How to enable the colorbar to only show the vertical scale with values ?

1 view (last 30 days)
I am using a colorbar command to have a vertical scale besides my polarplot. When its position property is used it is working fine, but i want it to appear as the same size of the polarplot. I have used the location propert to make it appear so. But now the problem is it was showing colormap with colors. I have attached the pictures and link to my previous answered question. All this mess occurs because i want my legend to be displayed under the plot so i have used outside position argument of legend.

Are you using polar() or polarplot()? The link to your previous questions shows both, so which one are you using? The correct answer should be polarplot unless you're using a release of matlab prior to r2016a.
Also, it would be easier to help if you provide a working example that we can copy and run. The inputs could be attached as a mat file or they could be fake data created within the code that you share.

I am using polarplot() only and in first link you can see my code and answers to the code to attach a scale. That is all i am using. In addition i have modified the code with exceptions as below.
a=0:0.1:2*pi;
b=rand(size(a));
c=0.5*rand(size(a));
% create the plots
figure
hold off
polarplot(a,b,'g-')
hold on
polarplot(a,c,'r-')
hLegend = legend('a','b','Location','SouthOutside');
% hLegend.Position = [0.7830 0.8806 0.1036 0.0869];
% Add the bar, grab handles
hBar = colorbar;
% hBar.Position = [ 0.1112 0.1024 0.001 0.8167];
hBar.Location = 'WestOutSide'
hBar.Ticks = [0.05:0.1:1 ];
hBar.TickLabels = [10 0 -10 -20 -30 -30 -20 -10 0 10 ];

Dear jonas, i don't know about how to create separate axis. Please see the code in comments.

The plot below was produced using your exact code as it appears in the comment under the question plus the following two lines at the end,
hBar.Position(3) = 0.00001; % Make it narrow
hBar.Position(1) = 0.15; % move it leftward
Is this what you're looking for?
Using r2020a Update 5.

BTW, I have no idea how to interpret that scale.
Why are there two 0s and 10s?
Why does it go from -10 to 0 at the bottom?
What do those values even mean? -- you could use ylabel(hBar, 'Label')

Not sure if this answers your question, but it's an alternative to using a colorbar for scale. Also did not use the "outside" argument of legend as you mentioned it being problematic.
a=0:0.1:2*pi;
b=rand(size(a));
c=0.5*rand(size(a));
% create the plots
figure
hold off
ax(1) = gca;
polar(a,b,'g-')
hold on
polar(a,c,'r-')
%add legend and change position
hLegend = legend('a','b','orientation','vertical','location','south');
hLegend.Position(1:2) = [0.8 0.8]
%make new axis and align with first one
ax(2) = axes('color','none');
ax(2).XAxis.Visible = 'off';
ax(2).Position([2,4]) = ax(1).Position([2,4]);
