overridevirtual |
returns true if the given column is used by the graph
This virtual function indicates whether a given column is used by this graph. Override this function in your derived graphs to indicate to JKQTPlotter / JKQTBasePlotter , which columns from the internal JKQTPDatastore are actually used. This information can be used e.g. for graph-specific data-export.
Reimplemented from JKQTPGraph.
