Hi, I'm using a heatmap plot to show zero values in a matrix. I am using h.GridVisible = 'off' to hide the grid but actually I would like to see the horizontal grid lines but not the vertical ones. Is there a way to achieve that?

Thanks

在 MATLAB Online 中打开

[X,Y,Z] = peaks(100) ;
pcolor(X,Y,Z) 
shading interp 
hold on
plot(X',Y','k')

Thanks for your feedback. I find it hard to adapt it to my situation, I simply have a 200x15 matrix made of zeros and ones and by doing pcolor(X) I sort of achieve the same thing as heatmap(X) but I'm losing the possibility to set the ticks for each column/row of the heatmap plot. I could set them but they will be set in the intersections of the points not in the middle of the rows/columns.

Should you have further suggestions please let me know, thanks again.
