I want to use the tool "regional data range" to select a range of data in Layer 2 of a graph, and have a script that uses that range selected to define the fitting range for data plotted in Layer 1.
How can I access the upper and lower x range selected by the regional data range selection tool? I can't find this in the manual.
Thanks! |

Assuming you have only one dataset in layer 1 or the dataset you are interested in is the active dataset, and that the two layers share the same X dataset, here is one way. Run this script after setting the markers in layer 2:
mrk1=mks1; // This remembers the lower bound market 'mks1'
mrk2=mks2; // This remembers the upper bound market 'mks2'
page.active = 1;
set %C -b mrk1;
set %C -e mrk2;
After you are done fitting in layer 1 you can use the Data menu "Reset to Full Range" or execute:
set %C -b;
set %C -e;
If the X are not shared, then you must convert these indexes to X values and find corresponding X values in the other dataset. xindex finds the X equal to or less than and xindex1 finds the X equal to or greater than.
px1=xof(%C)[mks1];
px2=xof(%C)[mks2];
page.active = 2;
newx1=xindex(px1,%C);
newx2=xindex1(px2,%C);
set %C -b newx1;
set %C -e newx2;
