Hello guys
Here i wanted to save a plot having an orange background color. An example code is shown below:
b_col = [255, 150, 0]; % orange color code
b_col = b_col./255;
plot(rand(10,1));
set(gca,'color',b_col);
set(gcf,'inverthardcopy','off');
print('test','-djpeg','-r900')
The above code result in a plot with orange background color, however, when i save it contains a gray color surrownding it as shown in the test image file below. At this point i needed a support in removing a gray color but instead replaced by white color.
Thanks for your supporting

Ran in:
b_col = [255, 150, 0]; % orange color code
b_col = b_col./255;
f = figure;
f.Color = [1 1 1]; % Set the color to white
plot(rand(10,1));
set(gca,'color',b_col);

Dear Simon, thank you for the quick response. Your suggestion fixed the gray color problem, however while i print it the orange color is converted to white too, which is not the case i wanted.
I used the comand below to save my plot.
print('test','-djpeg','-r900')

Try exportgraphics() instead of print().

@TESFALEM ALDADA, you forgot to list your version when you posted. You must have an old version. exportgraphics() was introduced in r2020a.
