[//]: # (werk v2) # Respect lower vertical range limit when rendering graphs key | value ---------- | --- date | 2024-06-07T12:10:25+00:00 version | 2.4.0b1 class | fix edition | cre component | multisite level | 1 compatible | yes When rendering a graph with a vertical range that does not comprise all the data, the lower vertical range limit was not respected. Instead, the rendered lines or areas extended into the area below the graph, potentially covering the time axis labels. As of this werk, rendered lines and areas are cut off at the lower vertical range limit.
