MagicPlot is used for scientific and engineering data analysis, graphing, nonlinear curve fitting, and multi-peak fitting. The Pro version program has publication quality customizable plots with multiple axes, text table import with previews, data manipulation, FFT, integration, differentiation, histograms, and other statistics, with multiple undos (some of these features are on the free student version as well).
Kaleidagraph Curve Fitting Software 14
pro Fit is a data analysis and plotting software package from QuantumSoft. Dave [not me] wrote: "...it has an extensive Applescript dictionary, ability to handle large data sets well (I've done graphs with hundreds of thousands of points), can be extended by writing plug ins or adding formulas that you create, does great curve fitting. I consider it much more feature complete than Kaliedagraph and far more intuitive than Igor Pro. They have excellent customer support, usually getting back to you within 24 hours if you have a bug report or feature request." We have observed that ProFit is frequently updated which indicates it is well supported (2010).
Version 6.1 changes: now Universal Binary; new tool for multidimensional curve fitting; revamped rendering engine for plots with native Core Graphics, PDF, and PostScript support; additions to the scripting language; more. Version 6.2: Python support, extended fitting, more data processing, higher performance.
Lance Bland, the developer, wrote: "In addition to all the standard features, Vvidget includes advanced features such as floating ticks, curves that can extend beyond the graph frame or can be truncated and literally hundreds of tunable parameters. 3D types rotate in real time and even the graph labels can be rotated in their own plane, independent of the main graph rotation. Data can be inserted through a list of numbers or by point and click methods." The same developer provides software such as QuadraticLab for other math functions. The software appears to be under very active development.
Samples (1.5 mL) were individually subjected to temperature titrations with 1C intervals separated by 1 minute equilibration periods. Data collection occurred in a sealed 4-mL Hellma quartz cuvette using a FluoroMax-3 (Jorbin Yvon Horiba) fluorometer with a Wavelength Electronics Model LFI-3751 temperature controller. Excitation occurred at 280 nm (slit width 3.5 nm), and emission scans were collected from 295 to 397 nm (slit width 7 nm) in 2 nm increments with 0.5 s of integration time and then converted into scan centres of mass. KaleidaGraph (Synergy Software) was used for curve fitting to a standard temperature melt equation. Details on data reduction and curve fitting are provided in Additional file 3.
pro Fit is a macOS application for data/function analysis, plotting, and curve fitting. It is used by scientists, engineers and students to analyze their measurements and the mathematical models they use to describe them.
KaleidaGraph is an award-winning graphing and data analysis solution that is rich in features yet affordably priced. This unique application distinguishes itself in the technical marketplace with its powerful curve fitting, precise plot customization, helpful stats, a short learning curve and an affordable price.
Hi Matt, nice article and I appreciate your comments regarding plotting and graphing software. I agree, its tough to find a quality program for minimal cost. One of the biggest problems I see is the learning curve associated with different software applications.
\(\rmb=K_d+[^\rmFI\rmI\rmRE \mbox- \rmRNA]+[\rmIRP1]\), where robs is the observed anisotropy at any point in the titration curve, rmin is the minimum observed anisotropy in the absence of IRP1 protein, and rmax is the maximum anisotropy at saturation; [FIIRE-RNA] and [IRP1] are the concentrations of these components. K d is the equilibrium dissociation constant. KaleidaGraph software (version 2.1.3; Abelbeck Software) was used to obtain the K d values and standard errors for parameters using nonlinear least square fitting of the data. For all equilibrium measurements, three independent titration experiments were performed, and the value reported is the average.
Temperature dependent stopped-flow traces representing binding of FRT IRE-RNA or ACO2 IRE-RNA with IRP1 protein were analyzed using a curve-fitting program, Global analysis software as described previously47, 50, 51. Data were fit to the single-exponential functions. Fitted curves correspond to the following single-exponential equation, 2ff7e9595c
