void gog_plot_get_cardinality (GogPlot *plot, unsigned *full, unsigned *visible);
Return the number of logical elements in the plot.
See gog_chart_get_cardinality
.
full
and visible
may be NULL.

placeholder for visible cardinality |
void gog_plot_update_cardinality (GogPlot *plot, int index_num);
Update cardinality and cache result. See gog_chart_get_cardinality
.

GSList const * gog_plot_get_series (GogPlot const *plot);
|
GogPlot |
Returns : |
A list of the series in plot . Do not modify or free the list.
|
GOData * gog_plot_get_axis_bounds (GogPlot *plot, GogAxisType axis, GogPlotBoundInfo *bounds);
Queries plot
for its axis preferences for axis
and stores the results in
bounds
. All elements of bounds
are initialized to sane values before the
query _EXCEPT_ ::fmt. The caller is responsible for initializing it. This
is done so that once on plot has selected a format the others need not do
the lookup too if so desired.
Caller is responsible for unrefing ::fmt.
