6.1.8 Zooming & Panning in a plot If you want to investigate details in a plot, you can zoom in on the area of interest. Permanent zoom Using the property editor is one way of doing this by increasing minimumvalues and/or reducing maximum-values on the horizontal and/or the vertical axis of the plot. Although very accurate, this approach require that you enter four new boundary limits for the plot, and switching back to the full view requires you to change all four limit-values once more. Consequently this approach is only recommended, if you wish to zoom in permanently on a specific area of your plot. Zoom out x 2 To get a better overview of a plot, you can quickly zoom out: right-click in the plot window and select Zoom out x 2. Temporary zoom If you wish to temporarily zoom in on a specific area, and do not require the limit-values to be so accurately defined, a different approach can be used: Simply press the Ctrl- or the Shift-key on your keyboard, and hold it down while selecting a rectangular area in your plot using the mouse. The area is selected by pressing the left mouse button in a corner of the intended zoomarea, and then drag the mouse to the opposite corner. When you release the left-hand mouse button in the opposite corner, the system will zoom in on the area selected. Zooming out You can zoom in repeatedly going into still finer details of your plot, and zooming out again can either return you to the full view or to the previous level of magnification: Right-click inside the magnified plot, and select either Zoom Out or Zoom Restore from the context menu that appears. Alternatively you can use the corresponding keyboard shortcuts Alt-Z or Ctrl-Alt-Z to respectively zoom out one level, or return to the full view. Panning Whether or not you have zoomed in on a plot, you can pan up, down, left or right, using the arrow-keys on the keyboard. Pressing the up or down-arrow will shift the plot up or down in steps of 20% of the current plot height, and similarly pressing the left or right-arrow keys will shift the plot left or right in steps of 20% of the current plot width. Restoring a plot If you loose track of your plot having used several zooms and pans, you can always return to the settings in the property editor by running the plot object: Select the plot and press the run-key ( ) on the toolbar, or use the shortcut key F5. Right-clicking the plot object in the project explorer and selecting Run from the resulting context menu has the same effect. Reading values The Advanced Graphics Add-On can also help you reading numerical values in a plot: Left-click the mouse while pointing somewhere within the plot area. The coordinates of the current cursor position will then be read out in the status bar in the lower right-hand corner of the screen. Please be aware that within the Windows operating system, the position of the mouse cursor is measured in screen-pixels. This limits the resolution achievable when reading values in a plot, and to improve the accuracy of the reading, you may wish to maximise the plot to fill the entire workspace. 6-30 BSA Flow Software: Options and Add-ons
6.1.9 Exporting plots Copying a plot to the Clipboard Printing a plot All of the previous text in section 0 of this document relates to plots on the screen, but they remain an integral part of the BSA Flow Software. This section describes how you can export the plots, so they can be used in a report or presentation to document your results. Prints will be scaled to fit the paper selected, while exporting plots to a file or to the clipboard, will yield exact copies of what you see on the screen. Using the Clipboard is the traditional way of sharing information between different applications on the Windows platform: 1. Select the plot that you wish to copy by clicking either the plot window in the workspace, or the plot-icon in the project explorer. 2. Copy the selected plot to the clipboard in one of the following ways: • Click the Copy-button ( ) in the toolbar, or… • Select Copy from the Edit menu, or… • Use the keyboard shortcut Ctrl-C, or… • Right-click the plot-window in the workspace, or the plot-icon in the project explorer, and select Copy from the context menu that appears. Either way the selected plot will be copied to the clipboard in two formats: Bitmap and Enhanced Metafile. Other Windows applications can now import the plot from the clipboard in either of the formats supplied. Printing a plot can also be considered an export, since a plot printed on paper is no longer an integral part of the BSA Flow Software. 1. Select the plot that you wish to print by clicking either the plot window in the workspace, or the plot-icon in the project explorer. 2. Send the selected plot to the printer in one of the following ways: • Click the Print-button ( ) in the toolbar, or… • Select Print from the File menu, or… • Use the keyboard shortcut Ctrl-P, or… • Right-click the plot-window in the workspace, or the plot-icon in the project explorer, and select Print from the context menu that appears. Provided a printer is included in your Windows installation, you will get a print dialog similar to the one shown in Figure 6-34, where you may be able to select the number of copies to print, which printer to use and which settings to use on the selected printer.
