3-D Surface Plot Options

The 3-D Surface display options dialog box can be activated by selecting the <Options><Plot Options><3-D Surface> menu or by clicking on the options dialog icon button in the plot toolbar.

Frequency Span:  If "Full Span" is selected, the display will show the entire available frequency span.  When "Custom Span" is selected, the frequency values can be directly entered.

Display Update Interval:  Normally a new line is added to the plot whenever a new FFT is computed.  You may elect to only update the plot every N seconds.  This is most useful in the Real-Time mode.  In this way, long term frequency -vs- time studies can be conducted.

Plot Top/Range/Bottom:  The Plot Top and Range values determine the amplitude values.  Plot Top is the value at the upper edge of the plot.  The lower edge of the plot is always equal to the Top value minus the Range value.  When linear scaling is selected for the amplitude axis, the Plot Range value is set to zero and cannot be changed.   When Log Magnitude scaling is selected for the amplitude axis, the Plot Range value changes to become the Plot Bottom value.

Colors:  The color of each plot feature can be changed.  The "Default" button will restore the initial colors settings.    The Multicolor Gradient option displays the data with amplitudes shown in a color gradient; a color bar to the right of the plot shows the amplitude/color relationship and the cursor measurements will also show amplitude values.   The "Custom Color" option lets you choose the minimum and maximum colors.  

Show Toolbar: Show or hide the plot toolbar.  A small + or - button below the toolbar also controls this feature.

Show RPM instead of Time: This will replace the time axis values with RPM values from the tachometer channel.  The cursor measurements will also display RPM values.  

Copy these settings to other channels: Allows you copy the plot options to other channels you select.

Notes:
  • Any changes to the display option will cause the 3-D Surface plot to automatically rebuild itself with the new settings (press the Escape key to cancel the rebuild). This behavior will not occur when the analyzer is in the Real-Time mode because the underlying time series data is no longer available.
