removing edges (fractures) from lines

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?

[AndresVar]

can you replicate with a short code?

Are you just using plot and saveas?

It looks normal for me, but your image seems zoomed in

I edited it after ploting the function. I used the so called "Property Inspector" and of course the export dialog.

Yes, the image is zoomed in. I wanted the lines to be a bit more precise.

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);

Kindly provide the code and configuration of "Property Inspector" used for generation of the above plots for further help.

Besides, a set of user contributed functions, available at the MATLAB Central File Exchange, can be used to assist you with exporting graphics:
