Values 2
The 'Values 2' page in the Tools tab-pages contains commands that operate on the Values in the rows of the current CPT File. The commands are:
1/ Apply Values in 'Range' and 'Hinge' to Normalized Table-Values
This command will convert 'Normalized' values to metre or feet values. It requires that the CPT file Values have already been 'Normalized' - in other words, that all the Values are in the ranges: [-1,0] or [0,1] or [-1,1]. In addition, it requires that the 'Range' value, located at the bottom of the current CPT file in the CPT File Window has a valid metre or feet value. If that Range value crosses zero, then a 'Hinge' value is also used, though if one is not present, a Hinge of '0' will be assumed. You can change the Hinge value to any value present in a cell in the 'From: Value' column by using the command on the 'Tools > Config' tool-page.
This command acts on the entire CPT file, so there is no need to select start or finish rows.
2/ Normalize the Table-Values by converting Metre Values to [0,1]
This command will convert 'Denormalized' values (i.e. values that are outside the range: [-1,1]) to the ranges: [-1,0] or [0,1] or [-1,1]. It requires that the CPT file Values are currently in metres or feet.
If the current range of values crosses zero (i.e. -8000/8000), then a Hinge Point will be needed. The Hinge Point is shown for each CPT File in the box adjacent to 'Hinge:' on the CPT File Window. If the Hinge Point is absent, it is assumed to be zero, but you can change it's value to any value present in a cell in the 'From: Value' column by using the command on the 'Tools > Config' tool-page.
3/ Create Gradient between Row aa & bb using Values xxxx to yyyy
This command will create a gradient in the 'From Value' and 'To Value' columns. Choose the starting row for your gradient with the 'Row aa' control, and the ending row for your gradient with the 'Row bb' control. The values for the start and end of your gradient are obtained from the 'Value xxxx:' and 'Value yyyy:' boxes. The gradient can be either linear or logarithmic, as selected in the 'Gradient-Type' panel.
4/ Create Gradient between Row aa & bb using aa & bb Row Values
This command will create a gradient in the 'From Value' and 'To Value' columns. Choose the starting row for your gradient with the 'Row aa' control, and the ending row for your gradient with the 'Row bb' control. The value for the start of your gradient is obtained from the 'From Value' of your starting row. The value for the end of your gradient is obtained from the 'To Value' of your ending row. The gradient can be either linear or logarithmic, as selected in the 'Gradient-Type' panel.
