MATLAB: Capaplot: Color change possible

capaplotcolorplotstatistics

Hi, I want do use a Process capability plot ('capaplot') of a dataset but the usual commands (.facecolor and .edgecolor) do not change the color of the plot. Is there a command that would work? Thanks in advance 🙂

Hi fr_sk,
I understand that you are trying to change the color of the plot.
Below is a sample code for demonstration purposes, which might be helpful in solving this issue:
% Create a capaplot, the code to create a capaplot can be found in the documentation page. 
% Documentation link : http://www.mathworks.com/help/stats/capaplot.html#bt53f2o
rng default; % For reproducibility
data = normrnd(3,0.005,100,1);
S = capability(data,[2.99 3.01])
capaplot(data,[2.99 3.01]);
grid on
% Now we use the command "gca" to get the axes where data is plotted
myPlotAxes = gca
% In myPlotAxes, choose the patch
child = myPlotAxes.Children(2)
% Change FaceColor and EdgeColor properties
child.FaceColor ='r'
child.EdgeColor ='g'
