how to change size of point in ChartJS
提问by Vba_Beg
I'd like to change a size of the point in my chart.
我想更改图表中点的大小。
The point should be as small as possible. Was trying to use
该点应尽可能小。正在尝试使用
pointHoverRadius: 1
But it doesn't work.
但它不起作用。
Thanks in advance,
提前致谢，

You would have to set the pointRadiusproperty to 1as well (so the point becomes small initially), along with the pointHoverRadius(remains small on hover)
您还必须将pointRadius属性设置1为(因此该点最初变小)以及(在悬停时保持小)pointHoverRadius
pointRadius: 1,
pointHoverRadius: 1

It indeed needs to go in the dataset, like so:
它确实需要进入数据集，如下所示：
{
type: 'scatter',
data: {
labels: ['2015', '2016', '2017', '2018', '2019', '2020'],
datasets: [
{
label: 'Cars',
data: [{x:-10,y:0}, {x:0,y:10}, {x:10,y:5}, {x:4,y:8}],
pointRadius: 10,
....
},
{
label: 'Bikes',
data: [{x:10,y:3}, {x:-2,y:6}, {x:9,y:3}, {x:11,y:6}],
pointRadius: 10,
...
}
]
},
options: {
...
}
}
