能进行自定义方程曲线拟合的软体中，GraphPad Prism的操作最为简便快捷，拟合前参数设置方便，拟合速度快，并支援批量拟合，这在同类软体中非常少见，可以说GraphPad Prism当之无愧为非线性拟合的高手。
Prism 在科学图表的绘製方面可以视为Sigmaplot的替代软体，但是却又包含了简单的试算表，可以直接输入原始数据，软体自动计算标准差和p value，此外，也包含了其他几项数值分析的能力。GraphPad Prism 结合了科学绘图、综合曲线拟合（非线性回归）、可理解的统计数据和数据组织。GraphPad Prism 最初是为医学院和制药公司的实验生物学家设计的，尤其是药理学和生理学领域的实验生物学家。棱镜现在被各种生物学家以及社会和物理科学家更广泛地使用。110 多个国家/地区的 200,000 多名科学家依靠 Prism 来分析、绘制和展示他们的科学数据。它也被本科生和研究生广泛使用。
有效地组织您的数据
与电子表格或其他科学绘图程序不同，Prism 有八种不同类型的数据表，专门针对您要运行的分析进行格式化。这使得正确输入数据、选择合适的分析和创建令人惊叹的图表变得更加容易。
执行正确的分析
避免统计术语。Prism 以清晰的语言提供了一个广泛的分析库，从常见到高度具体——非线性回归、t 检验、非参数比较、单向、双向和三向方差分析、列联表分析、生存分析等等。每个分析都有一个检查表，可帮助您了解所需的统计假设并确认您选择了合适的测试。
随时获得切实可行的帮助
降低统计的复杂性。Prism 的在线帮助超出您的预期。几乎每一步，都可以从在线棱镜指南中访问数千页。浏览图表组合并了解如何制作各种图表类型。教程数据集还可以帮助您了解为什么应该执行某些分析以及如何解释您的结果。
一键式回归分析
没有其他程序可以像 Prism 那样简化曲线拟合。选择一个方程，剩下的工作由 Prism 完成——拟合曲线、显示结果和函数参数表、在图形上绘制曲线并插入未知值。
专注于您的研究，而不是您的软件
无需编码。图形和结果会实时自动更新。对数据和分析的任何更改——添加遗漏的数据、省略错误的数据、更正错别字或更改分析选择——都会立即反映在结果、图表和布局中。
无需编程即可自动化您的工作
减少分析和绘制一组实验的繁琐步骤。通过创建模板、复制系列或克隆图形可以轻松复制您的工作，从而节省您数小时的设置时间。使用 Prism Magic 只需单击一下，即可对一组图形应用一致的外观。
自定义图表的无数方法
专注于数据中的故事，而不是操纵您的软件。Prism 可以轻松创建您想要的图形。选择图形类型，并自定义任何部分——数据的排列方式、数据点的样式、标签、字体、颜色等等。自定义选项是无穷无尽的。

GraphPad Prism combines scientific graphing, comprehensive curve fitting (nonlinear regression), understandable statistics, and data organization. GraphPad Prism was originally designed for experimental biologists in medical schools and drug companies, especially those in pharmacology and physiology. Prism is now used much more broadly by all kinds of biologists, as well as social and physical scientists. More than 200,000 scientists in over 110 countries rely on Prism to analyze, graph and present their scientific data. It is also widely used by undergraduate and graduate students.
Organize Your Data Effectively
Unlike spreadsheets or other scientific graphing programs, Prism has eight different types of data tables specifically formatted for the analyses you want to run. This makes it easier to enter data correctly, choose suitable analyses, and create stunning graphs.
Perform The Right Analysis
Avoid statistical jargon. In clear language, Prism presents an extensive library of analyses from common to highly specific—nonlinear regression, t tests, nonparametric comparisons, one-, two- and three-way ANOVA, analysis of contingency tables, survival analysis, and much more. Each analysis has a checklist to help you understand the required statistical assumptions and confirm you have selected an appropriate test.
Get Actionable Help As You Go
Reduce the complexity of statistics. Prism’s online help goes beyond your expectations. At almost every step, access thousands of pages from the online Prism Guides. Browse the Graph Portfolio and learn how to make a wide range of graph types. Tutorial data sets also help you understand why you should perform certain analyses and how to interpret your results.
One-Click Regression Analysis
No other program simplifies curve fitting like Prism. Select an equation and Prism does the rest—fits the curve, displays a table of results and function parameters, draws the curve on the graph, and interpolates unknown values.
Focus on Your Research, Not Your Software
No coding required. Graphs and results are automatically updated in real time. Any changes to the data and analyses—adding missed data, omitting erroneous data, correcting typos, or changing analysis choices—are reflected in results, graphs, and layouts instantaneously.
Automate Your Work Without Programming
Reduce tedious steps to analyze and graph a set of experiments. It is easy to replicate your work by creating a template, duplicating a family, or cloning a graph—saving you hours of set up time. Apply a consistent look to a set of graphs with one click using Prism Magic.
Countless Ways to Customize Your Graphs
Focus on the story in your data, not manipulating your software. Prism makes it easy to create the graphs you want. Choose the type of graph, and customize any part—how the data is arranged, the style of your data points, labels, fonts, colors, and much more. The customization options are endless.
