issue colorcoding individual orientations on a PF

[jhiscocks]

I tried to post this over at the forum, but the 'post' button was nonfunctional.

After plotting my EBSD data, I can plot a pole figure with the same coloration by using the following code;

oM =  ipdfHSVOrientationMapping(ebsd_scratch('Magnesium'));
color =  oM.orientation2color(ebsd_scratch('Magnesium').orientations);
figure;
  plotPDF(ebsd_scratch('Magnesium').orientations,h,'upper','projection','eangle','points',10000, 'MarkerSize',1,'property',color);

I can also select two points on the map and plot them as a pole figure using the following code

[x,y]=ginput(1);
ori1=ebsd_scratch(x,y).orientations;
[x,y]=ginput(1);
ori2=ebsd_scratch(x,y).orientations;
h=[Miller(0,0,1,ebsd_scratch('Magnesium').CS),Miller(1,0,0,ebsd_scratch('Magnesium').CS)];
figure;
plotPDF (ori1,h,'upper','projection','eangle','MarkerSize',10);
hold on;
plotPDF (ori2,h,'upper','projection','eangle','MarkerSize',10);
hold off;

however when I try to combine the two and plot the two points ori1 and ori2 with colors using the following command I get an error message

h=[Miller(0,0,1,ebsd_scratch('Magnesium').CS),Miller(1,0,0,ebsd_scratch('Magnesium').CS)];
figure;
plotPDF (ori1,h,'upper','projection','eangle','MarkerSize',1,'property',color);
hold on;
plotPDF (ori2,h,'upper','projection','eangle','MarkerSize',1,'property',color);
hold off;

This is the error message

Warning: Error creating or updating Patch
 Error in value of property  FaceVertexCData
 number of colors  must be equal to number of vertices when MarkerFaceColor is Flat

What am I doing wrong? I would also like to be able to colorise these two points in other ways, for example using grains.meanOrientation

Hi jhiscocks,

In the most recent MTEX version the use of the property flag is obsolete. Data are always placed as the second argument to a plotting command, i.e.,

plotPDF (ori1,color,h,'upper','projection','eangle','MarkerSize',1);

I hope this helps,

Ralf.
