set_preferences(list);
set_preferences(string);
set_preferences(object);

Description

The set_preferences command sets the specified preference to the supplied value. The new setting does not affect the attributes of existing objects and data, only new ones created after the call to set_preferences. The argument may be:

• list - pairs consisting of a string specifying the attribute followed by a value, e.g. ['point.color','red','point.size',3] .
• string - string containing a single attribute/value entry, e.g. 'point.fill=false' .
• object - an attribute object containing the appropriate attributes with desired settings.

When using an object, only members not set to "NULL" are used to update preferences.

The save_preferences and load_preferences commands may be used to save and reload ChIPS preferences, respectively.

The following attribute objects are supported:

• ChipsWindow
• ChipsFrame
• ChipsPlot
• ChipsAxis
• ChipsSymbol
• ChipsCurve
• ChipsHistogram
• ChipsContour
• ChipsLabel
• ChipsLine
• ChipsPoint
• ChipsRegion
• ChipsExport
• ChipsPreferences

The following tables give the preferences for each supported object, listed in the same object order.
