快速和多变的图形选择
KaleidaGraph提供了各种线条和散点图,包括双y、双x和双xy。这些图支持一个单图中多达20个立的和非立的y变量。其他的图表类型包括统计(框,概率,直方图和百分比),条形图、较坐标、饼图和函数。
完全控制每一个绘图选项
在创建绘图之后,用户可以完全控制所有的绘图元素。Axis选项对话框允许用户控制每个轴的限制、缩放和轴标记,此外还可以显示刻度线和网格线。绘图样式对话框可以用来改变显示绘图的标记类型、大小、颜色和标记的数量。
KaleidaGraph is a thoughtfully designed graphing and data analysis application for research scientists, as well as for those in business and engineering fields. It produces publication-quality graphs, and easily converts the most complex data into a functional display. KaleidaGraph allows the user to import, manipulate, and analyze data, as well as create customized plots. Statistics, linear and nonlinear curve fitting, and the ability to produce precise graphic visualization of data all make KaleidaGraph powerful and flexible.
Flexible Data Entry
When KaleidaGraph is first launched, the user is presented with a data window and formula entry window. Each data window supports a maximum of 1000 columns and 1 million rows. Microsoft Excel files can be opened directly into KaleidaGraph, and users can specify the structure of text files as they are being imported. Pertinent information about the data can be stored using the Posted Note feature of the data window.
The formula entry window provides the ability to manipulate data with a variety of algebraic and statistical functions. These operations can be performed on an entire column of data, a data selection, or a single cell in the data window.
Transpose rows and columns.
Easily reorganize grouped data.
Perform key operations quickly using the Toolbar.
的曲线拟合
曲线拟合领域是KaleidaGraph大的优势之一。KaleidaGraph支持线性和非线性曲线拟合,具有线性、多项式、指数、对数和幂函数的内建方程。提供四条平滑曲线(平滑、加权、三次样条和插值),以帮助改善数据的呈现。
通过KaleidaGraph的一般曲线拟合实现了非线性曲线拟合。这个曲线拟合允许用户定义自己的方程,它可以包含多9个未知参数。该程序载有**过100个不同的方程,可以用来匹配数据。

Complete control over every plot option
After a plot is created, the user has total control over all the plot elements. The Axis Options dialog allows the user to control the limits, scaling, and axis labels for each of the axes, in addition to the display of tick marks and grid lines. The Plot Style dialog can be used to change the marker type, size, color, and number of markers displayed on the plot.
A number of plot tools are available to further customize the plot. A text tool is available to create fully stylized text labels. Drawing tools are provided to add arrows, lines, boxes, ovals, arcs, polygons, and Bezier curves. The identify tool displays the current coordinates each time the mouse is clicked. The data selection tool can be used to graphically eliminate outliers from the plot.
