3D graphics: basic operations and zooming
  


Rotation
If you want to get a good look on 3D graphic from all sides, use arrow keys on your keyboard to rotate 3D graphic in all directions. This is possible only if you are not in ruler mode (see below).

Switching Waterfall / Mesh view
You can switch from waterfall (lines only) to mesh (solid rectangles) view by choosing 3D Tools/Mesh option from menu or by pressing  graphic  button in toolbar. You can also use F2 key as a shortcut to switch between views.

Ruler

By pressing TAB key or  graphic  button in toolbar you can switch to ruler mode. Ruler will appear on the graphic and you will be able to move it with keyboard arrow keys. The rulers X,Y position and f(X,Y) for the current ruler position will appear in status bar at the bottom of the screen.

To move the ruler 10x faster through the graphics, press SHIFT key together with arrow keys.

Zooming in/out

Zooming-in part of the graphic:

In spectrogram view, simply select the part of the graphics with mouse (rounding box), and then choose Edit/Zoom in menu or toolbar option. If the ruler is turned on, zoom-in option will always zoom-in to an area around the current ruler position.

For 3D-graphics in a spectrogram view, you can perform a fast zoom-in our zoom-out by using your mouse wheel.

Edit/Zoom out option and graphic  button from toolbar will restore the zoom positions before the last zoom in operation.

Zoom-in graphical content of the window:

By pressing graphic  and graphic  buttons in toolbar you zoom in/out only graphical content of a window. This zooming will affect the displaying only the data displayed will remain the same.


Palettes: In a 3D graphics mesh mode, the color of the rectangles is defined by a current palette. You can define it for each window separately from its context menu or from the main menu. The available palettes are:

·     Hot (red/black),
·     Blue (blue/black),
·     Gray (white/black),
·     Copper (yellow/black),
·     HSV (all colors),
·     White (inverted gray palette)
·     Jet
·     Rainbow
·     Winter
·     Autumn
·     Spring
·     Summer
·     Cool

Inverting colors: If the 3D graphics is in a Mesh mode, you can invert it colors by choosing Invert colors menu option from the context or main menu. By mot palettes, it will provide the graphics with the light colors for the values around 0, making the graphics much more printer-friendly.

Z-axis adjusting
When 3D graphic is recalculated and redrawn because its parent signal has changed, min & max values are not automatically recalculated to avoid speed loses. This can cause 3D graphic to go out from visible part of coordinate system, or can corrupt the color layout. If that happens, you can select 3D Tools/Adjust Z-axis option from menu and min & max values for Z axis will recalculate. This will solve all described problems.

Exporting 3D graphics values in file: By using options File/ASCII/CSV files/Export 3D-graphics, you can export all values from the visible part of the 3D graphics in a one file. There are 3 options: export in a file with X,Y,Z triples in 3 columns (tab delimited), as a matrix where first row contains X values, first column Y values and the rest of the file are Z values in a tab delimited table and finally inverted variant of the second matrix format (with switched rows and columns). All of these file types can be loaded by, for example, MS Excel for further analysis.

Copying 3D graphics values to the clipboard: By using menu option Edit/Copy data to clipboard, all values from the visible part of 3D graphics will be copied to clipboard. The data format will be the same as when exporting data in ASCII/CSV: matrix where first row contains X values, first column Y values and the rest of the file are Z values in a tab delimited table.
