How to center title in Plotly

In Plotly, you can center the title of a plot by setting the title.x attribute to 0.5 and the title.xref attribute to “paper”.

Here’s an example of how you can center the title of a plot in Plotly:

Use title_x=0.5 with xref=’paper’ and xanchor=’center’—xanchor determines alignment point, not just position value alone.

import plotly.express as px

# Create a sample plot
df = px.data.tips()
fig = px.scatter(df, x="total_bill", y="tip", color="smoker")

# Center the title
fig.update_layout(
    title=dict(
        text="Tips Dataset",
        font=dict(size=24),
        x=0.5,
        xref="paper"
    )
)

# Show the plot
fig.show()

Center title vertically: use title_y with yanchor=’top’ or ‘middle’ – positioning and alignment options for complete title control.

In this example, we use Plotly Express to create a scatter plot of the tips dataset, and then we update the plot layout to center the title. Title attributes: text (string), x/y (0-1 position), xref/yref (‘paper’ or data), xanchor/yanchor (alignment relative to position), font (styling). Finally, we show the plot using the show method of the figure object.
