# Point Style
This sample show how to use the dataset point style in the legend instead of a rectangle to identify each dataset..
```js chart-editor
// <block:actions:2>
const actions = [
{
name: 'Toggle Point Style',
handler(chart) {
chart.options.plugins.legend.labels.usePointStyle = !chart.options.plugins.legend.labels.usePointStyle;
chart.update();
}
},
];
// </block:actions>
// <block:setup:1>
const DATA_COUNT = 7;
const NUMBER_CFG = {count: DATA_COUNT, min: -100, max: 100};
const data = {
labels: Utils.months({count: DATA_COUNT}),
datasets: [
{
label: 'Dataset 1',
data: Utils.numbers(NUMBER_CFG),
fill: false,
borderColor: Utils.CHART_COLORS.red,
backgroundColor: Utils.transparentize(Utils.CHART_COLORS.red, 0.5),
borderWidth: 1,
pointStyle: 'rectRot',
pointRadius: 5,
pointBorderColor: 'rgb(0, 0, 0)'
},
]
};
// </block:setup>
// <block:config:0>
const config = {
type: 'line',
data: data,
options: {
plugins: {
legend: {
labels: {
usePointStyle: true,
},
}
}
}
};
// </block:config>
module.exports = {
actions: actions,
config: config,
};
