使用FusionCharts Free for axis在图形中向下钻取

我有以下输入xml文件：

我在R中进行了一些分析，并生成了两个XML文件。第一个输出文件的格式为FusionChart自由图表：

<graph caption="Share Data Wave" subcaption="For Person's Name" xAxisName="Time"  yAxisMinValue="-0.025" yAxisName="Voltage" decimalPrecision="5" formatNumberScale="0" numberPrefix="" showNames="1" showValues="0" showAlternateHGridColor="1" AlternateHGridColor="ff5904" divLineColor="ff5904" divLineAlpha="20" alternateHGridAlpha="5">

我的问题是，在看到完整的图表后，用户只希望看到不同时间段的数据。在上面的格式中，它将是名称标签。如何编辑xml文件以仅显示请求的数据点。这可以使用PHP表单（或类似的东西）来完成吗？

是的，这很可能是使用PHP实现的。如果您希望按所示编辑XML，并根据选定的时间范围保留某些元素，请按照以下步骤操作：

步骤可以是：

使用表单元素选择时间范围

根据范围，使用PHP XML解析器选择属于该范围的数据

生成FusionCharts特定的XML

或

使用表单元素选择时间范围

解析创建的FusionCharts特定XML，以删除不在范围内的集合节点的名称属性的所有值

使用此最终XML生成图表

我可以在这里为您提供一个小的PHP示例，以便您可以使用它
