Member Function Documentation

void FieldGraph::enable ( bool  enable)

Enable/disable plot.

virtual void FieldGraph::get_bbox ( double  bbox[4]) [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 void FieldGraph::plot ( cairo_t *  cairo,
const Coordmapper cm,
const double  range[4] 
) [virtual]

Plot graph with cairo.

Plot the graph using cairo and coordinate mapper cm. The visible range of plot is given in array range in order xmin, ymin, xmax, ymax. The graph should be able to handle any range values. Also min > max.

Called by Frame during drawing.

Reimplemented from Colormap.

virtual void FieldGraph::plot_sample ( cairo_t *  cairo,
double  x,
double  y,
double  width,
double  height 
) [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.
