There are many ways to save your charts in MotiveWave. If you close MotiveWave from the Console window (look for the chart or window that says MotiveWave Console at the top), it will automatically ask you if you want to Save all of your open charts. You can also use the Save or Save As icons in the top toolbar, or go to File > Save All or File > Chart and choose Save or Save As. There is also an Auto Save feature that you can enable that will automatically save your charts based on how often you want them saved (once every 5 mins, once a day, etc.). You can find the Auto Save under Configure > Preferences. In the General tab, check the box for Auto Save Enabled and specify the Auto Save Interval in seconds.
