The Parameters tab lets you modify the definition of tree parameters. Specifically, for existing tree parameters you can set new limits and units. You may not set new values for the binning.
The parameters page looks like this:
At any time, exactly one line is active. The line with its radio button checked. Thepulldown menu allows you to load a parameter into that line. The menu is organized to reflect the parameter hierarchy as a menu, sub-menu hierarchy.
If you modify the name field to match an existing parameter, that parameter is loaded as well. You can make as many modifications as you want to the low, high and units fields. If you get hopelessly lost, simply clickto reload the current definition of that parameter. If you click the tree parameter definition will be modified. If you click , any spectra that depend on that parameter will be redefined so that axes depending on that parameter have the new low and high limits.
Thecheckbox affects the and buttons. If it is checked, and the parameter on that line is a member of a tree parameter array, all members of the array are modified on a operation and all spectra depending on all parameters in the array are modified. If is checked, the button modifies all spectra that depend on all paframeters in the tree parameter array that contains that parameter.
