Point disappearing after hover

[matiastucci]

Bug report

I have a line chart with a few points but only 2 with actual data (price). When I hover the first one and then move the pointer to the next one, the first one disappears and only appears again if I move the cursor near the area where it was.

Any updates on this issue - i stumpled upon this issue today.

I really like this component and i prefer using ApexCharts over ChartJS - but if there is no fix for this i need to back......

EDIT:

Found this example https://apexcharts.com/vue-chart-demos/line-charts/null-values/ that seems to NOT be affected by this issue - is this an older version or something?

Now it does. Must have been updated to include the bug at some point during the last 1½ years.
Can't someone look at this, with it being high-priority and all?

It seems to be caused by moveMarkers() in src/modules/tooltip/Position.js that assumes that if w.globals.markers.size[i] isn't above zero then it can just move around a dynamic marker on index 0. But in this case there are markers so I think it ends up moving around the first marker instead of a dynamic marker.

I have worked around it by setting my marker size to 0.0001 but it is a bit costly.

This appears to be the same bug as #3641
