A cosa serve SigmaPlot

SigmaPlot aiuta a creare rapidamente grafici accurati

Con la nuova interfaccia grafica delle proprietà è possibile selezionare la categoria di proprietà nell’albero a sinistra e quindi modificare le proprietà a destra. La modifica viene immediatamente graficata e se si sposta il cursore dal pannello, questo diventa trasparente e si può vedere l’effetto delle modifiche senza uscire dal pannello.

La procedura “seleziona a sinistra e cambia a destra” rende la modifica dei grafici facile e veloce. SigmaPlot vi porta oltre i semplici fogli di calcolo per aiutarvi a mostrare il vostro lavoro in modo chiaro e preciso. Con SigmaPlot potete produrre grafici di alta qualità senza passare ore davanti al computer. SigmaPlot offre una perfetta integrazione con Microsoft Office®, per cui è possibile accedere facilmente ai dati dei fogli di calcolo di Microsoft Excel® e presentare i risultati in presentazioni di Microsoft PowerPoint®.

L’interfaccia utente include anche controlli a nastro in stile Microsoft Office. L’interfaccia della finestra a schede organizza in modo efficiente i fogli di lavoro e i grafici per facilitarne la selezione. Le schede possono essere organizzate in gruppi di schede verticali o orizzontali. I riquadri di Graph Gallery e Notebook Manger possono essere spostati in qualsiasi posizione e posizionati facilmente grazie alle guide del pannello di aggancio. È possibile aggiungere oggetti di uso frequente alla “Quick Access Toolbar”. Ad esempio, si possono aggiungere le opzioni Salva blocco note, Chiudi tutto, Aggiorna pagina grafica e Modifica tracciato.

Più di 100 tipi di grafici tecnici 2D e 3D

Dai semplici grafici di dispersione 2D agli avvincenti grafici a contorno e ai nuovi grafici radar e a densità di punti, SigmaPlot vi offre l’esatto tipo di grafico tecnico di cui avete bisogno per le vostre ricerche più impegnative. Inoltre, per aiutarvi a vedere le interazioni tra i vostri dati in 3D, SigmaPlot è in grado di renderizzare più maglie tridimensionali intersecanti con la rimozione delle linee nascoste. Con così tanti tipi di grafici e diagrammi tra cui scegliere, potrete sempre trovare la migliore rappresentazione visiva dei vostri dati.

Utilizzate il Global Curve Fitting per analizzare simultaneamente più dati.

il Global Curve Fitting viene utilizzato quando si desidera adattare un’equazione a più serie di dati contemporaneamente. L’equazione selezionata deve avere esattamente una variabile indipendente. I set di dati possono essere selezionati da un foglio di lavoro o da un grafico, utilizzando una varietà di formati di dati. È inoltre possibile specificare il comportamento di ciascun parametro dell’equazione rispetto ai set di dati. Un parametro può essere localizzato per avere un valore separato per ogni set di dati, oppure può essere condiviso per avere lo stesso valore per tutti i set di dati.

La procedura guidata per il Global Curve Fitting è molto simile alle procedure guidate per la regressione e l’adattamento dinamico per quanto riguarda la struttura e il funzionamento. La differenza principale è il pannello aggiuntivo mostrato di seguito per specificare i parametri condivisi.

Ottenere dati da quasi tutte le fonti

SigmaPlot dispone di formati di importazione per tutti i più comuni file di testo. Tra questi, un importatore di file ASCII di uso generale che consente di importare file delimitati da virgole e delimitatori selezionati dall’utente. Inoltre, è possibile importare tutti i formati di Excel. I formati di input dei dati SPSS, Minitab, SYSTAT e SAS sono supportati da SigmaPlot.

È possibile importare file elettrofisiologici binari e di testo di Axon. Inoltre, il modulo Elettrofisiologia, acquistabile separatamente, consente di importare parti specifiche di file elettrofisiologici dai file ABF di Axon Instruments, dal formato Acquire di Bruxton Corporation e dal formato Pulse di HEKA electronik. Importazione di qualsiasi database compatibile con ODBC. Sono supportati i file di database Excel e Access. Esecuzione di query SQL sulle tabelle e importazione selettiva delle informazioni.

SigmaPlot Features

Choose from a wide range of graph types to best present your results

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.

Statistical Analysis is no longer a daunting task

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.The problem is that you don´t necessarily know that this has happened. Dynamic Curve Fitting is designed to determine if this has happened and if so what the likely best fit is.

Share high-quality graphs and data on the Web

Export your graphs as high-resolution, dynamic Web pages – not simple GIF or JPEG files. Viewers can explore data used to create graphs and zoom, pan or print images at full resolution directly from a Web Browser. Automatically generate active Web objects from your graphs or embed the objects within other Web pages.

• Simply select the Web graph to share its data with colleagues and students
• Share the data behind your graphs with colleagues and students
• Enable colleagues to print your full report from your intranet or Web site directly from their browsers – without compromising the quality of the graphs
• Create an optional password while exporting your graph to limit data access to authorized users
• Produce Web documents without knowing HTML or embed SigmaPlot Web object graphs within HTML files to create interactive electronic reports

Each worksheet can hold a list of user defined transforms that will automatically be re-run whenever the transform input data has changed.

Let’s say you would like to start by selecting a particular kind of graph but you don’t know how to set up the worksheet to achieve it. 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.

Compare and contrast trends in your data by creating multiple axes per graph, multiple graphs per page and multiple pages per worksheet. Accurately arrange multiple graphs on a page using built-in templates or your own page layouts with SigmaPlot’s WYSIWYG page layout and zoom features.

Customize every detail of your charts and graphs

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. And select anti-aliasing to display jaggy-free smooth lines that can be used in your PowerPoint® presentations.

Quickly Plot your Data from Existing Graph Templates in the Graph Style Gallery

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.

• Quickly save any graph with all graph properties as a style and add a bitmap image to the gallery
• No need to be an expert, create customized graphs in no time with the Graph Gallery
• Choose an image from the Graph Style Gallery to quickly plot your data using an existing graph template
• Save time by using a predetermined style to create a graph of the data
• Avoid re-creating complex graphs

But, remember, you don’t necessarily need to use the power of the Graph Gallery since every graph in SigmaPlot is a template. 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.

Publish your charts and graphs anywhere

Create stunning slides, display your graphs in reports or further customize your graphs in drawing packages. Save graphs for publication in a technical journal, article or paper with SigmaPlot’s wide range of graphic export options. Presenting and publishing your results has never been easier – or looked this good.

Transforms and Quick Transforms

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.

Use the Regression Wizard to fit data easily and accurately

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!

The Regression Wizard accurately fits nearly any equation – piecewise continuous, multifunctional, weighted, Boolean functions and more – up to 10 variables and 25 parameters. You can even add your own curve fit equations and add them to the Regression Wizard.

Use the Dynamic Curve Fitter to determine if your fit is valid

The Dynamic Curve Fitter performs 200 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.

Plot Nearly ANY Mathematical Function

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. It’s that simple! 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.

Maximize your Productivity with SigmaPlot’s Automation

Automate Complex Repetitive Tasks

Create macros in no time with SigmaPlot’s easy-to-use macro language. 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.
