Customize Label above Gadget

In this blog, we are going to show a new feature that is introduced in Origin 2022b — Customize Label above ROI box of gadget. We are using quick fit gadget as an example to set custom label of fitting result, . The label text supports rich text and LabTalk expression and notation so once u customize the label, you can choose Output for all layers to get consistent label on all layers as shown in the following multi-panel graph.

Enter the following lines into the entry box and click Apply. Notice the ROI label gets updated.  Notice that rich text (\g(c)\+(2)) and LabTalk Script($(intercept, S.2)) is used here. Check the updated label.
    Fitting Function: y = $(intercept, S.2) + $(slope, .2) * x
    Reduced Chi-Sqr: \g(c)\+(2) = $(chisqr, *4)
    R Square: R\+(2) = $(cod, .4)

  3. To customize the output label:  Go to Label Box tab. The settings under this tab is to customize the label that will be added to the graph as the fitting result.  Make the following changes and make sure to set Parameter Table to Use ROI Box Tab Settings.
