# Mixed Chart Types
With Chart.js, it is possible to create mixed charts that are a combination of two or more different chart types. A common example is a bar chart that also includes a line dataset.
Creating a mixed chart starts with the initialization of a basic chart.
```javascript
var myChart = new Chart(ctx, {
type: 'bar',
data: data,
options: options
});
```
At this point we have a standard bar chart. Now we need to convert one of the datasets to a line dataset.
```javascript
var mixedChart = new Chart(ctx, {
type: 'bar',
data: {
datasets: [{
label: 'Bar Dataset',
data: [10, 20, 30, 40]
}, {
label: 'Line Dataset',
data: [50, 50, 50, 50],
// Changes this dataset to become a line
type: 'line'
}],
labels: ['January', 'February', 'March', 'April']
},
options: options
});
```
At this point we have a chart rendering how we'd like. It's important to note that the default options for a line chart are not merged in this case. Only the options for the default type are merged in. In this case, that means that the default options for a bar chart are merged because that is the type specified by the `type` field.
