Detailed Description
Class for drawing fields with colormap.
Implementation of Graph3D. Used in Frame type plots.
Constructor & Destructor Documentation
| FieldGraph::FieldGraph | ( | const ScalarField * | field | ) |
Constructor for plotting ScalarField.
| FieldGraph::FieldGraph | ( | const Geometry * | geom, |
| const VectorField * | field, | ||
| field_type_e | field_type | ||
| ) |
Constructor for plotting a VectorField field in geometry geom.
|

Destructor.
Member Function Documentation
| void FieldGraph::enable | ( | bool | enable | ) |
Enable/disable plot.
|
virtual |
Get bounding box of drawable.
Returns the bounding box of the drawable in array bbox in order xmin, ymin, xmax, ymax.
Reimplemented from Colormap.
|
virtual |
|
virtual |
Plot sample for legend.
Plot graph sample for legend at cairo coordinates x.
Reimplemented from Colormap.
| void FieldGraph::set_stepped_palette | ( | int | steps | ) |
Set logarithmic scale.
Set stepped palette.
If steps is less than or equal to 1 a regular interpolated palette will be used, otherwise steps is used as the number of separate shades in the palette.
