vaadin柱状图中是否存在多个类别？

Question

我正在尝试构建一个图表，如下所示：

使用angular2的vaadin-charts，除了现在我有两种颜色，因为我正在比较两个不同的源。我已经正确地显示了月份，但我不知道如何将月份划分为季度。

​

​

https://vaadin.com/docs/-/part/charts/webcomponents-api/charts-configuration.html#charts.configuration.axes.categories

这是我到目前为止所得到的：

<vaadin-column-chart>
    <chart-title>Distributions</chart-title>
    <x-axis>
        <categories>Jan, Feb, Mar, Apr, May, Jun</categories>
    </x-axis>
    <y-axis>
      <title>Value</title>
    </y-axis>
    <data-series name="exponential" [data]="exponential">
    </data-series>

    <data-series name="incremental" [data]="incremental">
    </data-series>
  </vaadin-column-chart>

Answer 1

使用，您可以这样做：

​

/* ==================================================||
 These can all be data-binded in a polymer app
 Example: <highcharts-chart id='chart' type="column" title="Distributions" x-axis="[[xAxisConfig]]" data="[[multiSeriesData]]" plot-options="[[joinedBarsConfig]]" y-label="Value" legend></highcharts-chart>
|| ==================================================*/

//Bind Data
chart.data = [
  {name: 'exponential', data: [1,2,4,8,16]},
  {name: 'incremental', data: [0,1,2,3,4], color: '#ec6464'},
]

//Bind PlotOptions for thin, connected bars
chart.plotOptions = {column: {
  pointPadding: 0,
  borderWidth: 0,
}}

//Make x-axis categorical
chart.xAxis = {categories: ["Jan","Feb","Mar","Apr","May","Jun"]}
