Null points have a poor performance

[B-o-s-s-e]

Hello everyone,

I have been using Apexcharts for a while now and I am very excited about it. In my last project I wanted to process a few more data points in a line chart with 2 axis. To be exact 3 series on each axis with 1440 data points each.
My whole UI was blocking and it took me a while to figure out what the problem was.

When I add series with zero values the chart becomes extremely slow. Zooming takes 1-2 seconds and my whole UI blocks for a while. When I filter out the null values, the line chart is lightning fast. However, other problems follow from this.
Without null values I have:

• irregular time series and thus problems with the shared tooltip
• a wrong display of data gaps, by connecting the gaps
• not working enabledOnSeries tooltip

I have found several issues with this topic. I'll link 2 relevant ones. In the comments I could read out that the problem also occurs with far fewer data points.

Do you have any tips on how I can get around this? Or an approach where I can start to fix this?
Is anyone working to fix this? 🫣
