yoshinoGRAPH is a scientific graph software for data analysis and presentation. You can make 2D and 3D graphs quickly from data files in text format. This software is tiny but includes many basic functions to analyze/edit data as well as rather advanced ones.
Harukazu YOSHINO (Osaka, Japan): " yoshinoGRAPH has been developed just for myself to handle data of transport phenomena of organic conductors but I wish it also assists you to pursue your own research."

Features:
* easy to make sientific graphs for presentation and publication
* plot styles: scatter charts, density and 3D plots
* special 2D plots: density, double y-axis, shift data along y-direction with z values
* easy to change scales among linear, log, inverse and reverse
* auto fitting: polynomial, 3rd spline, Gaussian and other arbitrary functions
* manual fitting with two independent lines
* easy to remove scattered/noisy data
* many functios to convert data: quick sort, numerical differentiation, smoothing, making tables, convert with mathematical expressions and so on
* to draw a math function on 2D graph using an expression
* to copy a graph in metafile and bitmap formats to paste it on a presentation software
* easy to read many data files saved in different folders

System requirement
- OS
Windows 7(SP1 32&64bit)/Server 2008 R2(SP1 64bit)/Vista(SP2/SP1 32&64bit)/Server 2003 R2(SP2)/XP(SP3) yoshinoGRAPH itself is a 32-bit application.
- Software
yoshinoGRAPH is being developed by using Microsoft Visual C# 2010. So Microsoft .NET Framework 4.0 is needed, or one is instructed to install it just after running yoshinoGRAPH installer.
- Display
1024x768 or wider is recommended.
- The opacity option of the "plot-range-select" window as well as the 3D-density plot is effective on Windows XP or later.
