Hi,
Please can you tell me how I can alter the x axis to go from 200 to 10e10?
Many thanks

I would use the semilogx function to plot your data.

Hi,
Thank you - I have been using this function, but seem to be having problems altering the axis limits. Do you have any idea what I could try?
Many thanks

My pleasure.
Explore the Axes Properties of your plot and experiment with them to see what works for you.

Are you sure you mean 10e10 and not 1e10? Otherwise, setting the axes is quite straight forward:
y = linspace(200, 10e10);
semilogy(y)
axis([1, 100, 200, 10e10])
