How to stop log axis shift

Hello,

I am trying to generate 5 different 3d waterfall plots (each representing a flow speed from 20m/s to 60m/s). One of the axes in each of the graphs represents frequency and is set to be logarithmic by using: 'set(gca, 'XScale', 'log');'

The frequency values within the 'waterfall' function are normalised by dividing by the respective flow speed.

Eg: for 20m/s, h = waterfall(F/20, blowingRates, DPWL20_filtered');

Since F starts at 0, I wasn't worried about the lower x limit, but I set the upper limit to max(F)/60 for all plots to ensure they all cover the same X range: xlim([0 max(F)/60])

When I try to plot these, I notice the frequency axes shift, despite enforcing xlim

Is there a better way to keep the axes the same for all plots?

Here are images for the plots so far:

You can't plot 0=10^(-inf) on a log scale.

The lower x limit must be a positive number.

For example, try xlim([0.1 max(F)/60]) or xlim([0.01 max(F)/60]).

Of course, 0.1=10^-1 and 0.01=10^-2.

Don't know how I missed that, thanks a lot! Works well
