Graphing and Trending

The standard DAQFactory components offer many different tools for creating your own custom user interface displaying your data in real time. But the current state of your system is often not as useful as the state of your system over time. To view long term trends in your data you need to create some graphs. You can place trend graphs on any of your screens along with the other components. These graphs can display Y vs Time trends, or X vs Y comparisons. You can create as many traces as you may need on up to 12 different Y axes.

Traces use expressions too, so there's no need to precalculate the values you would like to graph. If you want to plot Sin(PumpRotation^2) / PumpSpeed vs. Log(TankPressure) you simply enter these two expressions.

Since graphs reference back to channels and their history, you can create or edit graphs on the fly and they will immediately display the appropriate data. They do not have to sit and collect data to be displayed first.

Graphs offer many features for displaying your data including error bars, wind barbs, axis, line and bound annotations, and colorization of a trace based on an expression. Graph markers can be used to identify points and quickly analyze peaks in your data. DAQFactory creates the graphs in a background process, so even the most complicated graphs won't make DAQFactory sluggish.

The full power of DAQFactory's graphs is hard to describe without actually creating some, so we suggest downloading a copy of DAQFactory and giving them a try!
