Different color appeared while using helperSpec​trogramAnd​SpectralKu​rtosis() function

Hi, I just started to learn Matlab and quite new to Matlab. I followed the example in Rolling Element Bearing Fault Diagnosisn but my plot of using helperSpectrogramAndSpectralKurtosis(xOuter, fsOuter, level) get different color from the example . What caused it and how do I fix it?

I found the solution simply add

colorball
caxis('auto')

below the code of

plot([xlimits1 NaN xlimits1], [fc_scaled-BW_scaled/2 fc_scaled-BW_scaled/2 NaN fc_scaled+BW_scaled/2 fc_scaled+BW_scaled/2], '--')

in the matlab script file of helperSpectrogramAndSpectralKurtosis.m, then this problem is solved.
