This dialog allows you to adjust the appearance and scaling of all axes in a 3D/spectrogram window. You can open this dialog by using "Edit/Axes settings" option from the menu.



Z-Axis Range


•The Max and Min fields define the range of the Z-axis (typically amplitude). You can enter values manually or adjust them using the up/down arrows next to each field.

•The Auto button automatically sets the Min and Max fields to the actual minimum and maximum values currently present in the graphic.


Display Options


•Instant preview: When selected, the window is redrawn immediately as you modify Min or Max values. For complex 3D graphics, you may wish to disable this option to improve performance.

•Fixed min/max (no auto-scale): When enabled, SIGVIEW will retain the defined Z-axis range and prevent it from being recalculated automatically as the data changes.

•Show axes: Displays the coordinate axes and their labels. Uncheck this option to show only the data without axes, which can improve rendering speed.


Axis Scaling


•Logarithmic Y-Axis: Displays Y-axis data (for example, frequency in a Time-FFT) using a logarithmic scale.

•Logarithmic Z-Axis: Displays Z-axis data (typically amplitude) on a logarithmic scale.

•Both logarithmic options can also be toggled from the 3D window’s context menu.


Axis Labels


•The X label, Y label, and Z label fields define the text shown beside each axis when Show axes is selected (for example, sec, Hz, or Amplitude).
