Pie Symbol Plot Legend

Use the Geochem Map > Point Plots > Pie Plot Legend menu option (CHPIELEG GX) to plot a legend for the Pie symbol plots.

Number of channels	Select assay channel to plot from current database. Any value from 1 to 8 may be selected. Script Parameter: CHROSE.NUMCHAN
Radius (mm)	(Rose and Pie Plots) The radius of all the sector, in mm. The legend plots as a circle, since all the sectors are this radius. Script Parameter: CHROSE.LEGSIZE
Symbol edge colour	Symbol edge colour, 7 colours available "black outline" (default). Script Parameter: CHROSE.COLOR
Text Height (mm)	The height of the channel text labels, in mm. The labels are plotted around the outside edge of the plot. Script Parameter: CHROSE.TXTSIZE
Starting angle	Specify where the first edge of the first plotted pie slice in the Rose or Pie plots begins, measured in degrees counter-clockwise from horizontal (3 o’clock). By default this value is 0.0. Script Parameter: CHROSE.STARTANG (default 0.0)
Bottom left X (mm) Bottom left Y (mm)	The location of the bottom-left corner of the plot, in base view coordinates. Use the Locate button to interactively select this position. Script Parameter: CHROSE.X, CHROSE.Y
Next>	Proceed to define channels.
Finish	Plot the legend. If channels or colours remain to be defined, the appropriate dialog will appear before you can plot.
Locate	Interactively define the location of the bottom-left coordinates of the legend.

If this GX is run from the CHPIE GX, or immediately following, the following parameters will already be set.

Channel X	Select a channel from the drop-down list. All values must be specified. Script Parameter: CHROSE.CHANX (Where X is a value from 1 to 8)
Next>	Proceed to define scaling.
<Back	Return to the main dialog
[Finish]	Plot the legend. If channels or colours remain to be defined, the appropriate dialog will appear before you can plot.

(Channel Name) scaling	The scale value is taken from the "symbol scaling" attribute for the given channel. If this value is not defined, the default scaling defined in the CHROSE GX is used.
Next>	Proceed to define colours.
<Back	Return to the main dialog
[Finish]	Plot the Rose plots. If channels or colours remain to be defined, the appropriate dialog will appear before you can plot.

(Channel Name) colour

Select a colour from the drop-down list. All values must be specified.

Script Parameter: CHROSE.COLX (Where X is a value from 1 to 8)

<Back

Return to the main dialog

[Finish]

Plot the legend. If channels or colours remain to be defined, the appropriate dialog will appear before you can plot.

This GX is designed to be run from the CHPIE GX, but it may be run on its own.
