You can override these for your `Chart` instance by passing a second argument into the `Line` method as an object with the keys you want to override.
You can override these for your `Chart` instance by passing a member `options` into the `Line` method.
For example, we could have a line chart without bezier curves between points by doing the following:
For example, we could have a line chart display without an x axis by doing the following. The config merge is smart enough to handle arrays so that you do not need to specify all axis settings to change one thing.
```javascript
new Chart(ctx).Line(data, {
bezierCurve: false
new Chart(ctx).Line({
data: data,
options: {
xAxes: [{
show: false
}]
}
});
// This will create a chart with all of the default options, merged from the global config,
// and the Line chart defaults, but this particular instance will have `bezierCurve` set to false.
