# Grid Configuration
|
|
|
|
This sample shows how to use scriptable grid options for an axis to control styling. In this case, the Y axis grid lines are colored based on their value. In addition, booleans are provided to toggle different parts of the X axis grid visibility.

|
```js chart-editor
|
|
// <block:actions:2>
|

const actions = [

|
handler(chart) {

|
chart.data.datasets.forEach(dataset => {
|
|
dataset.data = Utils.numbers({count: chart.data.labels.length, min: -100, max: 100});
|
|
});
|
|
chart.update();
|
|
}
|
|
