16Create <b>Batch Page </b> by selecting <b>Batch </b> radio button on
17Data Explorer<font color="blue"><a href="#batch_button">(see figure below)</a></font>

22<br />
23Load Data to Data Explorer if not loaded. <br/>
24Select one or more data sets by checking the check boxes, and then make sure
25that "Fitting" is selected in the dropdown menu next to the "Send To" button.
26Once ready, click the 'Send To' button to set data to a BatchPage. If already an empty batch page exists, it will be set there.
27Otherwise it will create a new Batch Page.
28Set up the model and the parameter values as same as a single fitting <font color="blue"><a href="single_fit_help.html">(see single fit help)</a></font>.
29The use 'Fit' button to perform the fitting.
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.

40Batch Window provides an easy way to view the fit results, i.e., plot data, fits, and residuals.
41Batch window will be automatically shown after a batch fit is finished. <br />
42Once closed,
43it can be opened anytime from the "View" menubar item <font color="blue"><a href="#figure2">(see Figure 2)</a></font>.<br />

60Once a batch fit is completed, all fitted and fixed model parameters are displayed to the current sheet of
61the batch window except the errors of the parameters. To view the errors,
62click on a given column then under <b> Edit </b> menubar item, and insert the desired parameter by selecting
63a menu item with the appropriated label. Empty column can be inserted in the same way.
64A column value can be customized by editing an existing empty column.<br />
65To Remove column from the grid, select it, choose edit menu, and click the <b> 'remove' </b>  menu item.
66Any removed column should reinserted whenever needed.<br />
67All above options are also available when right clicking on a given column label
68<font color="blue"><a href="#figure3">(see Figure 3)</a></font>.
69<b>Note:</b> A column always needs to be selected in order to remove or insert a column in the grid.<br /><br />

80menu item to save it as a .csv file. <br />
81<b>Note: </b> The grid doesn't save the data array, fits, and the array residuals. As a result, the 'View (fit) Results' functionality
82will be lost  when reloading the saved file.<br />

93All columns in the file will be displayed but insertion will not available.
94Insertion will be available only when at least one column will be

104To <b> plot </b> a column versus another,
105select one column at the time, click the <b> 'Add' </b> button next to the text control
106 of X/Y -axis <b> Selection Range </b>
107to plot the value of this column on the X/Y axis. Alternatively, all available range can be selected by clicking the column letter (eg. B).
108Repeat the same procedure the next axis. Finally, click the <b> 'Plot' </b> button.
109When clicking on <b> Add </b> button, the grid
110will automatically fill the axis label, but  different labels and units can be
111entered  in the correct controls before clicking
112on the plot button.<br />
113<b>X/Y -Axis Selection Range </b> can be edited manually. These text controls
114allows the following types of expression:<br />

1201) if the current axis label range is a function of 1 or more columns,
121 write this type of expression: <br />

130
1312) if only some values of a given column are need but the range between
132the first row and the last row used is not continuous,<br />write
133the following expression in the text control: <br />
134<font color="#CC9933">column_name1</font>

144<b>Note: </b>Both text controls ( X and Y-axis Selection Ranges) need to be filled
