'''LabChart''' (formerly known as Chart) is a [[data acquisition]] software package produced by [[ADInstruments]]. It functions like a traditional multi-channel [[chart recorder]], [[X–Y plotter]], [[polygraph]] and digital [[voltmeter]]. The software records up to 16 data channels and 32 analysis channels in a single file on computer hard disks. Some data sources can also be controlled using the software.

The software has the ability to control hardware settings, real-time and offline analysis without the loss of raw data, procedure automation via editable macros, and multiple block samplings for the recording and settings of different signals within one file <ref name="macresearch" >{{cite web | last = | first = | authorlink = | coauthors = | title = Showcase: LabChart 6 for Turn-Key Data Acquisition. | page = | work = | publisher = MacResearch | date = | url = http://www.macresearch.org/showcase-labchart-6-turn-key-data-acquisition| accessdate = 2008-12-23 }}</ref>. It has built-in Microsoft digitally signed drivers for use with [[Windows XP]] and [[Windows Vista]] and [[Universal Binary]] software application to support both Intel and Power PC [[Macintosh OS X]].

For more in depth analysis of research studies, specialized modules are available for researchers to

The collected data can be either presented in real-time, i.e. while it is being recorded, or it can be played back later for offline analysis. On screen, that data is presented in a manner that resembles the output of a paper chart recorder, for example as an [[electrocardiogram]] or a [[peristimulus time histogram]]. The application can be automated with macros, and runs on either [[Microsoft Windows]] and [[Apple Macintosh]] systems.
