The increase (INC) and decrease (DEC) plots are types of sequential plots. An increasing plot only
displays points when the X-axis values are increasing. A decreasing plot only displays points when
the X-axis values are decreasing. The increasing and decreasing sequential plots are especially
useful if you are profiling and display depth on the X-axis. Thus the plot shows only the time in
which the sonde is being lowered or raised.
Select Cross-parameter bins to set up the number of bins that will appear on the X-axis. This
feature only applies to reports and averaged plots (see descriptions above) with a parameter other
than Date + Time on the X-axis. Changing this value modifies the number of bins into which the
X-axis is divided. The smaller the number of bins, the wider and more general is the plotted
information. The maximum number of allowable bins varies with the capability of your computer
system, and is displayed in parentheses. For example, 100 is selected, and the maximum is 2350 as
shown in the screen above.
Select Parameters per plot option to setup the number of parameters that will be plotted together.
If you choose 1, there will be an individual X and Y-axis displayed for each selected parameter.
Select any number of parameters per plot, (from 1 to 4) which provides your data with the best plot
presentation.
Select Scaling Info from the Modify menu.

There are three scaling options.
Default Scaling offers fixed limits. These limits correspond to the range of each parameter
as defined by the sensor specifications, so your plot will always fit within these limits.
Manual Scaling allows you to enter custom limits for each parameter.
The computer scans the data file and determines the limits, then displays those limits on the
plot in Automatic scaling.
NOTE: When entering a scaling technique, you need only type the first letter of the desired
technique and press Enter. PC6000 will fill in the rest.
Select Copy default to manual or Copy automatic to manual to provide a quick way to copy
from either the default or automatic limits columns to the Manual scaling column.
