setting range on colorbar in appliction designer

I would like to be able to set the range of a color bar in the application designer

The line below is causing an error.

Im not sure how to link it to the object (whether app.UIAxes or c).

function openfile(app, event)

[file,path]=uigetfile({'*.jpg';'*.bmp';'*.gif';'*.tiff'}, 'Select file');

app.a= double(imread(file));

app.a= -(0.0316*app.a) +8.3;

imagesc(app.a,'Parent',app.UIAxes);

maxval = max(max(app.a));

minval = min (min(app.a));

c = colorbar(app.UIAxes)

c.clim ([minval maxval]); <- causes error

end

thank you

Replace

c.clim ([minval maxval]);%    <- causes error

with

app.UIAxes.CLim = [minval maxval];
