QVector<int> DataCurve::d_index_to_row

mutableprivate

Mapping of curve indices to row indices in d_table.

Besides d_start_row and d_end_row, this takes into account rows which had invalid entries in one of the relevant columns the last time convertData() was called. Usually, changes in validity should cause the curve to be updated via updateData(); however, subclasses of DataCurve may depend on more columns than X and Y (in particular, this is true of vector curves); so DataCurve cannot (within the current architecture) compute this mapping on demand and has to store it like this.
