Header: PP.Ui.RatingChartHeader;
The Header method determines rating chart header row.
Use JSON or the setHeader method to set the property value and the getHeader method to get the property value.
Executing the example requires that the page contains the RatingChart component named ratingChart (see Example of Creating the RatingChart Component). Get width of rating chart column headers, enable the last column to overlay the next column if there is no sufficient place and redraw the header row:
// Get header string header = ratingChart.getHeader(); // Get header width of column with data series numbers header.getVisibleIndexColumnWidth(); // Get header width of column for data series position change header.getVisibleMoveColumnWidth(); // Get header width of column with data series names header.getVisibleNameColumnWidth(); // Get header width of the first column with data series values header.getVisibleDataColumnWidth(0); // Get header width of the second column with data series values header.getVisibleDataColumnWidth(1); // Disable temporarily rating chart redrawing header.getChart().beginUpdate(); // Enable the last column with text to overlap the next column if there is not enough space header.setExpandLastColumn(true); // Redraw header row header.draw(); // Refresh rating chart header.getChart().endUpdate();
After executing the example the last column with text will overlay the next column if there is no sufficient place, the console displays width of column headers, header row will be redrawn.
