The Compare VIs tool, also called Graphical Differencing, helps you track changes in your application by comparing multiple versions of a VI. This becomes especially important as your project grows and involves more developers.
Use the Tools»Compare»Compare VIs tool to display the Compare VIs dialog box. You can select options to control the types of differences you want to detect and view. For example, you can filter out cosmetic changes such as objects being moved or resized. When you compare the VIs, a dialog displays a summary of the differences. If you select an item from the summary, Compare VIs displays and highlights the differences between the two VIs.
Complete the following steps to compare two VIs.
Comparing very large VIs can be lengthy. You can cancel the comparison of two VIs in the Comparison Progress dialog box.
The progress bar indicates the steps in the comparison algorithm, not the number of differences left to find. When the comparison is complete, the front panels and block diagrams of the two VIs are displayed along with the Differences dialog box.
