- Time Series Analysis Demo
-
- The data in this demonstration shows the power,
- measured in megawatts, produced at a large power
- generation station. The data was collected from many
- circuits, every half-hour for a period exceeding one
- year.
-
- Initially, the data is sub-sampled to fit into the
- window and displayed as a 2-D color image where days
- are on the X axis and time of day is the Y axis. The
- color shades represent the data values in megawatts
- with a legend at the bottom of the x window indicating
- the relationship between the color shades and the data
- values.
-
- Drag the cursor over the 2-D color image to get
- specific data readings which are displayed in the lower
- left hand corner of the window. The Time and Date
- Profiles are updated as the cursor moves through the
- image.
-
- You can also view the data as a 3-D surface. You can
- view the data for the entire year, or for any month
- within the year.
