# Plotting Individual Orientations

Basics of the plot types for individual orientations data

This section gives an overview over the possibilities that MTEX offers to visualize orientation data.

 On this page ... Scatter Pole Figure Plot Scatter (Inverse) Pole Figure Plot Scatter Plot in ODF Sections Scatter Plot in Axis Angle or Rodrigues Space Orientation plots for EBSD and grains

Let us first import some EBSD data with a script file

`mtexdata forsterite`

and select all individual orientations of the Iron phase

`ebsd('Fo').orientations`
```
ans = orientation
size: 152345 x 1
crystal symmetry : Forsterite (mmm)
specimen symmetry: 1

```

## Scatter Pole Figure Plot

A pole figure showing scattered points of these data figure can be produced by the command plotPDF.

`plotPDF(ebsd('Fo').orientations,Miller(1,0,0,ebsd('Fo').CS))`
```  I'm plotting 1250 random orientations out of 152345 given orientations
You can specify the the number points by the option "points".
The option "all" ensures that all data are plotted
``` ## Scatter (Inverse) Pole Figure Plot

Accordingly, scatter points in inverse pole figures are produced by the command plotIPDF.

`plotIPDF(ebsd('Fo').orientations,xvector)`
```  I'm plotting 12500 random orientations out of 152345 given orientations
``` ## Scatter Plot in ODF Sections

The plotting of scatter points in sections of the orientation space is carried out by the command plotSection. In the above examples, the number of plotted orientations was chosen automatically such that the plots not to become too crowded with points. The number of randomly chosen orientations can be specified by the option points.

`plotSection(ebsd('Fo').orientations,'points',1000,'sigma','sections',9)`
```  plotting 1000 random orientations out of 152345 given orientations
``` ## Scatter Plot in Axis Angle or Rodrigues Space

Another possibility is to plot the single orientations directly into the orientation space, i.e., either in axis/angle parameterization or in Rodrigues parameterization.

`scatter(ebsd('Fo').orientations)`
```plot 2000 random orientations out of 152345 given orientations
``` Here, the optional option 'center' specifies the center of the unique region in the orientation space.

## Orientation plots for EBSD and grains

Since EBSD and grain data involves single orientations, the above plotting commands are also applicable for those objects.

Let us consider some grains detected from the EBSD data

`grains = calcGrains(ebsd);`

Then the scatter plot of the individual orientations of the Iron phase in the inverse pole figure is achieved by

`plotIPDF(ebsd('Fo').orientations,xvector,'points',1000, 'MarkerSize',3);`
```  I'm plotting 1000 random orientations out of 152345 given orientations
``` In the same way, the mean orientations of grains can be visualized

```hold all
plotIPDF(grains('Fo').meanOrientation,xvector,'points',500, 'MarkerSize',3);
hold off```
```  I'm plotting 500 random orientations out of 4092 given orientations
``` One can also use different colors on the scatter points

```h = [Miller(1,0,0,ebsd('Fo').CS),Miller(1,1,0,ebsd('Fo').CS)];
```  I'm plotting 1250 random orientations out of 152345 given orientations
You can specify the the number points by the option "points".
The option "all" ensures that all data are plotted
``` or some arbitrary data vector

```plotSection(grains('Fo').meanOrientation,grains('Fo').area,...
'sigma','sections',9,'MarkerSize',4);```
```  plotting 2000 random orientations out of 4092 given orientations
```
