Kst is a plotting and data viewing program. It is a general purpose plotting software program that evolved out of a need to visualize and analyze astronomical data, but has also found subsequent use in the real time display of graphical information. Kst is a KDE application and is freely available for anyone to download and use under the terms of the GPL. It is noted for being able to graph real-time data acquisition.
History
[edit | edit source]Kst was initially developed by Barth Netterfield, an astrophysicist as a personal project. By 2004 it had begun to be used in various universities and the European Space Agency and development was funded by the Canadian Space Agency.[1] Kst is written in C++ and based upon (but does not use) the Tk toolkit.[2] It is targeted towards large (million element) data sets.[3]
Features
[edit | edit source]kst is a fast real-time large-dataset plotting and viewing tool with basic data analysis functionality.[4][5][6]
Plot types
[edit | edit source]kst is able to plot histograms and 3-D with color and contour mapping for 3-D images.[7] It is also able to process Network Common Data Form (NETCDF) files for 2-d plotting[8]
Real-time plotting capability
[edit | edit source]Kst has been chosen where there is a need to present plots in real-time.[9]
Applications
[edit | edit source]Real-time applications vary in size from simple graphing of a sensor from a microcontroller such as arduino that may be set up by a hobbyist to a simple sensor[4] to plotting of real time date from the Atacama Cosmology Telescope.[10] The program has been recommended for real time graphical display of an open energy monitoring project.[11][12]
Inputs
[edit | edit source]Kst is able to accept a number input formats with Dirfiles being particularly suitable for streaming applications[10][13] and plug-in extension filters enabling other input stream types and file formats to be added.[7]
Scripting language
[edit | edit source]The tool offers a scripting language, termed KstScript based upon JavaScript syntax which can help automate workflows.[7]
Alternatives
[edit | edit source]Some alternatives include MATLAB, Qtiplot, SciDAVis, Grace and LabPlot.[6] However, some of these are part of a numerical analysis package.[6]
Spin-off developments
[edit | edit source]Dirfile format
[edit | edit source]In the process of developing the kst application a spin-off was the emergence of the Dirfile file format standard for time-ordered binary data in an efficient manner.[a] It was developed under the Getdata project into an independent standard with its own API.[13]
