To optimize the Graphics window, open the Options configuration dialog from the
popup menu or the window's toolbar. After pressing the [Measurement] button you
will be presented with the measurement options, where you can optimize the following
Parameters of the Graphics window:
Buffer size
Here you set the time interval that is to be saved (in seconds) for the signal responses
of all signals configured in the Graphics window. For example, if you
enter the value 10 here, the last 10 seconds of your measurement in the Graphics
window are always saved and will be available to you after the end of measurement
for further evaluation. Consequently, high values for this parameter will
- particularly when displaying many signals - result in a large memory requirement,
but will allow you to track and evaluate the signal response over a correspondingly
large time period after the end of measurement.
After the measurement stop, with large signal buffers some functions may become
lethargic, such as moving or fitting signals, since in this case large quantities
of data must be redrawn. Therefore, you should select a value for the buffer
size that is as small as possible.
Buffer limit
In addition to buffer size, you can also specify a buffer limit in kB. This defines
the maximum memory usage by the Graphics window during the measurement.
Above all, this is advisable if you have specified a relatively large time span as
the buffer size. Without this maximum limit, more and more memory is demanded
by the operating system over the course of the measurement. This can
lead to severe loading of the overall system due to swapping out of storage.
Please refer to online Help for further details.
User-defined refresh
Scrolling
Here you define how often the Graphics window display should be updated.
Small values result in continuous display of the signal response, but on the
other hand they place a high demand on computing resources and may lead to
performance problems with slower computers. High refresh values lessen the
demand on computing resources, particular when many signals are being displayed,
but they lead to more erratic display of signal responses. You should
only input a refresh value if your measurement setup places special demands
(high bus load, simultaneous display of many signals, etc.) on the Graphics
window. If the Refresh check box is not checked, the Graphics window automatically
determines a favorable default value. As long as no load problems are
occurring during the measurement you should not modify these options.
If the signal curves run into the right border of the Graphics window after the
start of measurement, this command will result in automatic tracking of the
curves. This involves shifting the time axis to the left, to make room for the
measurement signal on the right side. You can configure this behavior, referred
to as scrolling, in the Graphics window. Continuous scrolling is activated as a
