散点图

散点图广泛用于说明各个项目或类别之间的关系。 该图表非常适合显示科学，统计和工程数据的比较。

可以在散点图中绘制表单的列或行中排列的数据。 与其他图表不同，散点图在绘图区域中分别在水平轴（也称为X轴）和垂直轴（也称为Y轴）中显示x和y变量的实际值。 通常，此图表将x和y值组合为单个数据点，并以不规则的间隔显示它们。 另外，该图表不使用类别轴，因为水平轴（主轴）和垂直轴（第二轴）都是值轴。

SpreadJS支持以下类型的散点图。 在下面显示的示例中，借助不同类型的散点图描绘了许多男性和女性的身高和体重分布。

• 散点图 簇状散点图基于选定的数据范围显示数据点。 这可以帮助用户分析和确定x和y变量之间的关系。 An image of a scatter chart is shown below:
• 带平滑线和数据标记的散点图: 带有平滑线和标记的散点图显示一条平滑曲线，该曲线连接特定系列中的所有数据点。 带有平滑线和标记的散点图的图像如下所示：
• **带平滑线的散点图: ** 带有平滑线的散点图显示一条平滑曲线，该曲线连接特定系列中的所有数据点，而不显示各个点。 带有平滑线的散点图的图像如下所示：
• 带直线和数据标记的散点图 带有直线和标记的散点图显示一条直线，该直线连接特定系列中的所有数据点。 下图显示了具有直线和标记的散点图：
• **带直线的散点图: ** 带直线的散点图显示特定系列中数据点之间的直线连接线，而不显示各个点。 带有直线的散点图的图像如下所示：
• 气泡图 气泡图非常适合财务数据分析。 它显示了散点图的变体，其中数据点被气泡替换，气泡尺寸代表三维（Z轴）。 该图表绘制了z（size）值以及x值和y值。 通常，当您要绘制三个数据系列时，可以使用此图表。 气泡的大小由第三数据序列中的值确定。 气泡图的图像如下所示：
