Publisher Description
GNUplot37 is a version of GNUplot 3.7.3, a popular open-source math-graphics and plotting package. It can generate accurate visualizations of mathematical functions, as well as creating multi-colour plots of existing data series. It is a more advanced version of the GNUplot 3.2 that was the companion product to GEMESYS sAPL, an APL Language environment for the Blackberry Playbook. GNUplot37 can plot time-series data, such as stock-prices or other financial variables, such as economic indexes, interest-rates series, or money-supply values. It can also be used as a visualization tool to support learning basic and advanced mathematics. Students can enter simple plotting commands, such as "plot sin(x)", and generate an immediate visual image of the function. GNUplot is a robust, well-documented open-source product which has been around for many years, and allows complete control graphics generation and display on a wide variety of platforms. GEMESYS Software is pleased to bring this well-known workhorse to the Android platform as part of our commitment to the open-source development model. This version makes use of the DOSbox emulation environment, and has been tested to ensure numerical accuracy. Enhancements to the mathematical capabilities of DOSbox (which will be made available soon as "gDosBox") were made to ensure the operational accuracy of GNUplot37.
Plots that appear on the screen, can be copied to Android clipboard by taking a screen-shot. On Android 4.1, that is a button on screen bottom, but on Android 4.2.2 (the Samsung Galaxy Tab3) and Android 5.0.2 (Galaxy Tab-A), you press power-button plus front-screen button. Or, you can set options within GNUplot to output the plot results to a .gif file, and transfer that file to another location, using any of the numerous communication methods available to Android users.
Enjoy!
*** GNUplot37 now runs on Android-5 ! The change involved re-coding jobject pointers that were local static to use the NewGlobalRef feature, first documented in Android ICS (Ice Cream Sandwich), and now part of the new ART (Android Run Time engine) in Android 5 (Lollipop) devices. GNUplot37 users are encourged to forward operation reports to our email address. Current testing has been limited to Android 5.0.2 tablets, including Samsung Galaxy Tab-A, Tab-3 and Tab-4.
