The above window shows the default view for the sample survey. Note that it is a
dual axis graph showing energy in kWh on the LH axis and Volume on the right, and
three data traces are present for electricity, water and gas (1 X bar chart and 2 X line
chart traces). The bar chart is always referenced to the LH Y axis, and the line charts
to the RH one.
Because the chart only has 2 Y axes and the
SPC Pulse is a 3 channel device, the
graph behaviour is dependent on the number of channels used in the survey, and
the unit(s) of measure defined during the download process detailed above. If only
one or two channels are used during the survey, the graph will automatically show
both channels regardless of the programmed units. If all three channels are
populated, the graph will show three data channels provided that no more than two
units of measure are in use. If three different units are present (e.g. kWh, m
3
and ft
3
)
the graph will display channels 1 & 2. The third channel may be manually accessed
via the axis controls as detailed below.
