How to Annotate Bars in Grouped Barplot in Python? A histogram is basically used to represent data provided in a form of some groups.It is accurate method for the graphical representation of numerical data distribution.It is a type of bar plot where X-axis represents the bin ranges while Y-axis gives information about frequency. One is speed. The following histogram displays the heights on the x-axis and relative frequency on the y-axis. He also rips off an arm to use as a sword. After data is collected, processed, and modeled, the relationships need to be visualized for the conclusions. Frequency polygons are analogous to line graphs, and just as line graphs make continuous data visually easy to interpret, so too do frequency polygons.
