Introduction
Welcome to the world of yoshinoGRAPH!!!
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. Followings are some features of yoshinoGRAPH
free
plot styles: scatter charts, density and 3D plots with options
a lot of color, symbol and other style options
double yaxis 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
leastsquares fit to power polynomials
leastsquares fit to Chebyshev, Legendre and Fourier polynomials
leastsquares fit to 3rd spline curves
nonlinear fit to Gaussian curves
nonlinear 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 extendedmetafile 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.
