Is it possible to plot a cell array on y axis (imagesc function)

Hello,

I am plotting a 2D logical vector using imagesc and am trying to specify my y-axis. The information I want to use as my y-axis (names of Action Units) is stored in a 1x42 cell array. When I try to use this information as my y axis I receive the error: Error using set, Conversion to double from cell is not possible.

Is there anyway I can use this information as my y-axis?

Thanks in advance, Shannon

Where is your code ?

colormap(gray(256))
>> imagesc(happy)
>> hold on 
>> set(gca, 'XTick', x)
>> hold on 
>> set(gca, 'YTick',{'AU1','AU1-2','AU2','AU2L','AU4','AU5','AU6','AU6L','AU6R','AU7L','AU7R','AU9','AU10Open','AU10LOpen','AU10ROpen','AU11L','AU11R','AU12','AU25-12','AU12L','AU12R','AU13','AU14','AU14L','AU14R','AU15','AU16Open','AU17','AU20','AU20L','AU20R','AU22','AU23','AU24','AU25','AU26','AU27i','AU38','AU39','AU43','AU7','AU12-6'})

This is what I've put in. 'happy' is my 2D logical vector (42x1). I'm extremely new to MATLAB so unsure about what I'm doing wrong.

Use Yticklabel instead of ytick

set(gca, 'YTicklabel',{'AU1','AU1-2','aa' })

Thank you! That works perfectly
