Abstract

A system and a machine-implemented method for rendering, on a display device, a first data graph concerning data received from a first data source. A second data graph concerning data received from a second data source is rendered on the display device, and superimposed onto the first data graph to generate a superimposed data graph.

12. The method of claim 10, wherein the data store is a remote data store.

13. The method of claim 10, further comprising:

retrieving one or more of the data graphs from the data store.

14. The method of claim 1, wherein:

the first data source is a baseline data file for a specific data sensor; and

the second data source is an actual data source from the specific data sensor.

15. The method of claim 14, further comprising:

retrieving the baseline data file from a data store.

16. The method of claim 15, wherein the data store is a local data store.

17. The method of claim 15, wherein the data store is a remote data store.

18. A computer program product residing on a computer readable medium having a plurality of instructions stored thereon which, when executed by the processor, cause that processor to:

render, on a display device, a first data graph concerning data received from a first data source;

render, on the display device, a second data graph concerning data received from a second data source; and

superimpose the second data graph onto the first data graph to generate a superimposed data graph.
