Hi,
we have a small issue with Highcharts tooltip when series data are updated every two seconds.
When user moves mouse over the chart, tooltip is visible next to the cursor correctly - it's shared tooltip, so both series are included in the tooltip data. But after two seconds when one serie is updated with use of setData() method, first and sometime also second point happen.
1) Tooltip is moved from the cursor position to some "default" position near the axis.
2) Shared tooltip is showing only those trend data, which was not updated. The second trend data are missing completely. User has to move the cursor to see both series data inside tooltip again.
Have you ever seen this behavior? How can we fix that? Thanks a lot.
Best regards,
David
