     30<br />Unlike a single fit, the results of the fittings will not return to the BatchPage'. Instead, a Grid window will be provided once the fitting is completed.  
     31The Grid window is also accessible from the 'View' menu <font color="blue"><a href="#figure2">(see Figure 2)</a></font>.  
     32<br /> Note that only one model is used for all the data.  
     33The initial parameter values given in the control page will be used all the data fittings. If one wants the FitEngine to use the initial values  
     34from the results of the previous data fitting (if any), choose the 'Chain Fitting' in the Fitting menubar, which will speed up the fitting  
     35especially when you have lots of, and similar, data sets.
