myimagelib.myImageLib.xy_bin

myimagelib.myImageLib.xy_bin(xo, yo, n=100, mode='log', bins=None)

Bin x, y data on log or linear scale. This is used when the data is too dense to be plotted directly. The function will bin the data and return the means in each bin.

Parameters:

  • xo – input x

  • yo – input y

  • n – points after binning

  • mode – "lin" or "log", scale to bin the data

  • bins – set the bins to bin data together

Returns:

binned x, and mean y in the bins.

Return type:

2-tuple of array-likes

>>> from myimagelib import xy_bin
>>> x, y = xy_bin(xo, yo, n=100)
>>> x, y = xy_bin(xo, yo, n=100, mode='lin')
>>> x, y = xy_bin(xo, yo, bins=np.linspace(0, 100)')

Edit

  • Nov 04, 2020 – Change function name to xy_bin, to incorporate the mode parameter, so that the function can do both log space binning and linear space binning.

  • Nov 17, 2020 – add bins kwarg, allow user to enter custom bins.

  • Dec 16, 2021 – fix divided by 0 issue.

  • Nov 14, 2022 – Move from corrLib to myImageLib.

  • Apr 01, 2025 – Remove nan before binning, to avoid all-nan yb.
