控制哪些线有分？ [英] Control which lines have points?

问题描述

使用Chart.js，可以在图形选项中设置是否显示点：

With Chart.js, you can set in the options of the graph to show points or not:

pointDot: true,

我有一个包含三个静态线和一个显示一些波动的线的图形。我希望直线上没有点，但波动线表示这些点。线上是否有可以将磅值设置为零的设置？

I have a graph with three static lines and one line that shows some fluctuations. I'd like the straight lines not to have points but the fluctuation line show the points. Is there a setting somewhere on the line that I can set the point size to nothing?

**编辑**

每一行都是其自己的数据集，配置如下：

Each line is its own set of data configured like this:

 datasets: [
    {
        label: "Cycle Time Per Last Piece",
        strokeColor: "red",
        fillColor: "red",
        pointHighlightFill: "red",
        data: [@foreach (var item in Model.DataPoints) {
        @(Model.ExpectedCycleTimePerPart * 1.20M)@:,
             }]
    },
    {
        label: "Expected Cycle Time Per Part",
        strokeColor: "black",
        pointHighlightFill: "black",
        data: [@foreach (var item in Model.DataPoints) {
        @Model.ExpectedCycleTimePerPart@:,
             }]
     }

推荐答案

pointDot 选项驱动显示属性，因此您可以执行以下操作

The pointDot option drives the display property, so you can do something like

myChart.datasets[0].points[2].display = false;

其中myChart是您的图表对象。

where myChart is your chart object.
