This means that if two vectors point in the same (or exactly opposite) direction, then their cross product will be zero. If the resultant is \( \textbf \) lie in. The components of each vector are added together. The first of these is the resultant, and this is obtained when The demo also has the ability to plot 3 other vectors which can be computed from the first two input vectors. Clicking on the end of a vector will also reveal its individual components. You can drag the diagram around and zoom in or out by scrolling with the mouse. Of the diagram will automatically adjust to fit the magnitude of the vectors). Clicking the draw button will then display the vectors on the diagram (the scale GraphSketcher: It is a lightweight and certainly less powerful application than DataGraph (see this review in the JSS), but it allows to quickly generate basic graphical displays.The demo above allows you to enter up to three vectors in the form (x,y,z). (There may be other options that I haven’t tried yet.) For PDF to text conversion, I have used pdftotext in the past, but it is not really useful when it comes to extract data from Tables with complex layout. Although the final page layout is sometimes not so satisfactory, all text and Tables get properly rendered. GraphSketcher is a simple, elegant tool for quickly sketching graphs and plotting data but you don’t even need data to get started. PDF to Word +: This is a small App (with a small price too) that I found useful to convert a whole LaTeX document (converted to PDF) to a Word version for proof-reading by some of my co-authors. The themes are gorgeous, of course, but what is really worth a feature is the possibility to use it as a ‘slide sorter’ while writing in your favorite text editor (this is its best definition, IMHO). The latest version features MathJax equations, custom footer, and footnotes. Here is what I currently have in my navigation toolbar:ĭeckset: I already talked about this new App, and I found myself using it two times to prepare some slideshow in recent months. Although it is just a point-and-click software, it is definitively worth a try (and if you have R or StatTransfer, no need to buy the Pro version).ĭash: I installed it as soon as I got my new Macbook, and even if I’m not using it as probably a programmer does I find it very useful to replace man pages and Google. It supports many data formats, including proprietary ones like MS Excel/Apple Numbers, SPSS, Stata, or SAS (see this repository on GitHub). It is pretty fast to display univariate distribution, apply filters and build pivot Tables. I really recommend this software to perform basic exploratory data analysis or to assess data quality. If that doesnt suit you, our users have ranked more than 25 alternatives to GnuPlot and seven of them are available for iPad so hopefully you can find a suitable replacement. I was wrong since I now purchased the latest version on the App Store and used it extensively in parallel with R or Stata to process and clean messy databases. Wizard: I reviewed this statistical package some time ago, and although I felt like it has a good design it wouldn’t of much help for my daily work. The numbers can be read on the screen, and written or copied to a spreadsheet. The image file can come from a scanner, digital camera, or screenshot. Basically, it is a way to organize and annotate screenshots using a simple UI. Engauge Digitizer is an open-source digitizing app that converts an image file which shows a graph or map into numbers. These are mostly small packages that do one thing well and allows text-based approaches for many of them, as in Unix philosophy.Ĭlarify: I prepared a very basic tutorial on RStudio with it (this is still work in progress at the time of this writing), shortly after I came across this software on Brett Perpstra’s weblog. Free Open Source Mac iPad GraphSketcher info, screenshots & reviews Alternatives to GraphSketcher What is GraphSketcher OmniGraphSketcher helps you make elegant and precise graphs in seconds, whether you have specific data to visualize or you just have a concept to explain. Here are some Mac Apps that I found using more and more often.Īlthough I’m still keeping a text-based workflow, where I spend most of the days using Emacs and a terminal, I recently installed or reinstalled some nice Apps when I got my new Macbook Pro in July. GraphSketcher A fast, simple graph drawing and data plotting app.
