You can combine different types of charts to form a combination chart. For example one chart can have a combination of area, line, column, etc. It should be kept in mind that series are rendered in the order they appear in data array. As a result, some of the series might overlap others depending on their position in the data Array.
Pie charts and Doughnut charts cannot be combined with any other chart type.Notes
You can combine any kind of chart types except for the following two exceptions:
Here is a combination of line and column chart. Try creating other combinations.
Here is another combination chart with two column, one area and two line charts.
In some cases series overlap one another. It should be kept in mind that series are rendered in the order they appear in data array.
