### gog_series_has_legend ()

    gboolean            gog_series_has_legend               (GogSeries const *series);

`series` : | GogSeries
Returns : | TRUE if the series has a visible legend entry

### gog_series_get_name ()

    GOData *            gog_series_get_name                 (GogSeries const *series);

If `ind` >= 0 attempt to assign the new index. Auto indicies (`is_manual` == FALSE) will not override the current index if it is manual. An `index` < 0, will reset the index to automatic and potentially queue a revaluation of the parent chart's cardinality.
