Hi,

I'm trying to change de selection of Scatter Graph when user click in a 
button, but when I call the setSelection function with the specific row and 
column that I want to select, the following exception is throw:

Cannot read property 'nodeType' of undefined or null reference.

this.chart.setSelection([{
                    row: data.row,
                    column: data.column
                }]);

I checked the row and column values, and it's correct.

I appreciate if someone could help me with this.

Thanks,

Murilo
