我在R中执行一些分析并生成两个XML文件。第一个输出文件采用FusionChart Free Chart的格式:
<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">

我的问题是在查看完整图表后,用户只希望在不同时间间看到数据。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。可以使用PHP表单(或类似的东西)来完成吗?
答案 0 :(得分:0)
是的,这很有可能使用PHP。如果您希望编辑您所显示的XML并按照所选时间范围保留一些元素,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
生成特定于FusionCharts的XML
或
使用表单元素选择时间范围。
解析创建的FusionCharts特定XML,以删除不属于范围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。
