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()
