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.

Demonstration:

load patients

tbl = table(LastName,Age,Gender,SelfAssessedHealthStatus,...

Smoker,Weight,Location);

h = heatmap(tbl,'Smoker','SelfAssessedHealthStatus');

s=struct(h);

Warning: Calling STRUCT on an object prevents the object from hiding its implementation details and should thus be avoided. Use DISP or DISPLAY to see the visible public details of an object. See 'help struct' for more information.

s.XAxis.Visible='off';

s.YAxis.Visible='off';
