Histogram Differences Plotly vs Matplotlib

📊 Plotly Python

Hi All,

Does anyone knows why histograms have different distributions when plotting in python vs matplotlib even when using the same number of bins in each case?
Note: one of the plots contains a scatter-plot bc i’d like to select outliers and display them on a table.

The bin size is clearly not the same on your two example plots.

You also seem to plot different things. The first plot is showing Price returns in $, the other is showing some probability of a return. (How can a return of a product be negative?)

To me it looks like there is something messy about the data you are trying to plot.

same bin 30, and i didn’t change labels (i know, a bit sloppy).

  • If you count the bins between 0 and 0.05, the upper plot has 3 bins, the lower has 8. I thoroughly believe something about your bin size is not correct.
  • The reason I belive your are not plotting the same data is if you look at the counts. On the upper plot, the bin just to the right hand side of 0 holds 11 counts, on the lower plot the bins have somewhere between 18 and 12 counts.
