Graphics

UNISTAT features one of the best graphics subsystems that can be found in any statistical package. To view samples of graphics output and some of the available user interface options, click 'Procedures' on the left.

On-screen editing: UNISTAT supports full on-screen object editing of graphs. All text, legends, and the graph itself can be drag-dropped and resized and new text and shape objects added. The final configuration can be saved as a graphics template file for future use. All graphics attributes including fonts, colours, titles, legends, axes, frame, tick marks, line styles, line thickness can be controlled from a series of dialogs available under the graphics menu.

Rich Text support: It is possible to mix different fonts and sub/superscripts in any text object. You can copy and paste formatted text between UNISTAT text objects and MS Word or other Windows applications.

Axes: UNISTAT can display axis titles and X-axis tick labels at 0º, 90º, 270º rotations or in top-to-bottom orientation, format the scale numbers and enter mathematical expressions for the minimum, maximum, minor and major tick values (e.g. 2*Pi()). Linear, log base 10, log base e, probit and logit scales are supported.

Symbols: It is possible to select from the ten standard symbol types for each data series, or to load special fonts (symbol, wingdings, etc.) to display as symbols. Symbols enclosing an area (such as circles, squares, triangles) can be filled with solid colours or coloured patterns and their size adjusted.

Error bars: Vertical/horizontal, symmetric/asymmetric error bars can be drawn for each data point on 2D and 3D scatter plots, bar, area and ribbon charts.

Interactive graphics: Clicking on and highlighting points on a number of graphs (in 2D and 3D scatter diagrams, 3D spin, polar, normal probability and regression plots) displays information on these selected points. Simultaneously, the row of the spreadsheet containing the point is also highlighted. In this way, it is easy to determine which points are outliers in the data set. In regression plots, if the key is pressed while a point is highlighted, then this point will be omitted and the graph redrawn with a new regression equation.

3D options: The Spin Plot procedure permits the drawing of an X-Y-Z scatter diagram of three variables and rotation of the plot in all directions in real time. All 3D graphics procedures allow the rotation and selection of the view point, as well as selecting one of parallel, one-point, or three-point perspectives. It is possible to draw contour maps on top and / or bottom planes for 3D graphs displaying a surface (i.e. X-Y-Z graphs with surface fitting, plot of 3D functions, 3D grid plot), or alternatively display a 2D contour map with extended annotation.

Exporting: The current image can be sent to Word, Excel or to web browser simply by clicking on the Word or Excel buttons on the toolbar. Graphs can be exported to other applications via the clipboard or as a file in the form of bitmap images or Windows metafiles.

Chart Gallery: The same data set can be plotted in many different graph styles instantly, without going through the variable selection process for a second time.

Categorical Plots: An unlimited number of data and factor variables can be selected for categorical plots.

Means Plots: X-Y Plots, Polar Plot, Bar Chart, Area Chart and Ribbon Chart procedures allow automatic plotting of means of the data series selected with optional standard error bars.

Curve Fitting: It is possible to fit 2D curves, 3D surfaces, display contour maps and fit distribution functions on histograms.
