The Graph2D plug-in creates 2D and 3D graphs, lines and bars from imported files.

This page contains the following topics and procedures:

Graph2D Properties

• use LOD: Renders higher or lower detail for the object. This setting depends on the camera/object distance, and renders with marginal quality casualties if this toggle is switched on. LOD stands for Level of Detail. 

• Channel: Affects the Channel File to search for. The file holds the vertex and other data to define the whole graph.

• Use: Loads the file through a Channel File or remote access.

• Max (%): Sets the rage for rendering. For example, if the range is set to 50% the graph is cut 50% in width.

• 3D: Enables 3D rendering of the graph, and the Show Back option.

  • Show Back: Enables the object to show the back in case the object is rotated.

• Type: Following types are available: Graph, Line and Bars. Take a change if you want another visual depiction. Graph enables the Reduction and Minimum Points settings. Line enables the Constant Width, Line Width (%), Reduction (%) and Minimum Points settings. Bars enables the Bars Width (%) and Bar Animation settings.

  • Reduction (%): Reduces points by the Douglas-Peucker algorithm. The Douglas-Peucker algorithm is an algorithm for reducing the number of points in a curve that is approximated by a series of points.

  • Minimum Points: Changes the number of points for rendering the graph.

  • Constant Width: Sets a constant width.

  • Line Width (%): Changes the width of the line.

  • Reduction (%): Reduces points by the Douglas-Peucker algorithm. The Douglas-Peucker algorithm is an algorithm for reducing the number of points in a curve that is approximated by a series of points.

  • Minimum Points: Changes the number of points for rendering the graph.

  • Bar Width (%): Changes the width of all bars.

  • Bar Animation: Renders each bar separately when One by One is selected. Renders all bars at the same time when All together is selected.

• Use Colors: Sets the color for positive and negative values. This setting is only available for graphs and bars (not line).

• Show Frame: Shows the frame around the graph. Useful for orientation.

• Aspect Ratio: Stretches the graph evenly in x-direction.

• Refresh Data File: Reloads the Channel File, which holds the data value for the x- and y-points.

To Create a Channel File for a Graph2D

1. Create a text file (for example, CHANNEL2), with no file extension.

2. Add this data: 5 0 0 10 20 20 0 30 20 40 0.

   • The first number (5) holds the number of points available in the file.

   • The other definitions are the X and Y points -> (0/0), (10/20), (20/0) etc.

3. Create this directory: <viz data folder>\plug-in\graph2D. and place the channel file in it.

To Create a 2D Graph

1. Create a new Container.

2. Add the Graph2D plug-in.

3. Add a Material and/or a Texture.

4. Set the Channel parameter to the Channel file (for example: 2 for CHANNEL2).

5. Click Refresh data file if the Channel file contents have been modified.
