How can I plot a kurtogram into axes of my app?

Hello everybody,

I am building an app for bearing diagnosis and I want to display a kurtogram computed by

kurtogram(signal, fs, level)

but I don't know how to plot this into axes of my app.

For example a simple plot-command is like:

plot(app.Spectra, app.fs, app.spec);

-> x-axes: f, y-axes: spectral values and plot into app.Spectra, a plot in my app.

But how can I do it with kurtogram()?

kurtogram(app.Kurt, signal, fs, level)

doesn't work.
