Markers are cut off at edge of ternary plot area

[vaiotite]

Some makers at edge of ternary plot area are cut off.
Wondering if it is possible that markers appear without cutting off.

#install packeges
import plotly.graph_objects as go
import plotly.express as px
from plotly.validators.scatter.marker import SymbolValidator
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

#input CSV data
df = pd.read_csv('Carbonate_100.csv', skiprows=1, index_col=None, names=('Type', '#Ca','#Mn','#Mg'))

# ternary plot by px
fig = px.scatter_ternary(df, 
                         a="#Ca",
                         b="#Mn", 
                         c="#Mg", 
                         color="Type",
                         symbol="Type")

#graph adjustment
fig.update_ternaries(sum=100,
                     aaxis_min=80,
                     baxis_min=0, 
                     caxis_min=0,
                     aaxis_title_font_size=24, aaxis_tickfont_size=16,
                     baxis_title_font_size=24, baxis_tickfont_size=16,
                     caxis_title_font_size=24, caxis_tickfont_size=16)
fig.update_traces(marker=dict(size=20,
                             opacity=0.5,
                             line=dict(width=1,color='#000000')))
fig.update_layout(legend=dict(xanchor="left",
                              yanchor="bottom",
                              x=0.25,
                              y=0.7,
                              orientation='v',
                              font_size=16,
                              bgcolor="white",
                              bordercolor="black",
                              borderwidth=1)
                 )                             
fig.update_layout(margin=dict(b=50,r=50),
                 xaxis_side="top", height=400, width=900)

Using the code above, I got such ternary plot.

Some markers on the edges appear to be partially missing. But, I'd like to display the entire markers.

Thanks

You want fig.update_traces(cliponaxis=False) https://plotly.com/python/reference/scatterternary/#scatterternary-cliponaxis
