Instead, I’ll start by showing a basic PowerShell-integration. The existing teaching material on GnuPlot is so good that it would be silly to attempt to add to it. It likes columnar or tab-separated data, which suits SQL Server.Īlthough GnuPlot is best known for plotting scientific data and mathematical expressions, it is excellent in business, particularly for financial data. GnuPlot runs a script, and generally the data is read from a data file specified by the script in the plot command. Python, Java, Ruby, Haskell Fortran 95 and Smalltalk all have libraries for accessing Gnuplot.Īnother great advantage of GnuPlot is that allows the separation of script from data. ![]() So many impoverished scientists, with antique output devices, have been accommodated over the years and have blessed Gnuplot’s ability to produce graphs on just about any printer. It does that as well, but also in vector graphics or as a Pdf. ![]() Most of us nowadays want graphs as bitmapped graphics to display within a webpage or embed in a document. It can draw plots onscreen, even in ASCII. GnuPlot is one of the last of the applications that can use a classic vector-based pen plotter as easily as a laser printer. It is a tool for the professional, and isn’t really suitable for fancy graphs in PowerPoint presentations. It covers a vast range of graph types and there are a large number of samples and tutorials around. GnuPlot has been cherished and developed mainly for scientific graphs, but it is very versatile. If anything, the standard of graphs have deteriorated since then as the tools have become more commoditised. You’d have thought that these were primitive times for graphs, but no, they weren’t. ![]() GnuPlot, which runs under a free software license, has its origins in the nineteen eighties. If you haven’t heard of Gnuplot, it is the standard way of plotting scientific data which works via the command-line and uses a domain-specific scripting language (DSL), and there are two books, along with countless samples, tutorials and articles about using it. If I had to learn just one though, I’d use GnuPlot because it is so versatile. There are many R libraries for example, there is Reporting Services, Plotly or PowerBI. There are many excellent ways of plotting data from SQL Server databases.
