Scatter Graph Line Loop

đź“Š Plotly Python

I have about a dozen (x,y) pairs in a Scatter trace using the offline Python API. The “markers” mode behaves as expected, but if I use the “lines+markers” mode, it not only plots a line connecting x-adjacent points as you’d expect, but also a line from the first point to the last. Here’s what the connecting line looks like:

I haven’t found anything so far in the Python API docs that would explain this, so any insight into what could cause this would be welcome.

Occam’s Razor wins again. There was some duplicate data that was apparently looping the trace back. Cleaning out the data cleaned up the graph.
