charts_common/lib/src/chart/common/behavior/legend/series_legend.dart /// Only keep data for a series on the chart by [seriesId]. /// /// The other entries in the legend for this series will be grayed out to indicate /// that they are hidden. @protected void onlyKeepSeries(String seriesId) { if (!isSeriesAlwaysVisible(seriesId)) { _allSeries?.forEach((element) => _hiddenSeriesList.add(element)); _hiddenSeriesList.remove(seriesId); } }

It can be used for the long press. When user long press the legend, only the clicked ones are kept. And other legends are greyed out.
