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.
