Auxiliary Graph
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.
