Machine Learning - Other Types of Graphs Bar, Pareto, Time Series and Pie

In this video we are discussing other types of graphs, there is a bar, perito, time series

and pi. So, at first we are starting with the bar graphs

A bar graph represents the data by using vertical or horizontal bars whose heights or length

represent the respective frequencies of the data. So, here you can consider that college spending for first year students

So, here we are having multiple expenditure heads and the data. the respective expenditures are written there

So now we can express it in the form of this electronics, there試 dormitory decoration, clothing

and shoes. So the respective categories we are writing here and along the x-axis we are plotting the

respective expenses. So these expenses we are having. Now this is the respective graphs we are having

Here these bars are horizontal. But if you swap this x and y levels so now this x is now having the expenditure expenditure heads and y are having the expenditure values In that case the bar diagram is showing the bar graph is showing that the bars are in the

vertical direction. Next one we are going for the Pareto charts. So a Pareto chart is used to represent a frequency distribution for a categorical variable

And the frequencies are displayed by the heights of the vertical bars

which are arranged in order from highest to the lowest. So, that is very important

So, here we are having different state names, and here we are having the state-wise

average cost per mile. So, here the numbers are written. So now they are arranged in the descending order from the highest to the lowest

Now, if we plot the respective graph here, so this graph is known as the perado chart

And this peridot chart will be having the categorical values and the respective numerical

values will be plotted from the largest value to the smallest one Next one we are having the time series graph The time series graph represents data that occurred over a specified period of time

So over a specific period of time we shall be plotting some data

So here you can find that year damage in millions, so 200 to 100 to 105, the respective

values are given in USD, and here you can find that along the X axis we are plotted

the years, along the way axis we are plotting the damage in millions of dollars and here

we are plotting the respective points and then we are just connecting it with some line graph

So here as along the x-axis we are having the time and along way axis will be having

some value so this sort of graph will be known as the time series graph

So let us go for the last graph type we are going to discuss that is a pi graph

So a pi graph is a circle that is divided into sections or wages according to the percentage of frequencies in each category of the distribution So you know that this circle is having 360 degree So that 360 degree will be divided according to that frequency or the percentage of frequency

of these classes. So here we are having the respective class names and here we are having the respective frequencies

and this is a percentage frequency. You know that percentage frequency can be calculated in this way that is 5 into 1

by 25 so we are getting this one as 20 in this way the percentage frequency sum

will be 100 and if I want to calculate the respective degree for each and every

category in that case it will be coming like this that is 5 by 25 into 30 60

degree so here you are going to get a 72 degrees so in this way for all the

categories we have done the degree calculations and accordingly the pie graph

has been drawn. So in this video we have discussed how the different types of graphs can be drawn
