Color Display of Pole Figures

POXX provides a VGA color display of pole figures or ODF sections in polar or Cartesian coordinates. Up to 16 plots can be combined on the screen (in arrangements 1, 2x2, 3x3, 4x4). A low resolution display of ODF's in Cartesian coordinates is also possible, without contours. Several options can be chosen (equal area or stereographic projection, smoothing, linear or log intensity scale, color distribution with specified minimum and maximum). A cursor arrow allows you to determine angular positions in the pole figure, accessible by F6 key. This works only if the number of pole figures is not greater than 4. The F5 key sort out unnecessary informations for printing.

The color display on the monitor can be captured as a .pcx file for later editing and printing in paintbrush (you must provide the screen capture routine) or the screen can be photographed to prepare slides for presentations (which we find most efficient). Screen capture as .tif file is useful for insertion in Word as an image (provide good printing).
For screen capture of a .pcx file you must load, before execution, a memory resident DOS program such as SNAP, SAVE, GRAFLASR, or similar utility. This is easily done automatically by adding a line to the AUTOEXEC.BAT file, for loading the memory resident program when the computer is booted up. Then, depending on the actual utility loaded, use the shift key combination. A hard copy can be printed from the PaintBrush program in Windows or utilities, which also allows for some editing if desired. For publication it is better not to use high resolution gray shades but instead 300 bpi (this will also Xerox much better). The printer resolution can be chosen in the Control Panel Printer or in a facility such as Photofinish.

Warning : Only 3 digits for hkl are displayed. Values are truncated to show only last digit (e.g. 0 0 12 appears as 0 0 2; -1 0 11 as 1 0 1).

Select an ODF or pole figure input file. Default file is C:\BEARTEX\DEMO.XPE

The window will then tell you how many plots you have on the file, minimum and maximum and give you a list of the pole figures which you have on the file. You can choose a minimum and maximum between which colors will be spread. This can be larger or smaller than actual minimum/maximum.

There are several Plot Display Options to choose. The most important ones are:
Smoothing: smoothes the data set.
Contours: adds contours between color regions.
Low resolution is quick but coarse (not recommended, default for ODF in Cartesian).
For most displays log-scale is appropriate, unless you have negative numbers or for Mima .xpf files.
You can plot all the data or restrict them to a specific sector. The cubic sector can be useful.
Choose between equal area and stereographic projection.
Negative values can be set to zero (Log. plot).
Pole figures and ODFs can be plotted in polar coordinates (preferred) or in orthogonal coordinates.
If you have misorientation data the program will put shading over the redundant region.

After selecting options go to Plot Selection where you can enable (X) or disable individual pole figures by clicking on box.
