Proportional Symbol Legend
Use the Proportional Symbol Legend option (PROPSYMBLEG GX) from the Map Tools > Symbols menu or from the Geochem Map > Point Plots menu to place a legend describing the proportional symbol scheme on your map.
The option is also available with the Grav/Mag Interpretation extension under the menu Euler 3D > Plot Solution Symbols (PROPSYMBLEG GX).

|
Title for legend (Optional) |
Title for the legend (optional) Script Parameter: PROPSYMBLEG.TITLE |
|
Subtitle for legend (Optional) |
Width of the legend box in map units (optional) Script Parameter: PROPSYMBLEG.SUBTITLE |
|
X Position (mm) |
Location of the bottom left corner of the legend in the X-axis. Script Parameter: PROPSYMBLEG.X |
|
Y Position (mm) |
Location of the bottom left corner of the legend in the Y-axis. Script Parameter: PROPSYMBLEG.Y |
|
Font size |
The font size in map units. Script Parameter: PROPSYMBLEG.FONTSIZE |
|
Zero base level (data units) |
Zero base level (data units). This value is subtracted from the data value in the size channel, before the scaling factor is applied. Values less than or equal to the base level are not plotted. Script Parameter: PROPSYMB.BASE |
|
Scale factor (data units/mm) |
Script Parameter: PROPSYMB.SCALE |
|
Number of symbols |
The number of different sized symbols to plot. Script Parameter: PROPSYMBLEG.NSYMBOLS |
|
Smallest value plotted |
The smallest valued symbol. The symbols form a linear series, starting at this value, and increasing by the increment. Script Parameter: PROPSYMBLEG.START |
|
Increment in values plotted |
Increment in the data value from symbol to symbol. Script Parameter: PROPSYMBLEG.INCREMENT |
|
Symbol |
Set the symbol parameters. Defaults are taken from the PROPSYMB GX values. |
Application Notes
The Legend plots the symbols on the left, with the corresponding data values on the right. The spacing adjusts to the largest symbol plotted.
Default values are set from both the PROPSYMB GX (Proportional symbol plot) and the CLASYMB2 GX (Colour Symbols and Proportional Scaling).
