Creating a Step Line Chart
A step line chart is used to visualize trends for a particular event which is not continuous in nature. For a given set of data, a step line chart enables you to compare the magnitude and change in values at different points of the same series. It also helps you discern the intermittent pattern of the trend at the same time.
In this section, you will be shown how you can create a simple step line chart.
As an example, we will create a step line chart to compare the revenue earned with the expenses incurred for the last year.
The step line chart thus created looks like this:
