This is my first blog. When I was trying to explore new charts, I came up with this interesting Butterfly Chart. Here I am going to create a Butterfly Chart by combining two Bar Charts.
Introduction-
What is Butterfly Chart?
A butterfly chart in Tableau is a kind of bar chart used to compare two data sets at a time. This chart plots the data as two horizontal bars with the same X-axis in the center, this kind of bar chart looks like the butterfly wings. Bar chart need to reverse in this case to make it like butterfly.
This is actually useful for when you are comparing something like the population of Country, State, City. For Example-Compare male gender population and female gender population of the Country, Compares previous year sales and current year sales for the same product as well as for two different products.
This Butterfly Chart in Tableau is easy to design. Now we are going to make Butterfly Chart.
