This view is used in many places to display graphical information. The view may be a simple graph for a single parameter or multi graph reports comparing observed against model data.
Context menu
The graph context menu provides options that are dependent on the graph type.
Export traces to CSV
Select this option to export traces from the Graph View to CSV format allowing graph data to be viewed in other applications. See Exporting Traces to CSV for further information.
Create scatter graph
Select this option to generate a scatter graph from the existing graph. A scatter graph is a statistical diagram drawn to compare two sets of data. It can be used to look for a correlation between the two sets of data. See Generate Scatter Graph dialog for further information.
Graph properties
For most graphs, many changes are made on the Graph Properties dialog, which can be launched by right clicking on the Graph View and choosing Graph Properties from the popup menu. The changes you can make on this dialog are:
- Overall graph title and appearance, including display of grid lines.
- Changes to the graph axes. Titles, font, size and colour can all be changed. The minimum and maximum scales can be set by you or calculated automatically. All changes can be made independently for each axis.
- Change the way each trace is drawn, including colour, line thickness and optional symbol. Different styles can be used for screen and print.
Other graph properties
Other aspects of the graph are described below.
Zooming
To zoom in on part of the graph, click
on the toolbar, or hold the Shift key and drag the mouse across the area you wish to magnify. This creates a rubber band box that extends horizontally across the zoom area. The mouse must start within the boundary of the graph itself.
To zoom out, click
on the toolbar and then click within the graph area to zoom out to the previous zoom extent.
To restore the original time axis, double-click within the graph area with the left mouse button.
Tooltips
Hover over the trace or data point with the cursor to display a tooltip showing the graph value.
Values at locations on traces between data points will be interpolated. An interpolated value is denoted in the tooltip by an asterisk after the trace value.
Copying and printing
The graph can be copied to the clipboard or saved to a file in Windows MetaFile (WMF) format. It can also be printed.
- To copy the graph as a Windows MetaFile, choose Copy/save view / Clipboard (WMF) or Copy/save view / File (WMF) from the Edit menu.
- To print the graph, choose Print from the File menu. You can also:
- Preview the print by choosing Print preview from the File menu.
- Setup the margins for the page by choosing Page setup from the File menu. This displays the Graph Page Setup dialog.
