Example

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 interval record format with both borders
legend.setBetweenFormat("from {0:0} to {1:0}");
// Set interval record format with the left border
legend.setGreaterFormat("greater than {0:0}");
// Set interval record format with the right border
legend.setLessFormat("less than {0:0}");
/*
Set position of element corresponding to absent data
in visualizer before other elements
*/
legend.setNoDataPosition(PP.Ui.NoDataPosition.Before);
legend.ItemHovered.add(
    function () {
        tbubbleChart.refresh();
    
);

After executing the example the following legend properties were changed: interval record format with right, left, and both borders, position and text of the element corresponding to absent data in visualizer. These changes will be displayed on hovering a cursor on the legend element.
