所有图表类型(除了饼图)都可以拥有多个系列。
Listing 4 shows a modified version of the pie that allows the user to pick which series of data is shown.
清单4显示了扇形图的修改版本,此版本允许用户选择将要显示的那个系列的数据。
Now you can switch data series and even apply aggregation to transform the data before it is used to create the pie chart.
现在,在数据用于创建扇形图以前,您可以切换数据系列,甚至应用汇集来转换数据。
In a pie chart, only a single data set (the first data point in each series) is represented on the chart.
在饼图中,只在图表上表示单个数据集(每个数列中的第一个数据点)。
