04 Plots and Cursors

Posted in manual

The plot area contains three elements: an axis, the configured plots and cursors. Cursors are part of a view, like plots and folders, but they are not visible in the view configuration hierarchy. So, if you change the view, you also change to a different set of cursors.

This article is based on impulse 1.8.

Adding, Activating and Deleting Cursors

Initially, one cursor is part of a new view. To add more, press the "Add new Cursor" button in the toolbar or use the context menu of the Axis or Cursor Details. To make a cursor active, you need to press the grip of the cursor in the cursor track of the axis, or you select the cursor in the Cursor Details field. To get rid of a cursor, use the context menu of the cursor (right click on the grip), or the context menu of the axis to delete all cursors.

Switching between cursors

In the context menu of a cursor, you find the commands

Instead of using the context menu, you can click on the cursors in Cursor Details to activate, and double-click to activate and show. It is easier still to use the keyboard shortcuts (see A02 Keyboard Shortcuts).

Moving up/down the signals - expand/collapse folders

To scroll in vertical area, just use the scrollbars, the mouse wheel (without CONTROL keys) or the keyboard (UP, DOWN, PAGE_UP, PAGE_DOWN, POS1, END) as you would do in another editor. Use the SPACE key to expand or collapse folders, or use the tree control.

Moving in time (or frequency,...)

If you move the cursor outside of the plot area, the axis will change to keep the cursors visible. Coloured arrows on both sides show you the speed modes (depending on the mouse’s position relative to the plot area).

Zoom in/out or fit

Move to next/previous event

Select the signals (which may be multiple) that you want to iterate. Press Goto Previous/Next Event in the toolbar or use the keyboard shortcuts (see A02 Keyboard Shortcuts).
