Plotter Controls

Plotter controls are shown slightly magnified in the upper left of the capture above. From the left, they
control:

RESUME TRACKING - causes the strip-chart to resume automatically tracking
changes in voltage, time, or temperature

in other words, resume auto-ranging. This

green arrow is illuminated after manually zooming in or opening a window in the
default view. The default is auto-ranging is enabled. The small black down-arrow
opens a small menu of selections controlling the automatic tracking. Whether
displayed or not, data is always captured on each poll refresh.

PAUSE DISPLAY

momentarily stops auto-tracking. To resume, use the RESUME

TRACKING button described above.

SCROLL X-Y

After clicking this control, the display (data) window can be moved by

left-clicking the mouse button in the display and moving the mouse. Use RESUME
TRACKING to restore the display. Each data set (VCn voltages, VBRICK, temperature,
time) scale can be individually moved by clicking and holding the left mouse button on
the units field and scrolling up-down or left-right (time scale).

EXPAND X-Y

This control allows zooming in or out on the displayed scale. Choose

this button, then click and hold the left mouse button to operate. Each data set (VCn
voltages, VBRICK, temperature, time) scale can be individually zoomed by clicking and
holding the left mouse button on the units field and scrolling up-down or left-right (time
scale).

ZOOM OUT

click on a scale, then click this button to move out in incremental steps.

ZOOM IN

similar but opposite action to Zoom out, above.

SELECT

allows selecting data or scales (opposite of window mode, described next)

WINDOW

click this button, then drag a zoom box around an area in the display to

zoom in. This mode is canceled by clicking on the SELECT arrow described above.
The display is restored by using the TRACKING RESUME button, above.

COPY TO CLIPBOARD

the data is copied to the clipboard for inclusion in a

document or spreadsheet. A small menu allows selecting the numeric data to copy, or
the graphic.
