If you do not enter the Flowcharter license key during the installation proces, Flowcharter will run in read-only mode. To add the key it is not necassary to install Flowcharter again.

To display the value-labels of certain graph you will need to do the following:

1. Double-click on the graph. A settings-window should appear
