Fitting a curve and finding knee for a HISTOGRAM












0














I have a decreasing histogram which shows the counts of a metric starting from 1 with a very high peak there and decreasing constantly till zero at around 15. I want to find the "knee"/"elbow" to the curve of this decrease, but most answers here are for scatter plots. I know I can hackingly turn my histogram to a scatter plot, but more neatly, how can I fit a curve to a histogram and find parameters related to that curve? Thanks.



I work with pandas and I mainly plot with plotly.

  • I'm not even sure what to share because I havent done anything as far as fitting goes. I'm asking HOW to do it because I have no idea. In regards to the first comment, the raw data is confidential. I can share the histogram but its basically a concave decreasing histogram plot, so pick your generic one.... I just wanna know how one can fit a curve to a given histogram
