Thread Subject: display of plot axis exponent

Hi,

I have a graph which usually plots x-values between 100 and 500.
However, sometimes it is required that x-values range between 8000 and
20000.

when this is displayed on the plot, the x-values are displayed as 0.8
- 2 x 10^4, which looks ugly.

there are two ways i propose round this:

1. get the plot to display the actual numbers, 8000 - 20000. How can
I do this?

2. Find the exponent of the x-values (ie 4) and then divide the x-
values through by the appropriate scaling to give 800-2000, which can
be displayed properly. an if statement can change the x-label
appropriately. How can I find the exponent of a number like this?


Thanks,

Phil

For workaround 1, try

>> set(gca, 'XTickLabel', ...
cellstr(num2str(get(gca, 'XTick')', '%.0f')))
