No 'CData' property on bar graph

I'm trying to make a bar graph and adjust the colors of individual bars. The most helpful online answers on how to do this involve using the 'CData' property of the bar object. However, in my particular bar graph, generated by the following code, there is no 'CData' property, and I'm confused as to why. Any help would be greatly appreciated!

eyesPlot = bar(1:4,eyesArray(:,2));

Which release are you using?

R2017a

Answer 1

[Tom Holmes]

This worked for me with 2017a release:

figure
BarMatrix = [your_matrix_here];
b = bar(BarMatrix,1,'LineStyle','none');
CData = lines(4);
for k = 1:size(BarMatrix,2)
  b(k).FaceColor = CData(k,:);
end

Answer 2

[Roger Breton]

Does not work for me?

I use:

data = [1 2 3 4];

figure

BarMatrix = [1 2 3 4];

b = bar(BarMatrix,1,'LineStyle','none');

CData = lines(4);

for k = 1:size(BarMatrix,2)

b(k).FaceColor = CData(k,:);

end

And all I get are four solid bars of blue?
