If you are using ScopeView 1.1 or later, follow these steps:
In the background menu of the graphic page, choose the Page Properties… option.
In the Page Properties dialog, select the Legend tab.
Deselect the Visible check box.
Select the Apply To All button.
If you are using ScopeView 1.0, you cannot eliminate the note but there is a workaround if you are creating a JPG file containing only one graph. In the Export dialog, instead of exporting the graph using the From All Pages option use the Selected option.
