Chapter II-12 — Graphs

II-290

You can also put a cursor on a particular wave using a pop-up menu. Position the mouse over the “A: wave-

Name” or “B: waveName” area of the info box. Then click and choose a wave from the pop-up menu.

Sometimes the graph is not wide enough to see all of the readout area. In this case you can click the left or

right horizontal scroll control to make the readout area scroll horizontally.

If you click the up or down vertical scroll control the entire info box scrolls vertically revealing a list of the

traces and X waves in the graph. Click the vertical scroll again to return to the main info box.

The cursors provide a convenient way to specify a range of points on a wave which is of particular interest.

For example, if you want to do a curve fit to a particular range of points on a wave you can start by putting

cursor A on one end of the range and cursor B on the other. Then you can summon the Curve Fitting dialog

from the Analysis menu. In this dialog on the Data Options tab there is a range control. If you click the “cur-

sors” button in this dialog then the range of the fit will be set to the range from cursor A to cursor B.

Programming With Cursors

These functions and operations are useful for programming with cursors.

The ShowInfo and HideInfo operations show and hide the info panel containing the cursor's homes.

The Cursor operation sets the position of a cursor.

The CsrInfo function returns information about a cursor.

These functions return the current position of a cursor:

These functions return information about the wave to which a cursor is attached, if any:

The CursorStyle keyword marks a user-defined function for inclusion in the Style Function submenu of

the Cursor Info pop-up menu.

The section Cursors — Moving Cursor Calls Function on page IV-299 explains how to trigger a user-

defined function when a cursor is moved.

Identifying a Trace

A help tag or tool tip that identifies a trace and contains information on the waves displayed by a trace can

be displayed when you hover the mouse over a trace. To enable this mode, pull down the Graph menu and

select Show Trace Info Tags.

Subrange Display

In addition to using an entire wave for display in graphs, you can specify a subrange of your data to display.

This feature is mainly intended to allow the display of columns of a matrix as if they were extracted into

individual 1D waves but can also be used to display other subsets or to skip every nth data point. To use

this feature using the New Graph and Append Traces dialogs, you must be in the more complex version of

the dialogs used when you click the More Choices button. You may then add entries to the holding list and

from there you can edit the subrange settings.
