hello, are there any improvements on this?

I'm having a similar issue .... I'm temporarily overriding null values to zero to try and get things moving, but having null represented correctly would be very useful.

Searching past issues I see that this has been reported before (https://github.com/apexcharts/apexcharts.js/issues/1778), but that issue was automatically closed without any resolution.

Finding the same here too.

Please label this with high-priority. Love this lib but this makes it unusable :(

[trandaison]

I have to switch to https://github.com/leeoniya/uPlot library to get through this issue :(

+1 for this issue. Was already having to do a loop through all my data and checking for null values and replacing thing with 0 solved my performance issues.

[trandaison]

@davenportw 0 values is different from null values. Unfortunately, in some cases, it can't be replaced.

Confirm, this is a big issue

Love the plugin but can confirm as well this ia a big issue and possible deal breaker.

Any ETA for when this will, hopefully, get addressed?
