HI all,
I am plotting 6 subplots in one figure in arrangement as 2 rows and 3 colums.
I want two colorbar with different colormap for every row.
How can I do it?
Thanks in advance.

- Use tiledlayout instead of subplot
- Assign the colormap to the axes using the axes handles
- Using tiledlayout, position the colorbars to the east|west|north|south
Full demo of these 3 steps
tcl = tiledlayout(2,3); % STEP 1
ax = gobjects(1,6);
for i = 1:6
ax(i) = nexttile();
peaks(15);
if i>3
colormap(ax(i),'hot') % STEP 2
else
colormap(ax(i),'cool')
end
end
z = 3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... - 1/3*exp(-(x+1).^2 - y.^2) z = 3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... - 1/3*exp(-(x+1).^2 - y.^2) z = 3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... - 1/3*exp(-(x+1).^2 - y.^2) z = 3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... - 1/3*exp(-(x+1).^2 - y.^2) z = 3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... - 1/3*exp(-(x+1).^2 - y.^2) z = 3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... - 1/3*exp(-(x+1).^2 - y.^2)
% STEP 3
cb1 = colorbar(ax(3));
cb1.Layout.Tile = 'east';
cb1.Label.String = 'Vanilla Ice';
cb1 = colorbar(ax(6));
cb1.Layout.Tile = 'east';
cb1.Label.String = 'MC Hammer';

Hi Adam,
Thanks for your reply.
Can you tell me If I want to use caxis for the each tiledplot, is it possible?

Indeed!
Call the clim function for each axis specifying the same limits since you're using 1 colorbar scale for those axes.

Hello,
I understood that you want to display different colors in a subplot.
I have tried it from my end and below is the solution for the same.
x=0:0.1:10;
y1 = cos(x)
y2 = sin(x)
subplot(2,2,1)
plot(x,y1,'Color','r') ;
colorbar
subplot(2,2,2)
plot(x,y2,'Color','r') ;
colorbar
subplot(2,2,3)
plot(x,y1,'Color','b') ;
colorbar
subplot(2,2,4)
plot(x,y2,'Color','b') ;
colorbar
In this example we have used 2x2 subplot and assigned red color to first row and blue color to second row. In this way we can set colors to individual plots as well.
We may also include different styled markers with different colors on the graph line. For such more options and better understanding of this concept, kindly refer to the following resources.

Hope you find it helpful!
