ubuntu中的origin——qtiplot

由于要用的origin，切换的window中比较不方便，故找了下linux中的作图软件。
常用的似乎有gnuplot，但是这是基于命令行的，对我来讲似乎还要求高了点。
所以找了下qtiplot，界面看了下，和origin差不多。

下面是其的一点特性（大概翻译一下）：

• QtiPlot is cross-platform: it works on all systems supported by Qt, including Windows, Linux/Unix and Mac OS X systems.（跨平台，支持windows，linux，mac）
• QtiPlot is fully scriptable via Python, which gives you the possibility to use powerfull existing scientific tools, such as SciPy, thus bringing unlimited data analysis power.（支持python，这样可以带来更强大无限制的数据处理，在origin 中是对origin c支持，也是刚接触origin的，因此当时也眉宇用到origin c进行扩展之类的）
• OpenGL based 3D plotting: height maps, user defined functions and parametric surfaces.（3d作图基于OpenGL）
• Publication quality 2D plots: Error Bars, Multilayer Plots, Bar Plots, Pie Plots, Vector Plots, Contour and Image Plots.（发表质量的2D作图效果）
• Statistical Plots: Box/Whiskers Diagramms, Histograms.（统计作图）
• Easy export of plots to vector formats (EPS, PS, PDF, SVG) and to various raster image formats (BMP, JPG, PNG, TIFF etc ...)（能够很容易的导出图形，保存为矢量或者是点状）
• Powerful and versatile spreadsheets and calculations in column-logic.（强大的表和列的逻辑计算功能）
• Easy ASCII-Import/Export of single or multiple files.（可以很容易导出为ASCII文件）
• Linear and nonlinear curve fitting with weighting and estimation of statistical errors of the fit-parameters. The accuracy of QtiPlot can be verified with the Statistical Reference Datasets Project of the National Institute of Standards and Technology (NIST).（线性和非线性拟合）
• Multi-peak fitting with Gaussian and Lorentzian peak profiles.（峰拟合）
• Built-in data analysis routines: statistics, sorting, FFT, data smoothing (Savitzky-Golay, FFT smoothing, and moving window average), data filtering (low/high/band pass and band block filters), convolution/deconvolution, correlation, interpolation, numerical integration/differentiation, etc...
• Matrices optimized for image analysis.（内置的强大的数据分析）
• Templates support: all the settings for plots (2D/3D), tables and matrices can be saved to ASCII files and restored later on for a fast editing process.（支持模板）
• Project files based on folders, a powerful project explorer with extensive built-in features: drag and drop, searching facilities, etc...（基于项目的文件夹管理）
• Import of Origin 7.5 files.（能够导入origin 7.5的文件）
