I was trying to create a new visualization using the "Aggregation based \>\> Line Graph". However I encountered a bug where my y-axes legends seems to be duplicating (See axes "N6\_TEMP, N7\_TEMP and N8\_TEMP" in the image below)

Interestingly, the duplication only happens after the 8th y-axes is added. Every subsequent added axes are duplicated.

Hey @Jasper_Tan, you are on 7,12 right? This is a known bug [[Visualizations] Aggregation based bar charts show same bar twice · Issue #95518 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/95518)

This bug happens only for the charts library that was introduced on 7,12. For now you can go to Advanced Settings and turn on the following switch to switch to the old implementation.
