SigmaPlot Helps You Quickly Create Exact Graphs
With the new Graph Properties user interface you can
select the property category in the tree on the left and then change
properties on the right. 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.
The “select left and change right” procedure makes
editing your graphs quick and easy. SigmaPlot takes you beyond simple
spreadsheets to help you show off your work clearly and precisely. With
SigmaPlot, you can produce highquality graphs without spending hours in
front of a computer. SigmaPlot offers seamless Microsoft Office^{®} integration, so you can easily access data from Microsoft Excel^{®} spreadsheets and present your results in Microsoft PowerPoint^{®} presentations.
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. For example you might want to add Notebook Save,
Close All, Refresh Graph Page and Modify Plot.

Below are some of the many new features in SigmaPlot Version 14:
New Graph Features
 Arrows with solid arrowheads
 Added a right mouse menu command for pasting copied graph primitives (arrow, box, etc.) on the page

 Improved User Interface for the Quick Transforms dialog
New Miscellaneous Features
 Unicode is now supported
 Automatic Updating is available within SigmaPlot to get the latest updates to features
 User settings are now preserved for new versions of SigmaPlot
 Added new ribbon layouts for different types of workflows
 The Export button is also on the Main button
 New Macro Method for Exporting any Graph Page Selection

Graph Features
Arrows with Solid Arrowheads
The solid arrowhead is much more aesthetic than an arrowhead consisting of intersecting lines.
Right Mouse Graph Primitive Paste
A graph primitive object can now be both copied and pasted from the
right click menu. This saves editing steps. These objects include the
graph, boxes, circles, arrows, lines and text.
Toggle between Zoom Levels
One of the goals of this release is to make some procedures simpler.
This is one of them. You frequently zoom in to make fine modifications
but then you want to zoom out to see the overall effect. A toggle Ctrl+3
has been added. It will toggle between your current zoom level and 100%
enabling you to easily make the changes and then see the result.
Data sampling dropdown now shows the maximum number of rows in the column
Data sampling in Graph Properties allows you to select the “from, to,
by” rows for your graph. It also shows a sampling of the data rows but
not every row and, in particular, not necessarily the last row. The “to”
label now shows the numerical length of the column. This is a small
feature but may help the user by catching a misselected column and also
help you select the “by” number of rows.
Turn Off Left Mouse Selection Minitoolbars
Some users only want right mouse selection minitoolbars. The Main
Button, Options, Page has a new checkbox: “Show mini toolbars on
selection”. If you turn this off, mini toolbars will not appear when you
select (left mouse) an object on the Page, but will still appear if you
right click.
New Antialiasing Button
Use of antialiasing will smooth lines on your graph. This presently
exists but was somewhat hidden under a right click on the page. This new
button on the ribbon makes the feature obvious.
Improved User Interface for the Color Schemes Dialog
An unnecessary mouse click was removed. The color scheme dialog is
displayed immediately. This feature and the next are examples of
removing unnecessary mouse clicks.
“Each Curve” Option is Automatically Turned on when Performing a Linear Regression on One Plot
It is enabled in the Plot Regression dialog. This saves one step for a commonly used procedure.
Additional Plot Regression Statistics
More statistics have been added to the results in the Plot Regression
dialog that is used for polynomial fitting to graph data. The statistics
include the model performance measures R2, Adjusted R2, Standard Error
of the Estimate and the Akaike Information Criterion. These are in
addition to the standard errors for parameters and confidence intervals
for the parameters. A control has also been added to change the number
of results decimal places.
Improved Access to Result Graphs Following Statistical Analysis
Result graphs following a statistical analysis can now be obtained by
right clicking either a statistical report or the page outside another
result graph as shown below.
Scatter Matrix Graph Dimension is Increased to 40 Variables
The scatter matrix result graphs have increased support to a maximum of 40 variables:
Graph Properties Can Now Be Obtained by Right Clicking a Graph or Plot
The Graph Properties panel can be obtained from the Home tab or by
double clicking a graph or plot on a graph. To make this even more
visible, Graph Properties can now be obtained by right clicking on a
graph or plot.
Renamed Linear Regression command in the Graph Analysis group of the Analysis tab to Plot Regression
This is to emphasize that this regression is obtained from a plot on a
graph and not from the worksheet. The name change is also made to the
dialog and tool tip text.
Text and Special Symbols Options are Now Shown Directly on the Symbols Dialog
A Symbol Font button has been added to the Symbols dialog. This makes it
easier to change the font and visualize directly what it will look like
on the graph. A Special Symbols button has been added which contains
120 addition symbols.
