Hi joeycao,
To get a general idea of which sequence of commands you'll need to use to create these charts and configure them as you like, your best bet is to record a macro in Excel, doing the steps, and then later examine which are used. You'll then be able to use invoke nodes to make these ActiveX calls in the proper sequence.
Please refer to this knowledgebase,
Using National Instruments Software to Control Microsoft Excel with ActiveX for a description of how to do this.
Hopefully that gets you started on the right path.
