So we have learned how to draw up a judge and a doughnut jar.
And I have told you that we should.
A white pie charts and donor charts.
Let me add that my point in this we do.
So here's a really pie chart showing the market chart of four different suppliers.
My question to you is can you identify which is the biggest supplier from this graph.
So most people say that supplier B is the biggest one which is this one.
And if you have to estimate the proportion of market share of their supplier probably 40 percent 35
percent or something like that.
So that's the point I'm trying to make.
First it is very difficult to find out which is the biggest supplier.
And secondly it is very difficult to find out what is the actual contribution of each supplier by just
looking at the size of each slice of the pie.
Let me show you the better way of drawing this graph
Do you notice the difference.
The same information which would be depicted using that pie chart is depicted here.
And it is very clear and efficient.
You can see that supply it is actually the biggest supplier instead of supplier B.
When you look at the 3D version of a pie chart one of the issues in a 3D vision is to make it look 3-D.
This part is made smaller to make it look farther.
In fact this slice of the pie is larger than this slice of the pie.
Also maybe by using data labels you could identify which was bigger.
But but this bar chart is making it very easy for our eyes to compare the end point.
So it is making it helpful to not just find out which segment is the largest but also how incrementally
larger each segment is from the other so whenever you're thinking of creating a pie chart take a pause
and ask yourself like always draw a bar chart along with a pie chart and compare which one of these
is conveying your message more clearly.
I am pretty sure that always a bar chart is the graph to go ahead and you will not lose any information
while transforming a pie chart into a bar chart.
The second graph that we learned was a donor jug and this is the chart that you should not use.
As I told you that it is difficult for our eyes to compare these angular distances in a pie chart.
Similarly in this donor chart it is difficult for our eyes to compare these outlines.
Moreover if you have a number of categories or sections in a art it makes it even more difficult.
If you add another category to this that will increase the Italians to another level.
So just as pie chart try to avoid donor charts.
If you have multiple categories go with a bar chart with multiple cities too.
Although we have told you how to draw a pie chart and do not chart when you have the option of drawing
one try to avoid it and draw a bar chart.
If you are given a pie chart and a donor chart and you have to take a decision build on it take extra
caution and look at the data so that your clear which category is contributing homage.
