A JavaScript Mixed Chart or a Combo Chart is a visualization that allows the combination of two or more distinct graphs. The features of each chart are retained on the mixed chart plot. Different scales of measure are present on the mixed chart and with this; it is an ideal plot for presenting data values that are usually difficult to combine because of the significant difference in value ranges. Generally, a combo chart makes it possible to view the relationship, differences, deviations, and anomalies between a different set of data by bringing them on a single plot.
