Solution
NI charts, in both LabVIEW and Measurement Studio, have three different modes to scroll data. These three update modes are
Strip Chart,
Scope Chart, and
Sweep Chart.
- Strip Chart: This mode has a scrolling display that is similar to a paper tape strip chart recorder. This mode first plots values from left to right. From here, it continues to plot new points at the rightmost point and shifts old values to the left.
- Scope Chart: This mode has a retracing display similar to an oscilloscope. As it receives each new value, it plots the value to the right of the last value. When the plot reaches the right border of the plotting area, it erases the plot and begins plotting again from the left border.
- Sweep Chart: This mode acts much like the scope chart, but the plot is not erased when the plot hits the right border. Instead, a moving vertical line marks the beginning of new data and moves across the display from left to right as it adds new data.
These update modes can be configured using chart properties. To do this, right-click on the chart indicator and select
Properties » Appearance; select the
Update Mode pull down menu and select
Strip Chart, Scope Chart, or Sweep Chart.
