Hi!
I have 2 related charts and I'm trying to show the tooltips at the same
time once the user's mouse is over any of the charts.
So, I did something like this for the first chart chart_1
google.visualization.events.addListener(this.chart_1, 'onmouseover', (event) =>
{
this.chart_2.setSelection([event])
});
However, unexpected behaviour occurs.
The tooltip of chart_2 does not appear while the mouse is over the chart_1
until
I explicitly click on the chart_2, once I click on it, both tooltips are
synchronized.
Is this expected? Is it a bug?
Any idea?
Thanks!
