图表

Creates a raster Line, Bar, Scatter, Histogram or Pie chart based on the values of selected attributes. This transformer features an interactive interface that allows the user to preview selected features with sample data while designing the layout of their chart. Multiple data series may be specified for plotting on the same chart and many options for chart presentation and labeling are available. This transformer replaces the deprecated WebCharter transformer.

This transformer allows for the creation of 5 different chart types: Line, Scatter, Pie, Bar and Histogram. Different chart specific options are available for each type.

输入端口

可以从任何一个属性指定图表的输入数据值,或者,或者,列出与webcharter兼容性的属性。

When data is specified from attributes, each specified attribute defines a data series and each feature provides a value in the data series. In this mode, this transformer becomes a blocking transformer, releasing features only after all input features, or all values in the data series, have been received. Thus, the sum of all the input features produce either a single raster chart, or a one per group if通过...分组是enabled.

当通过列表属性指定数据时,每个功能表示一个图表,并且该功能上的每个列表属性都表示图表中的数据序列。在此模式下,该变压器变得不阻止,因为单个要素包含生成图表所需的所有数据,并且为每个输入特征产生一个输出功能。通过...分组settings are ignored in this mode.

Editing Transformer Parameters

使用一组菜单选项,变压器参数s can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click除适用的参数旁边。有关更多信息,请参阅变压器Parameter Menu Options
