In this Article we will learn to create Excel chart with single x axis but two different ranges.

Let us create a simple chart having 2 types of data like day density (range 0 to 20) and percentages (0 to 100%) like below:

Now let us try to create a simple graph from the same. A simple 2d column chart will look like this:

2d column chart

The issue with this chart is that the percentages are treated as decimals and have very low values r columns displayed which are not visible at all.

Let us handle it by creating the secondary axis as follows. Right click on the graph and click change chart type:
