Axes Alignment edit page

In MTEX each plottable variable has a property how2plot which tells MTEX how to align the corresponding coordinate system on screen.

v1 = vector3d(1,1,1)
v2 = vector3d(-1,1,1)
v1.how2plot

plot(v1,'upper','label','v_1')
annotate([xvector,yvector,zvector],'labeled','backgroundcolor','w')
v1 = vector3d
  x y z
  1 1 1
 
v2 = vector3d
   x  y  z
  -1  1  1
 
ans = plottingConvention
 
  outOfScreen: (0,0,1)
  north      : (0,1,0)
  east       : (1,0,0)

The property how2plot is a handle class of type @plottingConvention. We can change it by setting north, east or outOfScreen to other directions.

v1.how2plot.outOfScreen = yvector
plot(v1,'upper','label','v_1')
annotate([xvector,yvector,zvector],'labeled','backgroundcolor','w')
v1 = vector3d
  x y z
  1 1 1

Note that because @plottingConvention is a handle class, i.e. changing v1.how2plot changes also v2.how2plot 

v2.how2plot

nextAxis
plot(v2,'upper','label','v_2')
annotate([xvector,yvector,zvector],'labeled','backgroundcolor','w')
ans = plottingConvention
 
  outOfScreen: (0,1,0) 
  north      : (0,0,-1)
  east       : (1,0,0)

In order to have different plotting axes alignments within one MTEX session we have to define a new @plottingConvention by

% instantiate a new plotting convention and sets it up
pC2 = plottingConvention; pC2.north = yvector

% assign this plottingConvention to v2
v2.how2plot = pC2;

% plot v1 and v2 in separate plots
plot(v1,'upper','label','v_1')
annotate([xvector,yvector,zvector],'labeled','backgroundcolor','w')
nextAxis
plot(v2,'upper','label','v_2')
annotate([xvector,yvector,zvector],'labeled','backgroundcolor','w')
pC2 = plottingConvention
 
  outOfScreen: (0,0,1)
  north      : (0,1,0)
  east       : (1,0,0)

When initiating a new vector3d MTEX uses plottingConvention.default as default plotting convention. This default plotting convention can be changed by

plotx2north
plotzOutOfPlane
plot([xvector,yvector,zvector],'upper','labeled','backgroundcolor','w')

When importing data those might be associated with a plotting convention that is different to the default one

mtexdata dubna

pf.how2plot
plot(pf{1:4})
pf = PoleFigure (xyz)
  crystal symmetry : Quartz (321, X||a*, Y||b, Z||c*)
 
  h = (02-21), r = 72 x 19 points
  h = (10-10), r = 72 x 19 points
  h = (10-11)(01-11), r = 72 x 19 points
  h = (10-12), r = 72 x 19 points
  h = (11-20), r = 72 x 19 points
  h = (11-21), r = 72 x 19 points
  h = (11-22), r = 72 x 19 points
 
ans = plottingConvention
 
  outOfScreen: (0,0,1)
  north      : (0,1,0)
  east       : (1,0,0)

Note that all quantities derived from those data will inherit the stored plotting convention

odf = calcODF(pf,'silent');

plotPDF(odf,pf.allH{1:4})

We may also set the default plotting convention to the plotting convention of the imported data by

pf.how2plot.makeDefault
plottingConvention.default
ans = plottingConvention
 
  outOfScreen: (0,0,1)
  north      : (0,1,0)
  east       : (1,0,0)
 
 
ans = plottingConvention
 
  outOfScreen: (0,0,1)
  north      : (0,1,0)
  east       : (1,0,0)
