Hey all, I want to know is possible to have a pie chart with 5 pies so that I can change the color of each pie that I want? Just like this:

I don't have any data sets, in this case, I just want pie chart with 5 equal parts with ability to change colors.
Please let me know is this possible to do this in Matlab?
Best Regards.

One option:
p = pie(ones(1,5)); % create a pie chart with 5 equal slices
t = p(2:2:end); % get the handles to the text labels
p = p(1:2:end); % get the handles to the patches
delete(t) % delete the text labels
p(2).FaceColor = 'g'; % change the color of the second patch to green

FYI
If you prefer lighter colors like in the example in your question, you can experiment with the FaceAlpha property. For example, to make the green slice in Tommy's solution lighter, you could do this:
p(2).FaceAlpha = 0.3;

Behzad - yes, you can change the colours of each piece of the pie. To generate a pie chart with five equal pieces, just do
hPatchAndTextObjects = pie(ones(1,5))
The hPatchAndTextObjects is an array of handles to the patch and text graphics objects. On my version of MATLAB, the ordering is patch object, text object, patch object, text object, etc. To change the colour of the first patch object, just do
set(hPatchAndTextObjects(1), 'FaceColor', [1 1 0])
which will set the colour to yellow.

Hi guys,
hope you're still reading these days.
@Geoff Hayes's tip is a very good one, so you can set up all other patches' color with a for loop.
I posted the code too, it may be of help.
Thanks for maintaining the community, and best.
ax3 = nexttile;
pRoadRailway = pie(ax3, heightsRoadRailway, labelsRoadRailway);
legend(legendRoadRailway, 'Location', 'southoutside');
myColors = [0 0.4470 0.7410; ...
0.8500 0.3250 0.0980;...
0.9290 0.6940 0.1250];
%
for i = 1:2:4
set(pRoadRailway(i), 'FaceColor', myColors(i, :))
end
