The Combo chart is a custom symbol included in Vision Library+, that combines the features of two charts like a Line chart and Bar chart. It allows you to show the values of one category as a line and another category as a bar. In the Combo chart, the data is divided into parts called series – the same function that color serves in other chart types. Each series is represented by bars or a line.

You can use a Combo chart to plot multiple data sets on one graph. It’s a great way to prove or disprove a trend or identify outliers as it allows you to compare two variables that have different magnitudes and scales of measurement. You can easily compare measure values that are otherwise difficult to combine like projected sales vs. actual sales.

The chart highlights the differences in data with the visual combination of two different chart types. Your audience will understand this simple visualisation at a glance and make pertinent decisions from the data.

If you’re short of space on your dashboard, the Combo chart is a good choice as it can also save space.

The main advantage of the Combo chart is that you can display multiple measures with different scales. Whereas, one disadvantage is that you can only display one dimension at a time.
