01、QDateTimeAxis
QDateTimeAxis 是 Qt 中用于图表的轴类，它专门用于处理日期和时间数据。这个类允许你在图表上显示和解释与日期和时间相关的数据点。例如，在 Qt 的图表库中，你可以使用 QDateTimeAxis 来创建一个时间序列图表，展示股票价格、天气数据或其他随时间变化的数据。
02、QValueAxis
QValueAxis 是 Qt 中用于图表的另一个轴类，它用于表示数值数据。这个类允许你在图表上显示和解释数值数据点。QValueAxis 可以用于各种类型的图表，如柱状图、折线图和散点图等，以展示不同类别的数据值。
03、QChartView
QChartView 是 Qt 中的一个类，用于展示 QChart 对象。QChart 是一个高级图表组件，它可以包含多种类型的图表，如折线图、柱状图、饼图等，并且支持多种数据系列和数据点。QChartView 提供了一个视图，使得 QChart 可以被嵌入到图形用户界面（GUI）中，以便用户可以交互式地查看和分析数据。

08、QPieSeries
QPieSeries 是 Qt 中 QChart 类的一个成员，用于创建饼图系列。饼图是一种常见的图表类型，用于展示各部分占整体的比例关系。QPieSeries 可以包含多个数据点，每个数据点对应饼图中的一个扇区。
09、QPieSlice
QPieSlice 是 QPieSeries 类的一个内部类，它代表饼图中的一个扇区。每个 QPieSlice 都有一个对应的值和角度，这些属性决定了它在饼图中所占的比例和位置。你可以通过设置 QPieSlice 的值来改变扇区的大小，从而反映不同数据点在总体中的比例。此外，你还可以设置扇区的颜色、标签等属性，以增强图表的可读性和美观性。
