Changing the legends for functions
The Legend page controls whether a legend appears on the contour VOI graph or intensity graph and allows you to assign a specific name to each function. By default, the legend does not appear on the graph; however, when you choose so, the legend appears in the upper right corner of the graph.
To display or hide legends
1 Open an image.
2 Delineate a VOI on the image.
3 Generate an intensity profile (refer to [MIPAV_Analysis.html#1082499 "Generating graphs" on page 325]). Either the Contour VOI Graph window ([MIPAV_Analysis.html#1039942 Figure 204 on page 325]) or the Intensity Graph window ([MIPAV_Analysis.html#1038580 Figure 205 on page 329]) opens.
4 Select Views > Modify Graph Features in either the Contour VOI Graph window or the Intensity Graph window. The Modify Graph dialog box ([MIPAV_Analysis.html#1361809 Figure 207 on page 332]) appears.
5 Select the Legend tab. The Legend page ([MIPAV_Analysis.html#1040215 Figure 215]) appears.
6 Do one of the following:
To display the legend on the graph, select Show legend. A check mark appears in the check box.
To hide the legend, clear Show legend. The check mark disappears from the check box.
7 Click Apply.
If you selected Show legend, the legend appears in the upper right of the graph ([MIPAV_Analysis.html#1046267 Figure 216]).
If you cleared Show legend, the legend disappears from the graph.
8 Do one of the following:
Close the Modify Graph dialog box.
Keep the Modify Graph dialog box open to continue modifying the graph.

To display the points, select Points visible. A check mark appears in the check box.
To make the points invisible, clear Points visible. The check mark disappears from the check box.
6 Click Apply.
If you selected Points visible, the points appear on the functions ([MIPAV_Analysis.html#1046499 Figure 218]).
If you cleared Points visible, the points disappear from the function.
7 Do one of the following:
Close the Modify Graph dialog box.

Modifying functions on graphs
The graph modifying or fitting is designed for fitting of statistical functions used in parameters' evaluation. Available functions are currently various statistical functions with linear or exponential autocorrelation functions. In the Fitted Functions tab, you can select the autocorrelation function and then fit the data.
As the result you will obtain the fitted curve and the set of its parameters. The fit report will appear in the Fitting Data tab and can be saved into a file using Save Messages button.
