I have a line chart where I only want the end of the line to be labeled. To do that, I’m using add_scatter() as shown in this stack overflow post. When using hovermode="x", how do I remove the tooltip only for the added trace?
# imports
import pandas as pd
import plotly.express as px
# data
df = px.data.stocks()
df = df.drop('AMZN', axis = 1)
colors = px.colors.qualitative.T10
# plotly
fig = px.line(df,
x = 'date',
y = [c for c in df.columns if c != 'date'],
template = 'plotly_dark',
color_discrete_sequence = colors,
title = 'Stocks',
)
# move legend
fig.layout.legend.x = -0.3
# add traces for annotations and text for end of lines
for i, d in enumerate(fig.data):
fig.add_scatter(x=[d.x[-1]], y = [d.y[-1]],
mode = 'markers+text',
text = d.y[-1],
textfont = dict(color=d.line.color),
textposition='middle right',
marker = dict(color = d.line.color, size = 12),
legendgroup = d.name,
showlegend=False)
fig.update_layout(hovermode="x")
fig.show()
I specifically want to use hovermode="x" so that all trace values are displayed and sorted, but only for the original lines, not the line-end marks.
In add_scatter() I’ve tried some things like hovermode=False and hovertemplate="" but I don’t believe these work with the add trace methods.
Also, the text is cut off at the end of the lines. Is there a way to prevent that?
