# JavaScript Combination Chart - Visualize and Compare Data Sets

## Overview

JavaScript Combination Chart combines two or more chart types into a single chart to compare different data sets. Supports zooming, panning, tooltip, trackball, and selection.

## Combination of line, area, and column chart

You can create multiple series of different types in the same chart. Legend and tooltip for the series make it more readable.

## Pareto chart

Pareto chart is the combination of line and column chart. The column represents data in the descending order, whereas the line chart represents the cumulative value of the data.

You can combine Candle with line or column chart to show additional parameters in financial analysis. For example, volume of the stock can be viewed with the help of column chart.
