Adding Multiple Scales to Graphs or Charts

Use multiple scales on a graph or chart to accommodate plots that do not share a common x-scale or y-scale. Only certain types of graphs and charts support multiple scales.

LabVIEW supports multiple x-scales or y-scales for visualizations as follows:

Supported Scales Supported Visualizations
Multiple x-scales, multiple y-scales
  • Waveform graphs
  • XY graphs
  • Intensity graphs
  • Digital waveform graphs
Multiple y-scales only
  • Mixed signal graphs
  • All types of charts

To add a scale to a waveform graph or chart, complete the following steps.

  1. Hover your cursor over a scale label, right-click, and select Duplicate Scale from the shortcut menu.
    LabVIEW adds a copy of the scale to the same side of the plot area.
  2. To move the new scale to the opposite side of the display, right-click the scale and select Swap Sides.
  3. Associate a plot to the new scale with either of the following methods:
    • Right-click a plot glyph in the plot legend and select the scale to associate from the options within X Scale or Y Scale.
    • Right-click the waveform graph and select Properties » Plots. Then, use the Y-scale and X-scale pull-down menus to associate a plot with the correct scale.
    If the plot legend is not visible, right-click the graph or chart and select Visible Items » Plot Legend from the shortcut menu.
  4. To change the range of the new scale, select the end values of the scale and enter new values.
    Tip If you manually change the range of the scale in this way, disable autoscaling.
