"get_symbol_colors( )" function not working properly for Histogram

[fakemonkeyking]

When creating Histogram plots, the "get_symbol_colors( )" to ask the chart to follow layer style would only return 1 colour legend and the remaining bars are shown black.

To Reproduce
Steps to reproduce the behavior:

1. Categorise a layer'sdata and apply styles to it (number in this case)
2. Plot Histogram
3. For Marker color, click Data Defined Override and click edit
4. type "get_symbol_colors( )" or select it under Data Plotly

The chart only picks up one color and the rest are shown black

Screenshots
This is the histogram with ""get_symbol_colors( )" applied to markers

This is the mapping style and category

• Windows
• 3.28.4-Firenze
• DataPlotly 4.0.3

@ghtmtt I can confirm get_symbol_colors() sadly don't work in QGIS ver. 3.32.3 either. I cross my fingers you'll get the time to have a look at it.
