Main features
In this section some of the principal features of GRAFFER are listed.
• Plot a arbitrary number of X-Y plots on a single set of axes (there may be two alternate Y
scales).
• Data for each plot can be:
– Read from a file
– Taken from IDL variables (normally at the $MAIN$ program level only)
– Entered with a data editor
– Entered with the mouse
• Functions can be plotted, including doing basic fits to existing data plots.
• Contour or “image” display of Z vs. X & Y (data or function).
• Easy to change plot limits, log/linear scaling and other axis options.
• Time labelling of axes.
• A secondary Y-axis may be used to allow the overlay of plots with substantially different scales
but the same independent variable.
• Wide range of display styles for individual traces.
• Generate Postscript or EPS version of plot.
• Combining or re-ordering of traces within GRAFFER.
• All possible combinations of error bars and limits are available.
• Save plot to a file for future additions or modification.
• Add a key or legend.
• For X-windows use the IDL RESOURCE="Graffer" key to allow user-customisation of
colours.
