Strip Chart

Scrolling plot to display streaming data.

Description

Some applications involve streaming data like specimen temperature, patient heart rate or your favorite stock price as a function of time. A strip chart is a useful way to display streaming data. The convention implemented here is that the current time (or other vaiable) is on the far right side. New points are added to the right. Everyhting else shifts to the left. Excess points drop off the left and get discarded. This has the effect of always showing the recent history of a waveform such as voltage versus time.

This utility function is suitable for use in test & measurement applications with the Data Acquisition Toolbox or the Instrument Control Toolbox.

A very nice, well written function to dynamically plot data. Easily adjustable for axis limits and display refresh rate.

Well written and extremely well documented function, which makes it useful not only as a simple tool, but as a starting point for more complex displays.
