A gap on inverse pole figure

[kevindurantnets]

Hello all,
I’m trying to plot inverse pole figures of a FCC high entropy alloy, but there is a gap at [-111] point, which is circled by a red dot. My code is shown below. How could I solve this problem?

CS = {...
'notIndexed',...
crystalSymmetry('m3m', [3.6 3.6 3.6], 'mineral', 'Nickel', 'color', [0.53 0.81 0.98])};

plotIPDF(ebsd.orientations,[vector3d.X,vector3d.Y,vector3d.Z])

Thanks in advance.

Huh... seems like a plot label is maybe sorta overlaying the corner? You could try turning off the notations. What about trying (just to see) if a different plotting size/preference makes a difference...

like if you add inside the plot command...

..., 'figSize', 'tiny')

or 'huge'...

just specifying and/or changing it to see if/how it affects the corner point.

If I shink the figure, the gap will be small, but it still exist. This problem does not seem to exist in titanium inverse pole figure.

This some kind of a bug. The reason is that the vertices of the fundamental sector are not hard coded in MTEX. You can overcome this problem by editing the file mtex/geometry/@sphericalRegion/plot.m at line 27 and increase the value 2161 to something bigger, e.g. 8641

% plot the region
omega = linspace(0,2*pi,8641);
