是否可以在图表中添加标题? [英] Is it possible to add title to charts?

问题描述

我想为图表添加标题，例如 仪表示例或饼图.我想在图表下方或上方显示标题.这可能吗?我一直在寻找，但找不到任何关于此的信息.如果是这样，有什么建议可以分享吗?它会是这样的

I want to add a title to a chart, like in the gauge example or a pie chart. I want to display a title under or on top of the chart. Is this possible? I've been looking and can't find anything about this. if so , any tip to share? it would be something like this

编辑:我发现有一个属性可以为 Ex.draw 上的标题或任何标签创建 text sprites包.但我无法理解如何使用它..

EDIT: i found there is a property to create text sprites for the title or any labels at the Ex.draw package. but i couldnt understand how to use it..

这里有人做过吗?

推荐答案

由于 Ext.chart.Chart 是一个 Ext.draw.Component，您可以添加精灵作为它的项目.尝试使用这个:

Since Ext.chart.Chart is an Ext.draw.Component, you can add sprites as items of it. Try to use this:

Ext.create('Ext.chart.Chart', {
   default chart settings here

   ...

   items: [{
      type  : 'text',
      text  : 'Simple Title',
      font  : '14px Arial',
      width : 100,
      height: 30,
      x : 50, //the sprite x position
      y : 10  //the sprite y position
   }]
})
