如何为kendo-chart-category-axis-item-labels设置文本值

Question

我想在图表的开头显示图表类别的轴标签，因为我正在使用AxisLabelsPosition。它在开始时显示，但在x轴上也显示。

我不想在x轴上显示。有什么方法可以实现这一目标。

Answer 1

应该可以避免使用第二个轴重复标题：

<kendo-chart-category-axis>
    <kendo-chart-category-axis-item >
        <kendo-chart-category-axis-item-labels rotation="auto" [position]="categoryLabelsPosition">
        </kendo-chart-category-axis-item-labels>
    </kendo-chart-category-axis-item>
    <kendo-chart-category-axis-item [title]="{text:'testing'}" [line]="{ visible: false }" name="titleAxis">
    </kendo-chart-category-axis-item>
</kendo-chart-category-axis>

<kendo-chart-value-axis>
    <kendo-chart-value-axis-item  [axisCrossingValue]="[0, -1000]">
        <kendo-chart-value-axis-item-labels [position]="valueLabelsPosition">
        </kendo-chart-value-axis-item-labels>
    </kendo-chart-value-axis-item>
</kendo-chart-value-axis>

我也将其报告为错误。这两个地方显示的标题对我来说似乎不合适。

Answer 2

标题是一行文本。 只需编辑以下行即可设置表格标题：

  <kendo-chart>
    <kendo-chart-title text="Title" position="bottom"></kendo-chart-title>
  </kendo-chart>

通过设置position，您可以决定文本的显示位置。

对每个图表项目重复标签。 删除/设置每个数据项的标签（axis-item-labels）：

  <kendo-chart>
    <kendo-chart-series>
      <kendo-chart-series-item type="column" [data]="data" field="TMax">
      </kendo-chart-series-item>
    </kendo-chart-series>
  </kendo-chart>

解决方案由剑道团队提供。

我将其作为错误提出，并已在kendo-angular-charts v 3.3.2中修复
