Bar Graph
A bar chart, sometimes referred to as a horizontal column chart, is well-liked for a reason: it swiftly visualises data
sets and is easy on the eyes. You can rapidly determine which bar is the highest or lowest as well as the incremental
changes between bars. For example:
Food Pizza Pasta Dosa Chowmein Burger Momos
People 35 30 5 25 40 15
Histogram
A form of bar graph. It is a visualisation of several outcomes organised into columns along the x-axis. The y-axis of the
same histogram represents the number count or multiple occurrences in the data for each column. It is the simplest
method for visualising data distributions. For example:
Weights (in kg) Frequency (Number of students)
20-25 4
26-30 10
31-35 8
36-40 4
Frequency Bins
In the frequency domain, the intervals between samples are known as frequency bins. You have 100 points
between [0–100] Hz, for example, if your sample rate is 100 Hz and your FFT size (number of bins) is 100.
As a result, the full 100 Hz range is divided into 100 intervals, such as 0–1 Hz, 1–2 Hz, and so on. Each of these little
intervals, let's say 0–1 Hz, is a frequency bin.
