# Setting the Font, Title, Legend Entries, and Axis Titles in Python

How to set the global font, title, legend-entries, and axis-titles in python.

In [1]:
import plotly.graph_objects as go

fig = go.Figure()

x=[0, 1, 2, 3, 4, 5, 6, 7, 8],
y=[0, 1, 2, 3, 4, 5, 6, 7, 8],
name="Name of Trace 1"       # this sets its legend entry
))

x=[0, 1, 2, 3, 4, 5, 6, 7, 8],
y=[1, 0, 3, 2, 5, 4, 7, 6, 8],
name="Name of Trace 2"
))

fig.update_layout(
title="Plot Title",
xaxis_title="x Axis Title",
yaxis_title="y Axis Title",
font=dict(
family="Courier New, monospace",
size=18,
color="#7f7f7f"
)
)

fig.show()


The configuration of the legend is discussed in detail in the Legends page.

### Align Plot Title¶

The following example shows how to align the plot title in layout.title. x sets the x position with respect to xref from "0" (left) to "1" (right), and y sets the y position with respect to yref from "0" (bottom) to "1" (top). Moreover, you can define xanchor to left,right, or center for setting the title's horizontal alignment with respect to its x position, and/or yanchor to top, bottom, or middle for setting the title's vertical alignment with respect to its y position.

import plotly.graph_objects as go

fig = go.Figure(go.Scatter(
y=[3, 1, 4],
x=["Mon", "Tue", "Wed"]))

fig.update_layout(
title={
'text': "Plot Title",
'y':0.9,
'x':0.5,
'xanchor': 'center',
'yanchor': 'top'})

fig.show()
