How to change color for stacked bar chart

Hi

I am wondering how I can change the color of the bars in a stacked bar chart. The code below gives me the error message "Expected one output from a curly brace or dot indexing expression, but there were 2 results." I wanted to apply blue \ hatch on the gray column, but so far I am not even able to change the color of the bars. I am able to make all bars in blue hatch \ with white background.

I have added a png to show what I want. I changed the colors in the png after running the script with the mouse, and therefor I do not have the option to export the figure as eps (better quality) with correct colors.

ba = bar(y,'stacked', 'FaceColor','flat');
ba.CData(1,:) = [0.5 0.5 0.5]
ba.CData(2,:) = [0 0 1]

applyhatch_plusC(gcf,'\','b');

Try this:

y = [50 50; 25 75; 30 70];

figure
ba = bar(y,'stacked', 'FaceColor','flat');
ba(1).CData = [0.3 0.3 0.7];
ba(2).CData = [1 1 1]*0.8;

Experiment to get the result you want.

Yes!! Thank you so much! You do not know how to apply hatches as well? I do not know how to use the "applyhatch_plusC" function on only the upper part of the columns.

As always, my pleasure!

I am not familiar with the ‘applyhatch_plusC’ function. I did manage to get the x-coordinates of the bar edges (the ‘BL’ matrix):

XD = ba(2).XData;
BW = ba(2).BarWidth/2;
BL = [XD(:)-BW XD(:)+BW];                   % Bar Limits

That is the best I can do. (The y-coordinates are the values of the ‘y’ matrix, and also the zero baseline.) IIf you have the Symbolic Math Toolbox, see if the MuPad plot:Hatch (link) function can do what you want.

Thanks again! For future people searching for a solution to what I have been trying: I was not able to make 'plot::Hatch' work, so I ended up using 'hatchfill2' which worked great, except for the legend. To make it work with the legend 'legendflex' can be used, but I was not able to achive what I wanted with positioning so I ended up using indesign to fix the legend.

Your Comment certainly argues for a function that combines all of those features.
