Controls

Default Export Directory edit box - This control allows you to specify the default directory location for exports to be performed. Users can still override this location in the Export Window.
-
Browse button - This button will display the Open File dialog to allow you to pick a directory location on your hard drive. This location is placed in the Default Export Directory edit box.
-
Output Variables As group - This selection determines how variables are written into text files. In the data files, each variable has both a text label such as "Male" and an underlying value such as "1". This selection determines whether the numeric value is written, the label in quotes, or just the label. Continuing the previous example, either 1, "Male", or Male would be written into the text file. Sometimes quotes are needed around labels if the label contains a space or other odd characters.
-
Line Delimiter group - This selection determines what is written at the end of each line in the text file. Different environments use different end of line characters. In Windows and Dos, then end of line indicator is carriage return followed by line feed. In a Unix environment, the end of line indicator is just a line feed.
-
Field Delimiter group - This selection determines what is written between fields in a text file to distinguish them from each other. You can select either a tab, a comma, or a semi-colon. Tab is a good choice if you intend to use the exported file within Excel.
-
Override Graph Resolution check box - This option determines whether you would like to override the graph resolution saved to file. The default is to save the graph at the same resolution as it is displayed on screen. With this option on, you can save the file in a larger format (which is good if you intend to use the image in print). When this option is on, the Width and Height edit boxes will become accessible.
-
Width and Height edit boxes - These entries allow you to set the width and height in pixels of export graphs. These are only available if you override the graph resolution. The minimum side is 1 pixel and the maximum is 10,000. Keep in mind that a size of 1 pixel is useless, and a size of 10,000 may not be possible based on the memory of your system.
-
Image Format group - This selection determines the type of image file to write when exporting graphs. The most compact and versatile format is PNG, but JPG is another commonly used image format.
