你好,我想问一下用NCL 怎么讲ISCCP可视化啊,虽然有NCL的例子,但是在处理的时候出现了问题,fatal:MeshScalarFieldInitialize: Insufficient number of elements in sfDataArray fatal:Unable to initialize layer-Can't Create fatal:Unable to access object with id:-4 fatal:Unable to access object with id:-4 warning:Unable to add DataItem "(null)" to DataList "cnScalarFieldData" fatal:CompileDataList:DataList has no valid members fatal:NhlGetValues:PID #-4 is invalid 要问一下怎么解决啊 ... ...
