Shift a vector
1. vshift ix:=col(1) delta:=3 fill:=0 ox:=col(1);
2. vshift ix:=col(1) delta:=3 fill:=0 ox:=<new>;
Please refer to the page for additional option switches when accessing the x-function from script

Default Value |
Description |
|---|---|---|---|---|
| Input | ix |
Input vector |
|
Specifies the input data to be shifted. |
| Shifted Position (First Row) | delta |
Input int |
|
Specifies the new position for the first row. |
| Padding | fill |
Input double |
|
Specifies a padding value. Cells in the output vector whose indices are less than the delta variable will be filled with this value. |
| Output | ox |
Output vector |
|
Specifies the output for the shifted vector. |
The vshift function shifts the input vector and pads the first few cells in the new vector with a specified value.
// The vshift function can be used in situations where two datasets // share an X column, but you wish to move one dataset relative to; // another in the X direction. This amounts to moving the data in the; // worksheet down (vertically, thus 'v'shift) // New book and import data newbook; path$ = system.path.program$ + "Samples\Curve Fitting\Enzyme.dat"; impasc fname:=path$; // Plotting columns 2 vs 1 and 3 vs 1 range r1 = (1,2); range r2 = (1,3); win -t plot line; plotxy r1 plot:=200 color:=color(orange) ogl:=1; plotxy r2 plot:=200 color:=color(olive) ogl:=1; win -z; //Maximize window // Pause so we can see the shift between our two curves type -b We will use the vshift function to shift the first curve to match the second in the region above 10uM.; // Now shift by 3 rows by padding with missing value and replacing the original data range -w rWks = 1; // -w switch gets a worksheet range of plot object vshift ix:=rWks delta:=3 fill:=0/0 ox:=<input>;
