How do I rescale the x-axis?

Hi,

I am plotting a certain physical quantity over time [fs]. I would like to rescale the x-axis so that it displays time in units of picoseconds (this will then get rid of the annoying power of 10 that appears on the x-axis). I am unsure how to do this. Can someone offer a suggestion?

Thanks!

The simplest way is to change the values in your plot command. Divide all your fs times by 1000 and now they're picosecond times.

instead of: plot(time_vector , function_of_time)

try: plot(time_vector/1000, function_of_time)

You can also force limits on your x-axis both with the xlim and axis commands. You can set your minor and major tick marks with the set command or the plottools UI. But start with the above.

Great suggestion, thanks!
