Options - Documents/Graphs: Rendering

In the Options dialog box, select the Rendering tab (under Graphs) to access options to enhance graphics display.

Enable advanced graphics rendering. When this check box is cleared, Statistica will not attempt to use either Direct2D or GDI+, and instead will use the graphics engine in versions of Statistica earlier than version 10. Gradient shading, smooth (anti-aliased) lines, and transparency will not be available. When this check box is selected, Statistica will use at least GDI+, and perhaps Direct2D, depending on other option settings and if Direct2D is supported on the particular OS in use and in the hardware. See also, the Advanced Graphics Capabilities overview.

Use hardware graphics acceleration (Direct2D) when supported. When this check box is cleared, Statistica will always use GDI+, and never attempt to use Direct2D. When this check box is selected, Statistica will use Direct2D if the underlying OS and graphics hardware supports it.

On Remote Desktop, use software rendering (GDI+) when hardware support (Direct2D) is disabled or not supported. If Direct2D is not available or has been disabled, the system will use GDI+. When GDI+ is in use on Remote Desktop (used in Windows Terminal Services and Citrix environments), transparency is implemented in a faster manner that does not look as good. Instead of adjusting the color of each pixel (called alpha-blending), the system approximates this by setting areas to appropriate colors (called dithering). The effect is particularly noticeable in small areas, such as plot legends. If this is distracting, you can clear this check box, and the Remote Desktop session will not use GDI+ only when running in Remote Desktop. This means that the advanced graphics features [Gradient shading, smooth (anti-aliased) lines, and transparency] will not be available either. When this check box is selected, the GDI+ will be used even on Remote Desktop.  

Use hardware graphics acceleration (Direct2D) when creating enhanced metafiles. An enhanced metafile is used in graphics to contain a series of drawing commands that represent the graphs, rather than an image of the graph. This is useful because the drawing commands take up less memory than a static image, and also because you can play back the commands at different resolutions and produce a higher-quality image than if you rescaled the static image. Enhanced metafiles are used in several places in graphics; for instance, copy and paste into a different application, or when displaying graphs that have been inserted into reports, or the summary image inside workbooks. However, when Direct2D is enabled, instead of producing graphics commands, it produces an image internally. The result is the enhanced metafiles using Direct2D are substantially larger and do not produce as high-quality an image. Therefore, when this check box is cleared, GDI+ will be used for rendering images in enhanced metafiles. This is of particular note when running on Statistica Server because of the lack of support of GDI+, so when this check box is cleared, images produced in enhanced metafiles will not use any of the advanced graphics capabilities on Statistica Server. This is of main concern in Statistica Enterprise Server when producing scheduled reports; the graphs that go into reports use enhanced metafiles, so when this check box is cleared, the resulting graphs will not have the advanced drawing. When this check box is selected, Direct2D is used in enhanced metafiles, with the resulting increase in enhanced metafile size.

Display interactive graphics controls (the bar with sliders on the bottom of graph windows). Select this check box to display a bar containing interactive sliders at the bottom of the graph display. Use the sliders to adjust plot area transparency and marker transparency, and rotate 3D graphs. Transparency control is a powerful graphical exploratory technique that enables users to reveal trends hidden in the dense concentrations of data points (especially scatterplots and scatterplot matrices generated from extremely large data sets). The goal is to achieve the optimal density level to uncover patterns obscured by a large number of random points (white noise) that create the ink-blot effect. Also enables interactive panning and scaling options for graph axes. You can directly interact with the graph axis to pan to the right or the left by hovering the mouse above the axis labels toward the center of the axis. Interactive Panning is a powerful graphical exploratory technique that enables you to explore trends hidden in the data. Interactive Scaling is a powerful graphical exploratory technique that enables you to reveal hidden trends by stretching or compressing the desired parts of the display.

Use Version 9 marker/pattern settings (requires restarting Statistica). If you are using an earlier operating system than Windows Vista, select this check box to use Version 9 defaults, which use area pattern fill (instead of area solid fill with gradient).

Create Clipboard/Report/Metafile images at a printer resolution _ DPI.  Select this check box to specify the resolution for the graph when creating Metafiles and Enhanced Metafiles, when copying to the clipboard, placing into Statistica Reports, or when embedding Statistica Graphs objects into other applications.

Metafile representations are created for the Clipboard when Statistica Graphs are pasted as metafiles (and not as Statistica active objects) to other applications, such as MS Word. They are also used when Statistica Reports are printed or exported as RTF documents, and when you save Statistica Graphs in the Metafile (.wmf) format in order to edit them as vector images in other programs.

In most typical applications, leave this option selected, and the resolution (which you can specify in the DPI edit field) at the default 600 DPI (i.e., set at low resolution, the default setting) in order to create directly printable representations of Statistica Graphs in other programs. Note that, depending on the resolution of your display, these images may not look as "clean" on the screen as when this option is cleared or when higher resolution metafiles are generated. In that case, the metafiles will be generated using high resolution rendering that, on most high-quality printing devices, may create output with too thin lines (e.g., with a single device pixel lines on a 1200 DPI printer).

Note that this option does not affect the quality of graphs saved/printed as Statistica Graphs files/objects, where the precise translation of the requested line thickness into printed or displayable resolution is not limited by compatibility concerns resulting from using the metafile (.wmf) representation.

Do not use bitmap copy operations when printing. When this check box is selected, graph items will be drawn in a slightly different way when printed. If you are printing and objects come out black or misaligned, try selecting this check box.
