Is this the heatmap from the Bioinformations toolbox? https://www.mathworks.com/help/bioinfo/ref/heatmap.html

Or is it the new (R2017a) heatmap() that is for table objects?

It is the new (R2017a) heatmap().

There are no x and y axis ticks for the new R2017a heatmap object. There is at most the ticks inside the colorbar beside the drawing. Is it the colorbar tick marks that you want to remove?

Imshow has an 'InitialMagnification' setting.

Thanks, Walter! Just a quick note: Calling xlabel or ylabel after doing this may bring back the ticks. Took me a while to figure out why your snippet didn't seem to be working.

在 MATLAB Online 中打开

h=heatmap(x,y,c);
s=struct(h);
s.XAxis.Visible='off';
s.YAxis.Visible='off';

I actually want a Y axis to have fewer number of values than the number of rows of the data. Plz lemme know if there is a way to do this?

Also, when I save the figure, the original numbering (matching the dimensions of the data) overwrites the alternate numbering. Though, this problem can be solved by taking a screenshot of the figure, instead of saving it.
