Minimize width of rug section

📊 Plotly Python
1

I’m using the option marginal_y = "rug" in px.scatter() and I like it a lot. It only takes up a bit too much space / width. Is there a possibility to reduce the width of the rug section next to the plot?

Hi @DeLaRiva, this is related to the xaxis domains. Take this example with two “rugs”:

import plotly.express as px
df = px.data.iris()
fig = px.scatter(
    df, 
    x="sepal_length", 
    y="sepal_width", 
    marginal_x="histogram", 
    marginal_y="rug"
)
fig.show()

newplot (13)
newplot (13)1002×360 15.9 KB

Changing the xaxis domains of each xaxis:

fig.update_layout(
    xaxis={'domain': [0.0,0.95]}, 
    xaxis2={'domain': [0.96,1.0]},
    xaxis3={'domain': [0.0,0.95]}
)

creates:

newplot (14)

Perfect, thanks a lot!

Could you please also explain the values? I mean what do the two values inside the actually do?

An extract form the documents:

domain
Code: fig.update_xaxes(domain=list(...))
Type: list
Default: [0, 1]
Sets the domain of this axis (in plot fraction).

Basically (from my understanding):

  • first float in the list: start of corresponding axis
  • second float in the list: end of corresponding axis

in this case the main axis (xaxis) starts at 0% (left) and takes 95% of the plot, the second axis starts at 96% and ends at 100%. That’s the reason for the gap you see between main plot and right hand side rug.
