AllowMultipleSelection: Boolean;
The AllowMultipleSelection property determines whether multiple selection is available for legend elements.
Available values:
True. Default value. If a legend element is selected, formatting of the previously selected elements is kept.
False. Only one element can be selected.
Use JSON or the setAllowMultipleSelection method to set the property value and the getAllowMultipleSelection method to get the property value.
Executing the example requires that the HTML page contains the BubbleChart component named bubbleChart (see the Example of Creating the BubbleChart Component section.
// Get value interval legend var legend = bubbleChart.getLegend(); // Set color and transparency of the brush for highlighting legend elements var brush = legend.getHighlightBrush(); brush.setColor("#FFE500"); brush.setOpacity(0.2); legend.setHighlightBrush(brush); // Set color of legend highlighted elements legend.setHighlightItemColor("LightSeaGreen"); // Set mode of highlighting display on click legend.setHoverMode(PP.HoverMode.Click); // Enable legend element highlighting legend.setDoHighlight(true); // Disable multiple selection of legend elements legend.setAllowMultipleSelection(false); // Refresh chart bubbleChart.refresh();
After executing the example the following legend properties were changed: color and transparency of the brush for highlighting legend elements, color of highlighted elements, highlighting display mode on click is set, highlighting is enabled, and multiple selection of legend elements is disabled.
