis putting intervals in at all so it just displays 10 30 55 etc..
not 10 15 20 25 30 35......

Thanks for taking the time to look, and for any help!!!!
