Since version R2014b, MATLAB now renders graphics nicely anti-aliased (finally!)
However, this causes a glitch in the way it displays some of my figures. If I plot a line, use hold on and then plot another line in exactly the same place with a different colour, the line appears in a mottled combination of both colours. In the past, the line would simply appear as the last colour that was plotted in that location.
Here's an example of a trace in blue, with some sections (the steeper bits) showing a green line. In previous MATLAB versions, the green lines would be continuous, but now some of the blue line shows through.
Is there a neat way to work around this in the new version, or do I have to ensure that I remove any existing lines before plotting in the same place?
When overplotting, the new anti aliasing plots can have some bleed through, try
set(gcf,'GraphicsSmoothing','off')To see if it restores the functionality you're used to.
