Getting Started with Graphs

  • Create a new graph. Once you have created at least one table in CODAP, click the graph button on the top toolbar.
  • Note: Graphs start as a configuration of randomly scattered data points.
  • Drag attributes (variables) from the column headers of the tables onto the horizontal (x) and vertical (y) axes to view a graph of those variables.
  • Create additional graphs to explore different relationships.

How to edit graphs

Initially, data points are randomly distributed in the graph. Drag the attributes from the table to the axes to organize the data. Drop a column header onto the center of a graph to color the data points by the attribute.
  • Drag axes to change the graph's scale and origin.
  • Drop an attribute onto the center of a graph to color the display according to the attribute.
  • Change the graph axes. Drag new attributes to the axes. Or click on the axis title to display a menu of attributes.
  • Click on the ruler menu item: to show or hide connecting lines between points, add a moveable line to your graph, or plot any of a wide variety of functions on top of the graph's data.
