How to save clustergram as fig file using code?

I generate a clustogram using R2016a,

    cgo = clustergram(rand(94,250),...
        'RowLabels',repmat({'rowLabel'},1,94),...
        'ColumnLabels',repmat({'ColLabel'},1,250),...
        'Colormap',redbluecmap,...
        'Cluster','column',... %'column'/'row'/'all' or
        'DisplayRange',1,...
        'DisplayRatio',[0.00001,0.00001]);

The clustergram was shown.

To save it as fig file, one way is to click File-Export Setup-Export, then select fig format.

I want to find a way to save it by code, but save(cgo,'path') does not work as cgo is not a figure object.

One solution is call

    fig = cgo.plot

this will show another figure that can be saved as regular figure. However, one info is lost in fig:

When I click on datapoint on cgo image, it will pop up a small window showing x/y label information, but this information is lost if I click on the fig object, andthis information replaced by RGB information instead.

Is there a code to do the examly same thing as "click File-Export Setup-Export, then select fig format."?

One way:

plot(cgo);
saveas(gcf,'filename1.png')

However, the figure is without colorbar. Anyway to add it? The way below does not work.

plot(cgo);colorbar;

Thanks!
