Edit mapping parameters
When Show Advanced Tools is selected in the Advanced preferences pane, you can set the
maximum and minimum range values and invert the range for the selected parameter mapping
in the Parameter Mapping area of the Smart Control inspector. Each mapping can have its own
values, including multiple mappings for the same screen control.
You can also scale input values using the parameter mapping graphs.
Edit mapping parameters for the selected screen control
Do any of the following:
m To set the maximum (high) value for the mapped parameter: Drag the Range Max value slider.
m To set the minimum (low) value for the mapped parameter: Drag the Range Min value slider.
m To invert all values between the maximum and minimum value: Select the Invert Range checkbox.
Scale values using parameter mapping graphs
Each parameter mapping has a Parameter graph. When Show Advanced Tools is selected in
the Advanced preferences pane, you can edit the graph to remap (or scale) input values from the
screen control to different output values. The graph includes a series of preset curves that you
can apply. The graph for one mapped parameter can be copied and pasted to another mapped
parameter. You can also invert the range of values, or reset the graph.
Open the Parameter graph
m In the Parameter Mapping area of the Smart Control inspector, click the Scaling: Open button.
The Parameter graph window opens. The title of the graph window shows the parameter name.
The graph shows the range of input values on the horizontal (x) axis, moving from left to right,
and the range of output values on the vertical (y) axis, moving from bottom to top.
In the graph window, you have several ways of working: you can edit the graph curve directly,
set the graph to use one of the predefined curves, or change the minimum and maximum range
values for the graph.
