Mixed-Type Charts

You can combine multiple chart types inside a single <Chart> tag to create mixed-type charts.

Examples

Mixed-Type Chart

This example uses multiple y columns and multiple series types (bar and line)

composable

<Chart data={fda_recalls}>
    <Bar y=voluntary_recalls/>
    <Line y=fda_recalls/>
</Chart>

Because x is the first column in the dataset, an explicit x prop is not required.

This structure also gives you control over the individual series on your chart. For example, if you have a single series running through a component, you can override props specifically for that series. Since the FDA acronym was not fully capitalized above, you can rename that specific series inside the <Line> primitive:

composable-name-override

<Chart data={fda_recalls}>
    <Bar y=voluntary_recalls/>
    <Line y=fda_recalls name="FDA Recalls"/>
</Chart>

Chart <Chart>

<Chart data={query_name}>
    Insert primitives here
</Chart>

  <Line y=sales/>

  <ReferenceArea xMin='2020-03-14' xMax='2020-05-01'/>
</Chart>
