How to offset a line relative to another

Community Support
1

Hi - I have two (or more) lines that have very similar y-values - for visual purposes I want to shift one by a little bit. (and I don’t want to change the data - in other words, I don’t want to add y_shift to each point in the 2nd line).

Here is how I would do it in matplotlib

http://matplotlib.org/users/transforms_tutorial.html

Another way to think about this is two lines plotted on two different axes, overlaid on the same figure, but each one occupies a slightly different physical part of the figure.

In plotly, this is:

  • domain (list)
    default: [0, 1]
    Sets the domain of this axis (in plot fraction).
    Each dict has one or more of the keys listed below.

Thanks!

The next release should have a CustomJSTransform that would make this simple to do:

  CustomJSTransform · Issue #5015 · bokeh/bokeh · GitHub

In the mean time, you'd have to write your own Transform type as a custom extension:

In plotly, this is:
Single-page reference in Python
  • domain (list)

Sets the domain of this axis (in plot fraction).
