问题 I have an ellipse that I want to solid fill with colors in different sections. To achieve this I'm using arcs patches. I'm currently drawing multiple arcs and using zorder to overlap the appropriate arcs . Main issues are that I cannot solid fill arc patches and they are not neatly filling the ellipse . It would be great if the areas didn't overlap either so I could use transparency parameters. import matplotlib.pyplot as plt import matplotlib as mpl import math fig, ax = plt.subplots(figsize

问题 I need to replace "0" row data in pandas with the previous rows non-zero value IF and ONLY IF, the value in the row following the "0" is non zero. I.e. 101 92 78 0 107 0 0 would become: 101 92 78 78 107 0 0 Any ideas how to do this would be much appreciated :-) Thanks! 回答1: using shift you could do In [608]: df.loc[(df.val == 0) & (df.val.shift(-1) != 0), 'val'] = df.val.shift(1) In [609]: df Out[609]: val 0 101.0 1 92.0 2 78.0 3 78.0 4 107.0 5 0.0 6 0.0 回答2: This is answer is similar to

问题 I wish to fill regions between two lines in Python 3x (I mostly work in v3.7 presently) using data series that share a common scale, but lack mutual x-values. 'fill_between' would be handy but requires common x values for the two y-series matplotlib documentation matplotlib demo data follows: x1 = [0.0, 3.2, 10.2, 15.4, 19.9, 24.2, 27.7, 33.9, 50.7, 67.9, 83.7, 102.0, 105.8, 119.4, 129.3, 140.3, 146.0, 150.2, 158.3, 166.7, 168.6, 171.7, 173.5, 175.3, 184.1, 203.7, 220.2, 221.8, 226.8, 231.9]

问题 When plotting two regression curves using geom_smooth() in ggplot2 , for the fill color, the legend picks the one where the confidence intervals intersect. I do think this behaviour arises when the overlapping area is proportionally bigger that the other, however I find this quite undesired because the reader is capable of deducing that the "darkened" area is the one where the CI intersect. It is IMHO a bit harder or unintuitive to assign the same color for both the curves. How can I correct

问题 Currently I try to write code for calculating the parts of the screen you can see and those who can't because of objects that block light in 2d, like in Among Us: The code should run on a processor with very low specs (at least in 2020), the C64. On such a simple CPU it's not possible to do such complex math fast enough for a game, so I came up with an idea: First of all, I make everything tile based, that makes processing easier and also means that I can just change entire characters or
