Cannot Export to CSV if series is not selected -> Possible breaking change between 3.35.3 and 3.35.4?

[tchari]

Description

It looks like there was some change between 3.35.3 and 3.35.4 that made it so exporting a line chart via CSV after deselecting a series throws a Type Error.

Steps to Reproduce

1. Go to https://codesandbox.io/s/react-apex-chart-export-bug-rry6xp
2. Check apexchart is on version 3.35.3
3. Uncheck Series 2
4. Export as CSV -> Success!
5. Switch apexchart version to 3.34.4
6. Uncheck Series 2
7. Export as CSV -> Sadness :(

Expected Behavior

A CSV, excluding the unselected series, is downloaded

Actual Behavior

Type Error: Cannot read properties of undefined (reading 'y') is thrown
