Using Seaborn, we can do that in a few ways. One simple improvement is to overlay individual observations (datapoints) beside the standard bar-plot format, typically with some degree of randomized jitter to improve visibility (). You can also see how greatly distributions for different groups overlap. Boxplots should not be confused with the candlestick charts, although they can be visually similar. The function subplot create a figure and a set of subplots. The dark line inside the box represents the median. In this article we would understand the multi-variate approach for outlier detection and then finally the outlier treatment methods.

To calculate the Gradient: Have a play (drag the points): The line is steeper, and so the Gradient is larger. We are able to see that there is a slight increase in resell price for certain sizes above 14. Next step is to “bin” the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. But did you know that you could also plot a DataFrame using pandas? You can certainly do that. The matplotlib provides a context, one in which one or more plots can be drawn before the image is shown or saved to file. Multiple axes and minor tick marks.
