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. Features: plot styles: scatter charts, density and 3D plots with options a lot of color, symbol and other style options double y-axis and shift in y direction are available in 2D graph easy to read many data files saved in different folders easy to change scales among linear, log and inverse easy to convert data using many mathematical functions easy to remove scattered/noisy points in experimental data easy to write axis labels and other texts numerical differentiation and integration of data quick sort of data smoothing and roughening of data calculating difference and ratio between two series of data making tables with an equal interval in several ways manual fit of two independent lines to a data curve least-squares fit to power polynomials least-squares fit to Chebyshev, Legendre and Fourier polynomials least-squares fit to 3rd spline curves non-linear fit to Gaussian curves non-linear fit to arbitrary functions with 10 parameters Fourier transform using FFT, DFT and numerical integral to draw a math function on 2D graph using an expression to copy graphs as extended-metafile and bitmap formats to clipboard and files to print hard copies of graphs yoshinoGRAPH has been developed for myself as well as my students to handle data of transport phenomena of organic conductors, but I wish it also assists you to proceed your own research.
