Hi
I was using this code for years giving me perfectly fine smith plots with white colour )inner, outer and background).
figure
sm = smithplot(gca);
hold on
% Set the background color of the outer area to white
ax = gca;
set(gcf, 'Color', 'white');
% Rest of your code
sm.ArcTickLabelVisible = 0;
sm.CircleTickLabelVisible = 0;
sm.Marker = {'+'};
sm.GridBackgroundColor = 'w';
sm.TitleTopFontSizeMultiplier = 1.75;
sm.GridLineWidth = 1;
I recently upgraded to MATLAB R2024a, and same code gives me smith plot with grau outer area, although I command for a white one.
Any recommnedation on this ?
Thanks

Ran in:
weird function. i never used it before. but setting the Figure color before plotting with the smithplot seems to use the background color of the figure. when using smithplot before setting the color, the background cannot be adjusted anymore
fig = figure;
fig.Color = 'r'; % Change 'r' to your desired color
% Create a Smith chart
s = smithplot(rand(1,10));
fig = figure;
% Create a Smith chart
s = smithplot(rand(1,10));
fig.Color = 'r'; % Change 'r' to your desired color

In the 2021 version, setting the white background worked fine for me with:
fig = figure; % create figure
set(fig, 'Color', 'white'); % then change the figure's color
When I updated to 2025, I had trouble setting the white background even when I forced it. I found a temporary solution with:
fig = figure; % create figure
s = smithplot(gca); % create the smithplot associated with the current axes
set(fig, 'Color', 'white'); % then change the figure's color
s.GridBackgroundColor = 'w'; % and chart background color
set(findall(fig, 'Type', 'Patch'), 'FaceColor', [1 1 1]);
