In the major branch of the properties dialog, an isometric 3D view similar to the FFT view can be configured for the chart.

In this mode, the successive views of a chart are displayed on a Z-axis, with the newest results closest to the axes origin, in order to create a waterfall effect. Images and regions are always shown in the rearmost plane, texts appear in the foreground. The number of Z levels is optionally configurable. However, note that using an isometric perspective demands more resources than using the 2D representation. Especially when a larger number of previous points are displayed in the X-Y pair.

Zoom functions are limited to the foreground layer.

The axis layout settings are overridden in the 3D mode. Axes are always displayed at the side of the chart not overlapping with the perspective flow direction.

The perspective itself is configurable by dragging the back plane center point. The back plane center point is marked with a small gray cross, and the cursor will change when you move over it. When dragging the presentation, the spectra disappear and the perspective will be adjusted.

By right clicking in the view, the context menu opens. Choose Perspective and then Front to force the 3D view into front perspective for example. This precise view would not be possible with simply dragging the center point.

The other settings have the following effect:

• Default: Positioning of the 3D view in default perspective

• Side: Side view

• Locked: It is not possible to change the perspective by dragging the center point.

The advance is either time-controlled in the given update interval or triggered by a digital signal.
