App With Bar Graph

Hello! I can manage to get my data values to plot correctly on the app, but I just want to change to color of the bars. This is the script I tried running with the color change, where I tried using the Cdata to get different colored bars. Any help is appreciated!!

function UIAxesButtonDown(app, event)

bf = app.BodyFatEditField.Value;

Dmax = app.DiameterMaxEditField.Value;

Dmin = app.DiameterMinEditField.Value;

Psys = app.SystolicPressureEditField.Value*0.0013;

Pdia = app.DiastolicPressureEditField.Value*0.0013;

Pdrop = Psys-Pdia;

Ddrop = Dmax-Dmin;

EM = (Pdrop*Dmax)/Ddrop;

patients = [1 2 3 4 5];

bodyfat = .10;

bodyfatc = .22;

bodyfatl = .42;

bodyfath = .67;

EMc = 0.4025;

EMh = 0.3248;

EMk = 0.3177;

EMl = 0.488;

bf = [bodyfat bodyfath bodyfatc bodyfatl app.BodyFatEditField.Value; EMk EMh EMc EMl EM];

bar(app.UIAxes, patients,bf, 'FaceColor', 'flat')

b.Cdata = [0 .5 .5; .5 0 .8];

From my understanding, you want to add color to bars in bar plot.

This can be achieved using CData in with bar plot function

Refer to the following documentation:

https://in.mathworks.com/help/releases/R2019b/matlab/ref/bar.html#d117e81932

As an example

function ButtonPushed(app, event)
   y = [1 3 5; 3 2 7];
   b = bar(y,'Parent',app.UIAxes,"FaceColor",'flat');
   b(1).CData = [0 .5 .5];
   b(2).CData = [.5 0 .8];
end
