Preview Graph
Displays/hides an auxiliary graph. The auxiliary graph is designated for displaying the cut-out performed in the main graph. The command can also be found in the local menu invoked by right clicking above the area of the graph. The auxiliary graph is always displayed in its original size.
Caution:
If the size of the graph pane part falls below certain dimensions, the auxiliary graph is no longer displayed, regardless of the activatedPreview Graph command. In such a case the graph can again be displayed by shifting the splitter separating the graph from the tables or by enlarging the entire Chromatogram window.
Note:
The original size means either the size where the chromatogram fills the entire graph or a fixed size preset by the Range - Fixed commands from the Graph Properties - Signal Axis and Graph Properties - Time Axis dialog.
