    MB := MetabaseClass.Active;
    // Get express report
    Express := MB.ItemById("EXPRESS").Edit As IEaxAnalyzer;
    // Get bubble chart
    BC := Express.BubbleChart.BubbleChart;
    //Enable displaying of bubble movement history
    BC.ShowBubbleHistory := True;
    // Enable displaying of year tooltips
    BC.ShowBubbleHistoryLabels := True;
    // History is displayed on the mouse click on the bubble
    BC.ShowHistoryMode := VisualizatorHistoryModeEnum.Click;
    // Disable displaying of history on moving to the other year
    If BC.ShowHistoryPreviousStepsOnly Then
        BC.ShowHistoryPreviousStepsOnly := False;
    End If;
