Hello, I'm having problems to plot my data as a bar graph, with different colours for the different bar groups. I've read a bit about setting colours for bars, and that you would have to plot them individually to do so: https://se.mathworks.com/matlabcentral/answers/uploaded_files/59506/barchart.m
The problem is that I want to plot multiple bars grouped together in one plot, as automatically done when you have your data in a matrix. That looks like this and is almost the way I want it (but has the wrong colours):
Data(1,1)= 0.91;
Data(1,2)= 0.91;
Data(2,1)= 0.65;
Data(2,2)= 0.79;
barh(Data,1)
ylabel('gradient [permil]');
set(gca,'yticklabel',{'Control','Gas'});
set(gca,'YTickLabelRotation',90);
The first set is Data is duplicated because I actually have groups of different sizes and matlab doesn't allow that (but that's another problem). It would be fine for me to make one wide black bar out of this first set. So I would want to make the first two bars black, and the second two another colour, etc. (I will add more data). I tried doing this, but then the bars are plotted over one another:
mydata=Data;
figure(1)
hold on
a=1
for i = 1:length(mydata(a,:))
h=barh(i,mydata(i,a));
if i == 1
set(h,'FaceColor','black');
elseif 1 == 2
set(h,'FaceColor','blue');
else
set(h,'FaceColor','red');
end
a=a+1;
end
hold off
This seperation into groups goes automatically in my first example, as I use a matrix. I just can't figure out how to do it when I plot them stepwise to get a handle on the colours. I hope you can help! Thank you
