The change is immediately graphed and if you move your cursor off the panel then it becomes transparent and you can see the effect of your changes without leaving the panel. SigmaPlot takes you beyond simple spreadsheets to help you show off your work clearly and precisely.

With SigmaPlot, you can produce high-quality graphs without spending hours in front of a computer. The user interface also includes Microsoft Office style ribbon controls. And the tabbed window interface efficiently organizes your worksheets and graphs for easy selection. And these tabs may be organized into either vertical or horizontal tab groups. Graph Gallery and Notebook Manger panes may be moved to any position and easily placed using docking panel guides.

You can add frequently used objects to the Quick Access Toolbar. Take advantage of ribbon collections of common properties, tabbed selection of graphs, worksheets and reports, right mouse button support and graph preferences.

The interactive Graph Wizard leads you through every step of graph creation. You get compelling, publication-quality charts and graphs in no time. SigmaPlot offers more options for charting, modeling and graphing your technical data than any other graphics software package. Compare and contrast trends in your data by creating multiple axes per graph, multiple graphs per page and multiple pages per worksheet. From simple 2-D scatter plots to compelling contour and the new radar and dot density plots, SigmaPlot gives you the exact technical graph type you need for your demanding research.

And, to help you see interactions in your 3-D data, SigmaPlot powerfully renders multiple intersecting 3-D meshes with hidden line removal. With so many different chart and graph types to choose from, you can always find the best visual representation of your data. SigmaPlot offers the flexibility to customize every detail of your graph. You can add axis breaks, standard or asymmetric error bars and symbols; change colors, fonts, line thickness and more. Double-click on any graph element to launch the Graph Properties dialog box.

Modify your graph, chart or diagram further by pasting an equation, symbol, map, picture, illustration or other image into your presentation. Save all of the attributes of your favorite graph style in the Graph Style Gallery. Add greater speed and efficiency to your analysis by quickly recalling an existing graph type you need and applying its style to your current dataset. In the Notebook Manager, you can copy and paste a graph from one worksheet to another and all the attributes of that graph are applied to the new data saving much time.

Create stunning slides, display your graphs in reports or further customize your graphs in drawing packages. Then, just double click your graph to edit directly inside your document.

Quickly send your high-resolution graphs online to share with others. Viewers can explore data used to create vector graphs and zoom, pan or print images at any resolution directly from a Web Browser. Automatically generate active Web objects from your graphs or embed the objects within other Web pages.

SigmaPlot provides all the fundamental tools you need to analyze your data from basic statistics to advanced mathematical calculations. You can fit a curve or plot a function and get a report of the results in seconds.

Use built-in transforms to massage your data and create a unique chart, diagram or figure. Access SigmaPlot right from your active Microsoft Excel worksheet. Use Excel in-cell formulas, pivot tables, macros and date or time formats without worry.

Keep your data and graphs in one convenient file. Generate simulated data or modify worksheet columns of data with transforms.

Create simple one-line transforms with the Quick Transforms feature that walks you through transform implementation. Or create extremely complex transforms with hundreds of lines of code. Fitting your data is easy with the SigmaPlot Regression Wizard. The Regression Wizard automatically determines your initial parameters, writes a statistical report, saves your equation to your SigmaPlot Notebook, and adds your results to existing graphs or creates a new one!

You can even add your own curve fit equations and add them to the Regression Wizard. The Dynamic Curve Fitter performs or more curve fits using your equation and data starting from optimally different initial starting values. The results are ranked by goodness of fit so that you can check the top ranked results against the result you obtained from the Regression Wizard. For many simple equations, which are fit to data sets with a sufficiently large number of data points, the Dynamic Curve Fitter finds the same result as the Regression Wizard.

But the problem is that the user simply does not know whether the solution found by the Regression Wizard is the best possible or not. So there is always a concern that the correct solution has not been found. Dynamic fitting minimizes this concern. Its use is encouraged prior to publishing results particularly if a complicated equation is used.

Global curve fitting is used when you want to fit an equation to several data sets simultaneously. The selected equation must have exactly one independent variable. The data sets can be selected from a worksheet or a graph using a variety of data formats.

You can also specify the behavior of each equation parameter with respect to the data sets. A parameter can be localized to have a separate value for each data set, or a parameter can be shared to have the same value for all data sets.

The main difference is the extra panel shown below for specifying the shared parameters. Plotting user-defined and parameterized equations is only a mouseclick away with the Plot Equation feature. Just type the function or select one from the built-in library and specify the parameters and the range.

Create your own built-in functions and save them for future use. Plot functions on new or existing graphs or plot multiple functions simultaneously using different parameter values. Save plotted X and Y results to the worksheet. SigmaPlot has import file formats for all common text files. This includes a general purpose ASCII file importer which allows importing comma delimited files and user-selected delimiters.

Plus all Excel formats may be imported. Axon binary and text electrophysiology files may be imported. Import any ODBC compliant database. Excel and Access database files are supported. Run SQL queries on tables and selectively import information. Not a programmer? No problem. With SigmaPlot, you can record macros by point-and-click with the macro recorder. Use macros to acquire your data, execute powerful analytical methods, and create industry-specific or field-specific graphs. Use one of the thirty built-in macros as provided or use these macros as a base to quickly create your own macros.

Share the power of SigmaPlot with less-experienced users by using macros to tailor the SigmaPlot interface for your particular application. Create custom dialog boxes, menu choices and forms to help guide novice users through a session. Analyze and graph your data using SigmaPlot within those applications. SigmaPlot provides more than different 2-D and 3-D graph types. From simple 2-D scatter plots to compelling contour, Forest and radar plots, SigmaPlot gives you the exact technical graph type you need for your demanding research.

