History

2012-01-20 Steven Lambright - Completed documentation.

2012-07-03 Steven Lambright - Added Meters, Kilometers to the Units enum. References #853.

2014-04-15 Tracie Sucharski - Reset defaults for plots to the following: SolidLine, Width=1, NoSymbols. This is a temporary fix until the defaults can be saved on a user basis. Fixes #2062.

Member Enumeration Documentation

◆ Units

enum Isis::PlotCurve::Units

These are all the possible units for the x or y data in a plot curve.

We want these in order to have type checking when moving curves around - it's theoretically possible to even utilize the right y axis automatically when you put mismatched plot curve y data into the same plot. All of this and more requires knowing your data's units.

Enumerator
Unknown	The data units are not yet known. Please avoid using this if at all possible.
Band	The data is a band number.
CubeDN	The data is a Cube DN value.
Elevation	The data is an elevation (in meters).
Percentage	The data is a percentage (0-100).
PixelNumber	The data is a pixel #. For example, it's the nth pixel along a line.
Meters	The data is in meters. For example, it's the nth meter along a line.
Kilometers	The data is in kilometers. For example, it's the nth kilometer along a line.
Wavelength	The data is a wavelength. This is usually associated with a band and comes from the band bin group.

Member Function Documentation

◆ attachMarkers()

void Isis::PlotCurve::attachMarkers ( )

After attaching this curve to a plot, due to an inheritance/implementation complication with qwt the markers will remain detached until they are recreated.

This forces the markers to be updated immediately.
