Laravel 8 ConsoleTvs / Charts 7 实现 Chartjs 选项

Question

我目前正在更新 ConsoleTvs / 图表 6 到 7。图表正在呈现预期数据。
图表未根据图例point style 圆的任何集合options 对象键、padding 前 50 位、显示“y”和“x”轴labelString、不显示gridlines、定位@ 987654326@ 以粗体和绿色结尾，开始偏移：

        const chart = new Chartisan({
            el: '#test_chart',
            url: "@chart('test_chart_route')",
            hooks: new ChartisanHooks()
            .colors()
            .datasets(
                [
                    { type: 'line', fill: false, borderColor: '#329865', backgroundColor: '#329865' }, 
                    { type: 'line', fill: false, borderColor: '#1e5b3c', backgroundColor: '#1e5b3c' },

                                    return (value != '' && value !== undefined) ? Math.round(value * 100) / 100 : value;
                                },
                                anchor: 'end',
                                align: 'start',
                                display: 'auto',
                                clamp: false
                            }
                        }
                    }
        });

我也尝试使用 ChartisanHooks().options({...options...}) 方法，但设置选项没有变化。

谁能告诉我正确的方向？

Answer 1

您没有使用options 挂钩，而是将options 定义为属性。你应该使用.options({ ... })，而不是options: { ... }。

options 钩子对我不起作用，也许我使用了一个过时的 Chartisan 库。根据Custom Hooks，也可以将options合并到图表中，如下：

.custom(function({ data, merge }) {
   return merge(data, {
     options: {
       ...
     }
   }),
})

请在下面查看您修改后的可运行代码，看看它如何与merge 函数一起使用。

const chart = new Chartisan({
  el: '#test_chart',
  data: {
    "chart": {
      "labels": ["First", "Second", "Third"]
    },
    "datasets": [{
        "name": "Sample 1",
        "values": [10, 3, 7]
      },
      {
        "name": "Sample 2",
        "values": [1, 6, 2]
      }
    ]
  },
  hooks: new ChartisanHooks()
    .colors()
    .datasets(
      [{
          type: 'line',
          fill: false,
          borderColor: '#329865',
          backgroundColor: '#329865'
        },
        {
          type: 'line',
          fill: false,
          borderColor: '#1e5b3c',
          backgroundColor: '#1e5b3c'
        }
      ]
    )
    .custom(function({ data, merge }) {
