Scales Page (Display Properties Dialog Box)

Click the Properties button on the Data View tab or right-click a display and select Properties from the shortcut menu to display the Display Properties dialog box. Select the Scales tab to display this page.

Use this page to format scales and grids on graph and chart displays.

This page includes the following components:

• Scale—Specifies the scale you want to configure.
• Name—Specifies the name of the scale.
• Show scale label—Specifies whether to display the name of the scale, Name, on the graph or chart display.
• Show scale—Specifies whether to display the scale on the graph or chart display.
• Log—Specifies whether to map the scale logarithmically. Remove the checkmark from this checkbox to map the scale linearly.
• Timestamp Type—Specifies the type of timestamp to associate with the plot. You can select from the following options:
  • Ignore—Specifies to not associate any timestamp with the plot. LabVIEW SignalExpress displays all signals starting at time 0, regardless of when you begin acquiring the signal.
  • Absolute—Specifies to associate the absolute time with the plot. LabVIEW SignalExpress displays all signals starting at the absolute time at which you begin acquiring the signal.
  • Relative To: signal—Specifies to plot signal starting at time 0 and to plot the other signal(s) relative to that signal. For example, if you begin acquiring the other signal(s) 10 seconds after you begin acquiring signal, LabVIEW SignalExpress displays signal starting at time 0 and the other signal(s) starting at time 10.
• X-Axis Signal—Specifes the signal to use for the x-axis. This option appears only if the display you are configuring is an xy graph display.
• Autoscale—Specifies whether LabVIEW SignalExpress sets the scale automatically based on the data in the graph. Remove the checkmark from this checkbox if you want to specify a range for the scale.
  • Minimum—Specifies the minimum value of the scale. Remove the checkmark from the Autoscale checkbox to enable this component.
  • Maximum—Specifies the maximum value of the scale. Remove the checkmark from the Autoscale checkbox to enable this component.
• Scaling Factors—Specify the value at the origin of the plot and adjust the scale of the plot. For example, to plot a time-domain waveform in milliseconds starting at a reference time, set Offset to the reference time and Multiplier to 0.001, because LabVIEW SignalExpress displays time in seconds by default.
  • Offset—Specifies the initial value for scaling data. If you change Offset, the scale no longer uses 0 as the origin of the plot.
  • Multiplier—Specifies the multiplier, or interval, for scaling data.
• Scale Style and Colors—Specifies the appearance of the scale. Click the button to display a pull-down menu of scale style options. This section also contains the following components for specifying the color of the scale:
  • Major tick—Specifies the color of the major tick mark.
  • Minor tick—Specifies the color of the minor tick mark.
  • Marker text—Specifies the color of the scale marker text.
• Grid Style and Colors—Specifies the appearance of the grid. Click the button to display a pull-down menu of grid style options. This section also contains the following components for specifying the color of the grid:
  • Major grid—Specifies the color of the major grid line.
  • Minor grid—Specifies the color of the minor grid line.
  • BG Color—Specifies the background color of the graph.
