GeoXDraw (formerly Tikazu) is a Windows95+ (98, 2000, ...) program for the treatment of geochemical data, and their interpretation through graphic representations.
The program is directly downloadable from http://jacques.moutte.free.fr/zip/geoxdraw_.zip (or geoxdraw_zip.exe, 'self-extractable').
Downloading the file GeoXDraw.zip (360 K) and decompressing into a given directory (e.g. c:\GeoXDraw) will create the program GeoXDraw.exe, and related text files for configuration (_GeoXDraw.log, _spiders.txt) and test (_colsym.txt and _xy.txt).
No need for import/export to a specific format. Copy the data from your favorite spreadsheet program, and directly paste within the input window of GeoXDraw. In order to allow many different 'projections' from different points of view, the input file can include up to eight descriptive fields which will be used to define the selections (to plot or not), and the colors and shapes of the symbols. GeoXDraw can work on one single input file for X-Y-(Z), or with two input files, one for X (- Z), the other for Y, or one for sample list and the other for data.
Obective: to implement tasks that are specific to geochemical data (e.g. ternary diagrams, switching from weight to atomic coordinates, ...). GeoXDraw includes most basic tools specific to geochemical data handling ; on the other hand the user will rely, for more general tasks, on more common softwares (one for spreadsheet and one for drawing). GeoXDraw is not so complete as other softwares specially designed for geochemical data (for example it does not include ready-made geochemical diagrams with already defined fields for reference series); as a consequence, it is compact : about 650 kbytes, in a single .EXE file, easy to install / uninstall (no external DLL files).
Main graphic functions :
Other functions : conversions (e.g. weight to atomic proportions, ppm to oxyde %, ...), structural formulas. Converted data in tab-delimited files directly read by spreadsheet.
Exportation : the diagrams can be either pasted to the clipboard for immediate use in other windows software, or (better) saved as PostScript text files, which can be used directly, inserted into a larger PostScript or LaTeX file, or imported into word processsing or graphic softwares for further processing (publishing, printing, ...)
