MATLAB: How to have multiple plots in a figure with preset height and compact spacing

Question

I want to have 2 plots in a figure stacked vertically with preset height (both 3cm) and compact spacing between them. I am using a tiled chart layout since it has the option for compact spacing, but when I try to set the height using the "Position" argument, I get the following warning.

Warning: Unable to set 'Position', 'InnerPosition', 'OuterPosition', or 'ActivePositionProperty' for objects in a TiledChartLayout

On maximizing/minimizing the generated figure window, it is observed that the height of the axes is not set to the constant value as required. My code is given below:

 

tiledlayout(2,1);
nexttile;
plot(1:10);
ax=gca;
ax.Units='centimeters';
ax.Position(4)=3;
nexttile;
plot(1:20);
ax=gca;
ax.Units='centimeters';
ax.Position(4)=3;

Answer 1

In order to have multiple plots with compact spacing and preset height, you can have separate axes objects in the same figure and set their positions as required. Please take a look at the example below which illustrates this. Here, instead of having a tiled chart layout or subplot, two separate axes objects are created and their positions are specified explicitly.

 

f = figure();
ax1 = axes(f);
ax2 = axes(f);
ax1.Units = 'centimeters';
ax2.Units = 'centimeters';
axHeight = 3;
ax1.Position(4) = axHeight;
ax2.Position(4) = axHeight;
plot(ax2,1:10,1:10);
plot(ax1,1:20,1:20);
spacing = 0.3;%change this to obtain compactness
% position ax2 above ax1 with some spacing. using TightInset will account for any axes labels.
ax2.Position(2) = ax1.Position(2) + ax1.Position(4) + ax1.TightInset(4) + ax2.TightInset(2) + spacing ;
