Plan 3.0: 2D Plot

  • For simple experiments with only one device, the Slave list will come pre-loaded with the current slave.
  • The Variable list allows you to select what you want to plot. Up to 6 variables can be plotted at once.
  • X-Axis:
    • By default it's in Automatic mode, 200 points.
    • You can change it to manual and plot 1 to 1000 points.
  • Y-axis:
    • By default it's in Automatic mode. It scales based on the data plotted.
    • A dropdown menu allows you to pick between percentages and units. This is used to always make the vertical span bigger than the maximum and minimum data points.
    • Tip: the ±5 ticks option is great to analyze sensor noise.
  • The m & b boxes allow you to transform values based on the y=mx+b equation. This can be used to bring different sensors on the same order of magnitude.
  • The statistics conveniently display key parameters for each signal
  • Option Bar Buttons:
    • Freeze! / Release: Freeze will make the display static. We use that when a specific event happens and we want time to analyze the situation. Clicking Release will start refreshing the display again.
    • Clear Plot clears the display
    • Default sets all variables back to Unused
    • IMU loads the 6 IMU channels
    • Sequential populates variables 2 to 6 based on variable 1.
    • Screenshot takes a screenshot of the current screen, and saves it in [Saved-Screenshot] folder.
    • Cursor Mode enables two cursors. They can be used to take measurements on a waveform.
  • The dashed line separating the plotting area from the rest can be used to resize the plot.
  • Freeze mode tips:
    • You can draw a box with your mouse (click, drag & release) to zoom in on data
    • Double-clicking brings it back to the default scale

OpenGL Accelerated Series

By default, the 2D Plot uses OpenGL Accelerated Series to overlay the waveform traces. Some machine configurations may have trouble supporting this due to driver issues or OpenGL versioning mismatches.

To disable OpenGL Accelerated Graphics:

1. In the Menu toolbar, navigate to Help -> OpenGL Settings
2. Click Disable OpenGL ASG

This setting will apply to all future 2D Plot windows opened in this instance of PlanGUI.

To revert back to OpenGL Accelerated Graphics:

1. In the Menu toolbar, navigate to Help -> OpenGL Settings
2. Click Enable OpenGL ASG

In some uses with multiple 2D Plot windows open, you may notice overlapping data traces being drawn even when the 2D Plot window is in the background. Disabling OpenGL Accelerated Series will prevent this from happening by plotting the traces directly in the 2D Plot window.
