Save n*Number of Pie Charts Generated from a loop

Hello Everyone,

I am using following code to generate pie charts:

myDir = uigetdir;

for d = 1:length(Dataset)
baseFileName = (strcat('Figure', num2str(d),'.jpg'));
fullFileName = fullfile(myDir, baseFileName);
imwrite(p, fullFileName);
end

I am incurring following error:

Error using imwrite (line 420)

Expected DATA to be one of these types:

numeric, logical

Instead its type was matlab.graphics.primitive.Data.

Error in graphs (line 37)

imwrite(p, fullFileName);

Note: Except imwrite code, pie charts are generated.

Any help would be appreciated :-)

Regard,s

Explanation of the problem

The primary resource to go to with problems like these is the documentation which describes what the first input should be to imwrite().

https://www.mathworks.com/help/matlab/ref/imwrite.html#btv3cny-1-A

That link shows that the first input should be a matrix of image data. It appears you're inputting the handle to a pie chart.

Solution

From your title I understand that you want to merely save the pie charts. Use saveas().

Thank you Adam Danz, saveas(). works :-).