The Graph Additions Group Name Has Been Changed to Manage Plots
For clarity, the name of the Graph Additions panel on the Graph Page tab
has been changed to Manage Plots since this is what these functions do.
Multiple Result Graph Types May Now be Simultaneously Selected from the Create Result Graph Dialog
Multiple Result Graph types may be selected using the mouse left click.
This enables the user to perform in one step what before required
multiple dialog openings. The keyboard behavior of selecting one graph
using the arrow keys has not changed.
The Default Appearance of Result Graphs Improved
The default Result Graph appearance has been improved by modifying graph
attributes that include axis line thickness, tick mark thickness, plot
line thickness and color schemes for lines, line styles, symbol size and
symbol edge thickness. The various line thicknesses and color schemes
have been set to visually pleasing values.
Gray Scale TIFF Option Added
A Gray Scale option has been added to TIFF RGB export (compressed or not).
Added a Page Templates Button on the Graph Page Ribbon Tab
Page templates are more easily accessible from the ribbon with a Templates button in the Format group of the Graph Page tab.
Worksheet Features
Sorting Data in the Worksheet Now Supports Multiple Key Columns
Use the Sort feature from the Worksheet tab Edit group to sort using multiple key columns.
Coefficient of Variation and 90% Confidence Interval added to Column Statistics
Use the Worksheet tab and View group to select View Column Statistics
(or press F6). The image below shows the addition of % CV and 90%
Confidence.
Formatted Text Can Now be Used in Statistical Analyses
Three formatted “a”s and three formatted “b”s are entered into a
worksheet to identify groups for a statistical test. The small square in
the upper right corner of the worksheet indicates that that text is
formatted. Then, in the example below, the formatted text in the graph
is increased in size. SigmaPlot now recognizes formatted text for
statistical tests as it did in the past for plain text. A graph using
these two groups and the ttest report are shown below:
Custom Column Statistics Items and Order May Now Be Specified
Specific Column Statistics items may now be selected and their order
specified. Do this from the Main button, Options, Worksheet tab,
Statistics when a Column Statistics worksheet is the current window. The
two list box interface is shown below:
Analysis Features
OneWay Frequency Tables Method
The oneway frequency tables method is new. It is applicable to multiple
worksheet columns. It computes the number of times independent variable
values occur.
Enhancement of the Unpaired Ttest
The unpaired (aka 2independent samples) ttest has been enhanced to
provide the option to test the equality of the population means of the
two groups without assuming equal variances (Welch’s ttest).
Improved Ttest Reports
The option of selecting Pvalues from either a twotailed or a
onetailed ttest has been added. This simplifies the appearance of the
report giving the most useful results. Text has been added to explain
the possible use of Welch’s test: “Use the results of Welch’s test,
where equal variances are not assumed, if the equality of the population
variances of the two groups is in doubt.”
More Nonlinear Regression Application Examples Added to Nonlin.jnb
Nonlinear regression examples are found in Help, SigmaPlot Samples and
Nonlinear Regression. The file is located in the Samples subfolder of
the user’s profile folder.
Improvements to the Transforms Examples Xfms.jnb
Several new transforms have been added with example worksheets and
graphs. In SigmaPlot 13, this file contained 25 transforms. Some of
these have been removed because a corresponding macro gives better
results, but several more were added, with descriptions, worksheets and
graphs so that this file now contains 55 transforms. Also, this file is
now copied to the user profile folder during installation and is
accessible from the Help menu in SigmaPlot (Help, SigmaPlot Samples and
Transforms).
Improvements to Some Automatic Parameter Estimation Functions in the Transform Language
APE functions are used by SigmaPlot’s nonlinear regression feature. They
determine good starting values for the fitting function’s parameters.
The ape functions for polynomial and rational polynomial functions have
been improved to avoid illconditioned or singular solution for the
parameter estimates. Also, for power users, the ape function and the
polynomial function used together in a userdefined transform provide a
quick way of doing Polynomial Regression.
Number of Groups for Dummy Variables has been Extended From 100 to 1000
This is for users who want to use dummy variables for coding categorical
variables for specific procedures in SigmaPlot’s statistics, like
logarithmic regression, or covariates for Cox regression and ANCOVA. The
advanced user can also use them to extend SigmaPlot’s multifactor
ANOVA by again converting the categorical variables to dummy variables
and using multilinear regression (GLM). As an example of the number of
dummy variables required, a 5x5x5 3Way ANOVA requires 124 dummy
variables to describe it as a regression model, which is done internally
in SigmaPlot. The dummy variable interface has been used with
multilinear regression to verify examples of SigmaPlot’s ANOVA results,
but this could not have been done for the ANOVA design above in the
previous version of SigmaPlot since the old limit was 100 dummy
variables.
