Intragranular Misorientation Distribution for Selected Grains

[Mustafa Rifat]

Hello MTEX Community,

I want to find intragranular misorientation of selected grains from my ebsd plot. I am trying to do something like this demo page: https://mtex-toolbox.github.io/HomepageOld/files/doc/GrainMisorientationAnalysis.html#22

I got some help from this page also: https://mtex-toolbox.github.io/GrainOrientationParameters.html

Now what I am trying is like this:

[grains,ebsd.grainId] = calcGrains(ebsd);

%My grain Ids are 489 and 490

ori = ebsd(ebsd.grainId == 490).orientations;

mis2mean = inv(grains(490).meanOrientation) .* ori;

figure

plotAngleDistribution(mis2mean)

This gives me a plot like this:

If I do the same for grain 489, I get another plot like this.

However, I want a single histogram containing data for both grains. I want to tell by looking at the histogram how the distribution looks like together i.e. is the distribution bimodal (the grains have very different intragranular misorientation distribution) or not.

Can anyone help me in this regard?

Thank you!
