Creating Combination Charts
Combination charts are similar to multi-series charts, they allow you to plot multiple datasets on the same chart. But an added advantage with using combination charts is that you can also plot multiple chart types on the same chart. For example, you can show the column, line, and area chart on the same chart canvas.
Combination charts can be rendered in either 2D or 3D, can have single or dual y-axes, and can be stacked or multi series in nature.
The combination charts available in the FusionCharts Suite XT are:
-
2D Single Y Combination (Combi 2D)
-
3D Single Y Combination (Combi 3D)
-
2D Dual Y Combination (Combi DY2D)
-
Column 3D + Line Single Y
-
Column 3D + Line Dual Y
-
Stacked Column 2D Line Single Y
-
Stacked Column 3D Line Single Y
-
Stacked Column 3D Line Dual Y
-
Multi Series Stacked Column 2D + Line Dual Y
In this section, you will be shown a how you can create combination charts.
Creating a 2D Single Y Combination Chart(Combi 2D)
A 2D combination chart with a single y-axis looks like this:
In the above chart, we have compared the actual revenue, the projected revenue and the profit earned for each month of the last year. All three metrics have been plotted using different chart types - the actual revenue earned is plotted using a column chart, the projected revenue is plotted using a line chart, and the profit earned is plotted using an area chart.
Using a different chart type for each metric ensures easy interpretation of the data being shown.
The data structure needed to create a 2D combination chart with a single y-axis is given below:
{
"chart": {
"caption": "Actual Revenues, Targeted Revenues & Profits",
"subCaption": "Last year",
"xAxisname": "Month",

}Creating a 2D Dual Y Combination (Combi DY2D)
A 2D combination chart with dual y-axis looks like this:
In the above chart, we have shown a comparison between the revenue, profit, and the profit percentage. The revenue and the profit will be shown as amount in dollars but the profit percentage will require a different unit - percentage. These cannot be plotted on a single y-axis. FusionCharts Suite XT allows you to have two y-axes, a primary y-axis and a secondary y-axis, if you have two data of two different numeric units to plot.
Therefore, we’ve plotted the amount in USD on the primary y-axis (the one on the left) and the profit % on the secondary y-axis (the one on the right).
The data structure needed to create a 2D combination chart with dual y-axes is given below:
{
"chart": {
"caption": "Revenues and Profits",
"subCaption": "For last year",
"xAxisname": "Month",
"pYAxisName": "Amount (In USD)",