Error Message and Partial Save Nonlinear Regression Improvements
Increased the types of nonlinear regression error messages reported when
using the Function Edit dialog to create fit equations. The ability to
save partially complete equations so that the user can return to them
later for completion has been added.
Improved the Histogram and Polynomial Transform Language
Functions and the Exponential Operator to Handle the nth Root of
Negative Numbers
The Transform Language function histogram was modified to add an
optional third argument whose default value is zero. If the value of
this argument is zero, the function behaves as before, assigning data to
a bucket whose value equals the bucket’s right edge. If the value of
the argument is not zero, then data is assigned to a bucket if its value
equals its left edge instead. The behavior with a nonzero argument is
more conventional. The Transform Language function polynomial was
modified to replace its method for evaluation to use the Horner
algorithm which is faster and more accurate. Also increased the maximum
degree of the polynomial you can evaluate to 1000.
Added the ability to compute nth roots of negative numbers when n is an odd integer
Before, this resulted in missing values. So, for example, (8)^(1/3) or
(8)**(1/3) should now yield 2. Also, if you were to graph the equation
y=x^(1/3) for negative values of x before this change, you would get
nothing.
UserDefined Transform and Regression Dialogs are Now Resizable
The UserDefined transform dialog for defining transforms and the
Function Edit dialog for defining regression models can now be resized
and have their new sizes saved between sessions of SigmaPlot. This makes
them more convenient to use by preventing frequent scrolling to make
editing changes.
Improved User Interface for the Quick Transforms Dialog
Two Quick Transforms windows have been combined making the combined
window much easier to handle. Additional transform functions were also
added as buttons: median, nth, avg, choose, rgbcolor, runavg, fft,
invfft, normdist, norminv, tdist, tinv, fdist and finv. Also, the
constants “π“ and “e” were added.
Miscellaneous Features
Using Unicode Characters in the Worksheet on the Graph Page and in Reports
Here is an example of Unicode Russian characters in the graph:
User Settings are now Preserved for New Versions of SigmaPlot
Every change that the user makes in SigmaPlot is saved as a setting
(saved in the spwUserSettings.ini file). From SigmaPlot 14 on, a new
version of SigmaPlot will use the previous file of settings so that the
user will “see” SigmaPlot exactly as it was before.
New Ribbon Layouts for Different Types of Workflows
There are now four different ribbon layouts for users that have specific uses:
 Default
 Compact
 Graphing
 Analysis
A good example of using the new configurations to speed up the
workflow is in the Compact configuration. Here, the Worksheet tab has
both worksheet and analysis commands and the Graph tab has both graph
creating and editing commands. This shows the power of the new
configurations as it saves a lot of switching back and forth between
tabs.
Worksheet Tab
Graph Tab
Export Button is now also on the Main Button
The user can use the Main button and not repeatedly return to the Home tab to export.
New Macro Method for Exporting any Graph Page Selection
A new macro method has been added for the Auto Graph Item data type
called ExportGraph and is used to export any selection on a graph page
to a file. The method has seven arguments. From left to right, the
arguments are filename, image file format and dpi, color resolution in
bits, selection flag, height and width. This is used for both writing
macros and in macro recording when running the Graph Export Dialog.
Added a Save All command to the Main Button
You can now save all open notebooks with one click.
Two New Macros Using Indexed Data for Graphing
Two new macros have been added to Macro Data Sets.jnb and SigmaPlot
Macro Library.jnb. These macros (Box Plot, Using Indexed Data, Error Bar
Plots Using Indexed Data) show how indexed data is used in graphing,
expanding what SigmaStat does in result graphs.
Sample Data Sets Available from Help
Help now has a SigmaPlot Samples item from which sample data sets can be
opened. Notebooks for Graphs, Statistical Tests, Macro Data Sets,
Transforms and Nonlinear Regression are available.
New Macro Automation Method to Determine a Worksheet Column Length
A new automation method has been added on the automation DataTable
object given by long ColumnLength (long col). This method finds the
length of a column defined from the first row to the last nonempty row.
A return value of zero shows that the column is empty.
Data Can Now be Extracted from a Result Graph More Easily
Data for a Result Graph is contained internally and not in a worksheet.
You can now extract the data from a Result Graph by selecting the Data
button in the Navigate group of the Home tab. A Result Graph must be in
focus. The tooltip for the Data button will say “View Graph Data.” A new
section will be created with a worksheet containing the data. This
allows extracting the data for a Result Graph and placing it into a
worksheet.
