One of the powerful features of DAQFactory is expressions. Expressions are calculations that you can use in various places throughout DAQFactory: just about any place you need a number and many places you need a string. Expressions can be as simple as a constant or as complex as you need, acting on single data points or arrays of points.
When entering expressions, DAQFactory provides syntax coloring and an intelligent drop down box that displays channels, formulas and other things you may want to use in your expression so you do not have to remember everything. Any edit box within DAQFactory that displays in color and some that do not can take an expression. Expressions are used to display calculated values, to graph calculations, to set ranges, to control data logging, and in many other locations.
