How do we concatenate two imagesc figures ( 2D matrix) into one figure ( one below the other stacked) without any gaps?

I have two figures (Fig1 and Fig2): They are two separate imagesc plots.

How do i get a plot of concatenated version of these two plots as shown in concatenated.png( attached) ?

There should not be any gaps between the two plots as we obain in subplot.

code:

figure(4);
imagesc(Rng,Vel,RDM_1);
xlabel('---> Range (m)');ylabel('---> Velocity (m/s)')
title('Range-Doppler Map 1');
figure(5);
imagesc(Rng,Vel,RDM_2);
xlabel('---> Range (m)');ylabel('---> Velocity (m/s)')
title('Range-Doppler Map 2');

I need to concatenate the 2D matrix RDM_1 and RDM_2 one below the other without any gap ( as shown in concatenate.png).

Normally I would tell people to adjust the XData and YData properties of the image() object. (Your Rng and Vel are already setting the XData and YData properties.) However, I see from your diagram that you want the axes to be distinct for the two of them. In this situation, @Harikrishnan Balachandran Nair has the right answer, to use multiple axes.

I wanted both the plots to have a single x axis and distinct y axis

[Walter Roberson]

I suggest using linkaxes() to ensure the x axes are the same.

Thanks will do that :)

I understand that you are trying to have two 'imagesc' plots stacked vertically, without any gap in between them.

A Possible workaround for this would be to have two 'axes' object defined on the same 'figure' handle , positioned in such a way that they are stacked vertically without any gap in between.

This can be done by adjusting the 'Position' property of the axes object.You can refer to the following code for the same.

fig=figure;
axes1=axes(fig);
axes2=axes(fig);

axes1.Position(1,4)=axes1.Position(1,4)/2;
axes2.Position(1,4)=axes2.Position(1,4)/2;
axes2.Position(1,2)= axes1.Position(1,2)+axes1.Position(1,4);
imagesc(axes1,Rng,Vel,RDM_1);
imagesc(axes2,Rng,Vel,RDM_2);

Great !

Thanks for the Answer :)
