error plotting, but succed when plotting order is change
显示 更早的评论
I am tring to plot instantaneous freq using code below,
subplot(311),instfreq(signal,srate,'Method','hilbert');
subplot(312), plot(t(1:end-1),instFreq1)
subplot(313),instfreq(signal,srate,'Method','tfmoment');ylim([0 25])
it can show two first figure but failed to plot last figure, so i change the order or plotting as
subplot(313),instfreq(signal,srate,'Method','tfmoment');ylim([0 25])
subplot(312), plot(t(1:end-1),instFreq1)
subplot(311),instfreq(signal,srate,'Method','hilbert');
ait it work, con someone explain why it happend? the error msg that i get is

Hi,
The error you're encountering is related to how MATLAB's graphics system handles the customization of toolbars and interaction modes within figures when using certain plotting functions. Specifically, the “instfreq” function, when used with certain methods like “tfmoment” may internally modify the figure's toolbar or interaction modes to better display and interact with the time-frequency data. This modification seems to conflict with subsequent or previous subplot customizations if not handled in the right order or without proper preparation.
When you plot the subplot using “tfmoment” first (“subplot(313)” in your reordered code), MATLAB sets up the figure's toolbar and interaction modes as needed by the “instfreq” function right at the beginning. After this setup, adding more subplots does not seem to conflict with the already established settings, allowing the other plots to be added without issue.
However, when you try to use “tfmoment” after plotting other subplots, MATLAB attempts to modify the figure's toolbar or interaction modes again, which leads to a conflict because the figure has already been partially customized by previous plotting commands which in turn throws the error message.
