How many leads did we receive each month between January and August? How many of these leads resulted in potential opportunities? What is the leads to opportunities ratio? The line chart above answers these questions by comparing trends of two related variables and visualizes percentage ration between them.

The chart plots periodic intervals (months in this example) on X-axis and numeric values corresponding to the two variables (leads and opportunities in this example) on primary Y-axis. The percentage ratio between the two variables in plotted on secondary Y-axis.

The two variables are presented using different colors and distinct connected markers for each period, with data value labels for easy visual distinction and better readability.

Ratio between the two variables being the key highlight point, is presented using bold and bright colored circles with percentage values placed inside them.

With a quick glance at this data presentation, audience can see that both leads and opportunities are showing an increasing trend with an average lead – opportunity ratio of about of 23%.

This data visualization chart is extremely useful for monthly report and KPI dashboard.

KPI Target Example: Lead – Opportunity Ration > 25%
