Change exponent of scientific notation on plot

How do I change the scientific notation exponent on the x-axis of my plot?

What I would like to do was to change the x-axis labels, that are [0:0.5:2]*1e5, to [0:50:200]*1e3, ie, change the exponent of the scientific notation to 3 and rewrite the numbers to match it. The x-axis labels would be something like:

    0.0000e+000    50.0000e+003   100.0000e+003   150.0000e+003   200.0000e+003

But the '×10^3' would be only on the right end of the x-axis.

If you are using R2014b or later, see https://www.mathworks.com/help/matlab/creating_plots/change-tick-marks-and-tick-labels-of-graph-1.html#d119e2453

Great tip thanks Walter, upvoted!

To speed up next readers, for the exponent part, it boils down to this:

ax=gca; ax.XAxis.Exponent = 3;

This does not work anymore on 2023, however there is a possiblity of editing this using the Property Inspector while the figure remains open. @Walter Roberson any idea where how I can make this change on 2023a version?

I expect that code to work in release R2023a as it has since that property was introduced. What does "does not work" mean in this context?

• Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
• Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
• Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.

Can you show a small example of what you tried where this code didn't work as you expected?

Hi @Steven Lord, is there a way to change the axes exponents within AppBuilder axes properties, or do I have to manually code this in during app startup? Thanks.
