Modifying graphs

You can zoom into a graph by holding down the ALT key and dragging a box around the area that you want the graph to display. When you release the mouse button the region selected will be expanded to fill the graph. Mouse shortcuts can also be used: CTRL+wheel to zoom, SHIFT+drag to pan. If you want to reverse this process then right click the mouse and choose use default ranges from the popup menu.

You can also change the appearance of a graph by double clicking on the graph or by selecting properties from the graph's popup menu. the graph properties dialog then allows you to change the following aspects of the graph.

Axes

You can set the range, the tick spacing and the number of small ticks. The use default tick spacing button sets the tick spacing and the number of small ticks to sensible default values based on the range. This is useful if you want to set the range to a specific value and want the tick spacing to be set automatically.

Labels

You can alter the text and fonts of the axis and tick labels.

Curves

You can control the line properties and visibility for each curve on the graph.

Legend

The legend is a key showing which curve is which. It only appears on graphs that have multiple curves, e.g. range graphs. You can control whether the legend is shown and if so where and using what font. Note that the legend includes all the curves, even if some of them may not be visible at the time.

Set as default

Changes to a graph's properties normally only apply to that graph. But for general settings (fonts etc.) you can also click the set as default button. OrcaFlex then remembers the current settings for use with future graphs.
