In this tutorial we are going to start with monthly sales data for the imaginary store, captured in Microsoft Excel table, and see if there is any correlation between monthly sales and outdoor temperature. Our goal is to find out if people shop less during the winter month, when the weather is colder and if change in sales can be explained by changes in outdoor temperature. To do this task we will be creating Microsoft Excel Combo Chart with secondary Axis.
We will look at the sales data for imaginary store in Wisconsin, USA. There are fewer sales during the winter month. Our goal is to answer the question – is there a correlation between Sales Volume and Outdoor temperature? Are there fewer people shopping in the winter month?
We will build Excel Combo Graph to look at the data visually to find ou. And then create a awesome graph with multiple axis, which clearly shows the pattern? This quick tutorial will help you accomplish your goal.
Our initial set of data consists of monthly sales in one column and Average outdoor temperature for the same month in another column. Our combo chart will consists of 2 charts – Bar chart which would represent monthly sales line chart would display average outdoor temperature. We will also add make line chart more professionally looking by adding markers and 3d animation effect. In the end we will also attempt to answer business questions: can we create a correlation between monthly sales and outdoor temperature?
