To change the offset setting of an axis, simply grab the axis and drag it to the required position, see animation 1 for an example.

To change the gain setting, grab one of the end bars of an axis and drag it to the preferred position, see animation 2 for an example.

It is also possible to adjust the offset and gain with the mouse wheel: when the mouse pointer is above the axis and the wheel is turned, the offset is adjusted. When the CTRL-key is pressed during the turning of the wheel, the gain is adjusted instead.

Double-clicking the axis will return it to its default unzoomed state.

The width of the scroll bar represents the total record, the width of the slider represents the visible part of the record. To change the record view offset, grab the slider and drag it to the preferred position (animation 3) or press the buttons at the sides of the scroll bar. To change the record view gain, drag one of the edges of the slider either to the left or the right and watch the signal change corresponding to the slider width (animation 4).

It is also possible to adjust the offset and gain with the mouse wheel: when the mouse pointer is above the scroll bar and the wheel is turned, the offset is adjusted. When the CTRL-key is pressed during the turning of the wheel, the gain is adjusted instead.

Double-clicking the slider or pressing the hotkey T will return the time base to its default unzoomed state.

If you want to view a small section of your measurement simply drag a rectangle at the section you want to see in detail, see animation 5. Multiple zoom operations are remembered and it is possible to unzoom with hotkey U.

Creating multiple graph's can easily be done by right-clicking on the graph area, and select make new graph. Then drag a rectangle at the position you like to have a new graph. The rectangle may be dragged over multiple existing graphs.

In each graph, cursors can be used to measure values of interest between the cursors. Measurements include: Mininum, Maximum, Top-Bottom, RMS, Mean, Variance, Standard deviation, Frequency.

The cursors can be enabled by:

• using the "Show cursors" button () on the toolbar
• clicking "Show cursors" in the graphs' popup menu.

For clarity, not all measurements are enabled by default when the cursors are enabled. The cursor window will by default look like in the figure below.

Except for the "Left" and "Right" values, all measurements are calculated over the data in between the two cursors. Besides the calculated values in between the cursors, the positions of the cursors, as well as the difference between them, can be seen at the bottom of the cursor window.

The measured values can be copied to the clipboard as text, by pressing the button.

Enabling or disabling measurements can be done by clicking "Select measurements..." in the popup menu of the cursor window, or by clicking the button on the toolbar. A window as depicted below will popup, in which the desired measurements can be selected.

Note: For the frequency measurement, at least one cycle must be in between the cursors. Furthermore, at least two rising slopes must be present in the signal.

Sometimes it is clarifying to add a text comment to a graph, to explain certain phenomena in the measured signals. An unlimited amount of comments can be added to each graph and an unlimited amount of arrows can be drawn from each comment to point at the signals.

A comment can be added by:

• using the "Add comment" button () on the toolbar
• clicking "Add comment" in the graphs' popup menu.

The comments can be dragged to the desired position. Arrows can be created by "dragging" from the little square at the middle of the bottom of the comment to the desired position. You can move an existing arrow by dragging its point to a new position. To delete an arrow, right-click on its point and click 'delete'.

Note: Text is stored in a language dependent field in setfiles. Therefore, comments should be entered in the language of the user interface. This will make easy translation of setfiles possible.
