After importing data into the Data Manager, you can display the data using the Insert
Visualization dialog. See “Inserting Visualizations” on page 57 for details.
Importing Graphic Objects
You can import graphic objects into your iTool using the Visualization pull-down
menu on the Insert Visualization window. Select IDL Graphics Object and then
import your variable from the Data Manager into the Graphics Object field and
select Insert.
When importing graphic objects into an iTool it is important to remember:
• If the object hierarchy being inserted as a graphic object does not have the
REGISTER_PROPERTIES keyword set, then no properties will be available
in your iTool when the object is visualized.
If the object hierarchy being inserted as a graphic object includes an image object,
rotation may not behave as expected. For more information on image objects and
their behavior, see “Transformations of IDLgrImage Objects” (Chapter 31, IDL
Reference Guide).
Parameter Data and the Command Line
Parameter data can often be entered at the IDL command line in IDL when creating
an iTool. Consider the following example:
1. At the IDL Command Line, enter the following:
myPlotData = RANDOMU(seed, 30)
iPlot, myPlotData
