在折线图中，x轴表示不同的类别，但在散图中，它表示变量的实际值。
散点图有两个值轴:水平(x)和垂直(y)值轴。它将x和y值合并为单个数据点，并以不规则的间隔或集群显示它们。散图通常用于显示和比较数值，例如科学、统计和工程数据。
散点图类型:
散点图:这类图表显示了基于选定数据范围的点，这些点可以发现变量X和y之间是否有关系。
带平滑线和数据标记的散点图:与基础散点图相比，这类图表显示了数据连接点的平滑曲线。
带平滑线的散点图: 与基础散点图相比，这类图表显示了一条平滑的曲线，连接了数据点并删除了所有的点。
带直线和数据标记的散点图:与基础散点图相比，这类图表显示了数据连接点的直线。
带直线的散点图: 与基础散点图相比，这类图表显示了一条直线，连接了数据点并删除了所有的点。
气泡图:这是一个特殊的散点图。
气泡图是散点图的一个变化版本，在这个图中，数据点被气泡取代，而数据的另一个维度以气泡的大小表示。就像散点图一样，气泡图不使用范围轴——水平轴和垂直轴都是值轴。此外，x值和y值是在散点图上绘制的，一个气泡图包含了x值、y值和z(大小)值。
如果数据包含三个数据序列，每个都包含一组值，那么您可以使用一个气泡图表而不是散点图。气泡的大小是由第三个数据系列中的值决定的。气泡图经常被用来展示金融数据。不同的气泡大小对于视觉上冲击是很有用的。
