KPG1_LLTRx

Saves a transformation for a data co-ordinate linear or logarithmic plot in the AGI database

Description:

This routine defines the transformations between world and a log10-log10 or log10-linear data co-ordinate system, that has either, neither or both axes with reversed polarity (increasing right to left or top to bottom), and saves the transformation in the AGI database with the current picture.

Invocation

CALL KPG1_LLTRx( XLOG, YLOG, SCALE, OFFSET, STATUS )

Arguments

XLOG = LOGICAL (Given)
If true the x-axis is logarithmic in data co-ordinates, otherwise it is linear.
YLOG = LOGICAL (Given)
If true the y-axis is logarithmic in data co-ordinates, otherwise it is linear.
SCALE( 2 ) = ? (Given)
The scale factors of each linear axis to transform from world co-ordinates to data co-ordinates.
OFFSET( 2 ) = ? (Given)
The offsets of each linear axis at pixel 0 to transform from world co-ordinates to data co-ordinates.
STATUS = INTEGER (Given and Returned)
The global status.