With so many options, you can always find the best visual representation of your data. SigmaPlot now offers almost 50 of the most frequently used statistical tests in scientific research by integrating SigmaStat into one application. Suggestion of the most appropriate statistical tests is offered by a software-based Advisor. Raw and indexed data formats are accepted to avoid data reformatting. Violation of data assumptions is checked in the background and, if true, the correct test to use is recommended.

Reports with descriptive interpretations are generated and graphs specific to each test may be created. SigmaPlot now employs an all new user interface allowing users to easily setup a global curve fit. This gives users the ability to easily share one or more equation parameters across multiple data sets. Non-linear curve fitting is known to produce incorrect results in some instances. Dynamic Curve Fitting is designed to determine if this has happened and if so what the likely best fit is.

SigmaPlot is now a complete graphing AND an advisory statistics suite. All of the advanced statistical analysis features found in the package known as SigmaStat have now been incorporated into SigmaPlot along with several new statistical features. SigmaPlot guides users through every step of the analysis and performs powerful statistical analysis without the user being a statistical expert.

In addition to the EC50 value already computed, the user can also compute other user-entered EC values such as EC40 and EC60 and compute them instantly. Two five-parameter logistic functions have also been added and the Dynamic Curve Fitting feature included to help solve difficult curve fitting problems. In earlier versions of SigmaPlot, almost all objects in a 2D graph were selectable with just a mouse click.

However, almost all objects in a 3D graph were not. SigmaPlot now adds mouse selectability of all 3D graph objects with the ability to customize all 3D objects. Viewers can explore data used to create graphs and zoom, pan or print images at full resolution directly from a Web Browser.

Each worksheet can hold a list of user defined transforms that will automatically be re-run whenever the transform input data has changed. SigmaPlot lets the user select a graph first and then gives you a pre-formatted worksheet to structure their data.

The data entered into the worksheet is immediately displayed on the graph. This feature can demonstrate to you the strong relationship between the data format and the graph type.

Just double click your graph to edit directly inside your document.

It is the raw information from which statistics are created. Statistics are the results of data analysis - its interpretation and presentation. In other words some computation has taken place that provides some understanding of what the data means. Both statistics and data are frequently used in scholarly research. Statistics are often reported by government agencies - for example, unemployment statistics or educational literacy statistics. Often these types of statistics are referred to as 'statistical data'.

Thus, graph theory has more practical application particulars in solving electric network. No matter if, we adopt new analytical methods or technical means, we must have a distinct recognition of electric power system itself and its complexity, and increase analysis continuously, operation and control level. It reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. Computer and software engineers apply graph theory as algorithms and computations. As power distribution systems can be very large, containing even hundreds of thousands of substations, it can be argued that the graph has to be broken down into smaller components which are then visualized separately and then assembled by use of the genetic algorithm. In electrical engineering, graph theory is applied in communication networks and coding theory. Abstract Our object is threefold: to develop a basic theory of flow graphs; to extend their known application to electrical networks; and to formulate the natural relation between Don't show me this again.

One goal of statistics is to present data in a meaningful way. This is far too many to print out in a journal article or sidebar of a magazine story. That's where graphs can be invaluable, allowing statisticians to provide a visual interpretation of complex numerical stories. Seven types of graphs are commonly used in statistics. Good graphs convey information quickly and easily to the user. Graphs highlight the salient features of the data.

The proper understanding and use of statistical tools are essential to the scientific enterprise. This is true both at the level of designing one's own experiments as well as for critically evaluating studies carried out by others. Unfortunately, many researchers who are otherwise rigorous and thoughtful in their scientific approach lack sufficient knowledge of this field. This methods chapter is written with such individuals in mind.

In statistics , a misleading graph , also known as a distorted graph , is a graph that misrepresents data , constituting a misuse of statistics and with the result that an incorrect conclusion may be derived from it. Graphs may be misleading through being excessively complex or poorly constructed. Even when constructed to accurately display the characteristics of their data, graphs can be subject to different interpretation, or unintended kind of data can seemingly and ultimately erroneously be derived. Misleading graphs may be created intentionally to hinder the proper interpretation of data or accidentally due to unfamiliarity with graphing software , misinterpretation of data, or because data cannot be accurately conveyed. Misleading graphs are often used in false advertising. One of the first authors to write about misleading graphs was Darrell Huff , publisher of the book How to Lie with Statistics. The field of data visualization describes ways to present information that avoids creating misleading graphs.

С подружкой. Немец был не. Клушар кивнул: - Со спутницей. Роскошной рыжеволосой девицей. Мой Бог. Это была настоящая красотка.

Тут все без обмана. Он стоит десять раз по двадцать миллионов. - Увы, - сказал Нуматака, которому уже наскучило играть, - мы оба знаем, что Танкадо этого так не оставит.

- Что он хочет этим сказать. - Четыре на шестнадцать, - повторил профессор. - Лично я проходил это в четвертом классе. Сьюзан вспомнила стандартную школьную таблицу.

ME TOO, что означало: Я. Беккер расхохотался. Он дожил до тридцати пяти лет, а сердце у него прыгало, как у влюбленного мальчишки. Никогда еще его не влекло ни к одной женщине. Изящные европейские черты лица и карие глаза делали Сьюзан похожей на модель, рекламирующую косметику Эсте Лаудер.

Сьюзан поднялась на верхнюю ступеньку лестницы. Она не успела постучать, как заверещал электронный дверной замок. Дверь открылась, и коммандер помахал ей рукой. - Спасибо, что пришла, Сьюзан. Я тебе очень благодарен.
