Graph view

The Graph view enables you to visualize the 3D (world) and 2D (image) coordinates of selected point(s), for a selected sensor. It can help you to investigate point stability and/or jitter for selected point(s).

To display the Graph view:

1.    Ensure that the view in which you want to view the graph is active and that you have selected the point(s) for which to display a graph.

2.    At the top right of the camera views, click Graph.

A Graph view for Sensor 0 of the currently selected point(s) is displayed, with the x-axis displaying the frame number, and the y-axis displaying the coordinate value, which for 3D coordinates is in mm, and for 2D coordinates is in pixels.

Use the following mouse/menu actions to work in the Graph view:

Required action	Menu/mouse combination
Display a graph for a sensor other than sensor 0	Right-click on the view, and on the on the context menu, point to Sensor, and then click the required sensor name.
Zoom in to the graph range for the data	Right-click on the view and then click Fit to Data.
Pan in the Graph view	SHIFT+left+right mouse buttons (or middle mouse button) and drag
Zoom in the Graph view	SHIFT+right mouse button and drag

For each selected point, the Graph view displays either:

❙       Three lines (if the point is not visible in the selected sensor), representing the 3D point x, y, and z coordinates plotted against frame number; or

❙       Five lines (if the point is visible in the current sensor), representing 3D point x, y, and z coordinates, and additionally, 2D image x and y coordinates, plotted against frame number.

The line color indicates which coordinate is being plotted:

❙       Red = x

❙       Green = y

❙       Blue = z

The following example Graph view shows the 3D and 2D coordinate data for a single point, for sensor 0.
