Plotly: How to reverse axes?

Question

I want to reverse the y-axis of the graph I've obtained for all the over-plots using plotly.graph_objects. I know reversing of the axis can be done using plotly.express. But I would like to know how to reverse the axis using plotly.graph_objects:

Answer 1

You can use:

fig['layout']['yaxis']['autorange'] = "reversed"

and:

fig['layout']['xaxis']['autorange'] = "reversed"

Plot - default axis:

Code:

import plotly.graph_objects as go
import numpy as np

t = np.linspace(0, 5, 200)
y = np.sin(t)

fig = go.Figure(data=go.Scatter(x=t, y=y, mode='markers'))

fig.show()

Plot - reversed x axis:

Plot - reversed y axis:

Code - reversed axes:

import plotly.graph_objects as go
import numpy as np

t = np.linspace(0, 5, 200)
y = np.sin(t)

fig = go.Figure(data=go.Scatter(x=t, y=y, mode='markers'))
fig['layout']['xaxis']['autorange'] = "reversed"
fig['layout']['yaxis']['autorange'] = "reversed"

fig.show()

Awesome, this works for a particular subplot as well. Whereas fig.update_yaxes(autorange="reversed") given in plotly documentation reverses the y axis for all the subplots in a row – Frederickson

Update to 2023, this was the only solution that actually worked. – Endblown

Answer 2

fig.update_yaxes(autorange="reversed", row=2, col=1)

Also works for subplots without changing the order for other plots

As a comment to this answer, when trying this an error is thrown that "row" is not recognized. Was there another setup step for this to work? Perhaps a version that has changed? It doesn't work now. – Endblown

the row and col is for illustrating use when using in a subplot. Leave out altogether if using a single graph. – Jozef

Answer 3

You can also set a range with fixed values by using the interval [hi, low] instead of using [low, hi] where (low < hi). Here are two examples.

import plotly.express
import plotly.subplots.make_subplots

fig = plotly.subplots.make_subplots(1,1)
fig.update_yaxes(range=[hi, low], row=1, col=1) # Reversed y axis because we do not use [0, H]

fig_alternate_example = plotly.express.scatter(... , range_y=(hi, low))
