Chanbe label font size on paracoords

📊 Plotly Python
1

I have been searching unsuccessfully for the method to increase the font sizes of labels on each pracoord axis.

I tried this:
“”"

Customize the label font

fig.update_layout(
parcoords=dict(
labelfont=dict(
family=“Arial”,
size=14,
color=“red”
)
)
)“”"

with no luck. Suggestions greatly appreciated.

Hi @wayneking517 ,

Welcome to the forum!

The labelfont attribute does not belong to layout, but it belongs to trace.
You can use fig.update_traces, instead of using fig.update_layout.

fig.update_traces( 
        labelfont={
               'size': 14, 
                'family': 'Arial',
                'color':"red"
        }
)
