This document provides examples and explanations of different chart types in Power BI, including pie charts, doughnut charts, treemaps, and funnel charts. It demonstrates how to format and limit pie charts, and explains how treemaps and funnel charts display hierarchical and sequential data respectively.

Pie Chart
The purpose of a Pie chart is to illustrate the contribution of different values to a total.
For instance, let's show the different Regions and the percentage of the overall Sales.
Suppose I wanted to subdivide each particular pie (portion) for each individual Region Name.
I want to know what the sales were in Q1, Q2, Q3, Q4 but I want the colours to remain as each individual Region Name. So what I need to do is drag Quarter into Details.
We have now each of pie segments divided up into four.
Note make sure to put Legend ON: Format + Legend ON

Doughnut Chart
A doughnut chart is similar to a pie chart in that it shows the relationship of parts to a whole. The only difference is that the center is blank and allows space for a label or icon.

Pie Chart - Format
How to change the labels styles: Format + Detail Labels ON + Label Style
For example, you can see the Category, or data value, or the percentage of the total,or some combination thereof.
Pie Chart - Limit
For instance, what if you had 20 items? Let's say I have Date - Year into Legend. You see that it gets very crowded very quickly.
Now in some of the other programmes, you can say I want the top 10 to be shown separately and everything else to be grouped together.
That is not yet possible in Power BI.

Treemaps
An alternate way of displaying values which are 100% of a total value is by using the Treemap.
Treemaps display hierarchical data as a set of nested rectangles.
Each level of the hierarchy is represented by a colored rectangle (branch) containing smaller rectangles (leaves).
Power BI bases the size of the space inside each rectangle on the measured value. The rectangles are arranged in size from top left (largest) to bottom right (smallest).
Using a treemap, we have the entire visualisation taken up by each of the region names and we can also drill down to show all of the quarters.
If we move Date into Details: we will have the four quarters grouped together for each Region. So use Details section when you want to subdivide while still keeping the same colour.
What might be very useful is set up drill through. So clicking on any one of the rectangles and getting to a visualisation for that particular area. So for instance, you can drill through to a different page that you have
set up.

Funnel Chart
- shows percentages of the total from top to bottom
- helps you visualize a linear process that has sequential connected stages
- are good if you have got sequential data (So anything which is a linear sequence is a good fit for the funnel charts).
Examples:
Perhaps you are going through various stages, and you want to see:
- how many hours are being spent by labour,
- how many hours are being spent by plumbing or by decorating,
- how much volume of a project you have got.
Formatting - New Section = Conversion Rate Label ON, which shows the percentage difference from the very first item.
