Enable Temporary File(s) Creation 
In the upper left corner of the user interface, click the (Options) icon.
By default, the Enable Temporary File(s) Creation is enabled. When enabled, temporary files are created during battery operations. With the existence of the temporary files, user experience on the zoom in and out features of the chart will be improved.
Click again to disable this function.
This option is not available if data is displayed on the chart for both Battery Emulator and Battery Viewer tab. In this case, disconnect the instrument or close this application, then reconnect the instrument or relaunch the application.
