Heatmap chart appearance and behavior. expand all in page. HeatmapChart properties control the appearance and behavior of a HeatmapChart object. By changing property values, you can modify certain aspects of the heatmap chart. For example, you can add a title: h = heatmap([1 3 5; 2 4 6]); h.Title = 'My Heatmap Title';

How do I set the label between two ticks? In the following example, I want 'Decrease', 'Slight Decrease', 'Slight Increase', and 'Increase' between the ticks, while 'No Change' stays below the tick: Thanks! 0 Comments. Show …Setting the colorbar's Limits only changes what part of the color spectrum appears on the colorbar as you demonstrated with the surf plot. It's the same as setting an axis limit using xlim|ylim. Setting the ColorScale affects the colormap and colorbar but that only offers linear|log options.2. If you want the 0 value to actually be in the middle of your colormap, you will want to set your color limits (using caxis of the CLims property of the axes) after determining the maximum magnitude of your data: limit = max(abs(data(:))); caxis([-limit, limit]); answered Mar 30, 2016 at 14:28.

Your custom colormap happened to work because red was used for pixels with a value of about 0.5 - of which there were none. What you need to do is correctly set the color limits for your axes:, c = colorbar; The default location of the colorbar is on the right side of the axes. However, you can move the colorbar to a different location by setting the Location property. In this case, the ' southoutside' option places the colorbar below the axes. c.Location = 'southoutside'; You can also change the thickness of the colorbar., To display the colorbar in a location that does not appear in the table, use the Position property to specify a custom location.

Second, your colormap is probably already correct (didn't check). You probably just want to change the visible ticks of it, which you can do with set(c, …, Matplotlib 1.3.1 - It looks like the colorbar ticks are only drawn when the colorbar is instanced. Changing the colorbar limits (set_clim) does not cause the ticks to be re-drawn. The solution I found was to re-instance the colorbar in the same axes entry as the original colorbar.
