Dear fellows,

I try to export some plots as png files. But sadly all of them have these kind of edges within.

How can I remove these? Or avoid them?

Hi @math_man_rob,

Can you mention the settings done through "Property Inspector"?

Hi math_man_rob,

I understand from your query that you are interested in removing the edges in the exported plots.

The issue you're experiencing might be related to the renderer, if you switch to the "painters" renderer the issue goes away as shown in the image attached below. This option works well for axes in a 2-D view. Furthermore, you can use "GraphicsSmoothing" to reduce the appearance of jagged lines in an axes graphic.

%% Using opengl renderer
plot([-10 :0.01 : 10], [-10 :0.01 : 10].^2)
set(gcf, 'Renderer', 'opengl');
exportgraphics(gcf, 'filename.png', 'Resolution', 1200);
%% Using painters renderer
plot([-10 :0.01 : 10], [-10 :0.01 : 10].^2)
set(gcf, 'Renderer', 'painters', 'GraphicsSmoothing', 'on');
exportgraphics(gcf, 'filename.png', 'Resolution', 1200);
