There are two ways in which Objective Chart can interact with Objective Grid. The first is shown in the FirstGraph sample which demonstrates how the ComDoc system using the SECComDoc class allows one document in an application to communicate with and send data to another document in the same application. The ComDoc system is discussed in Chapter 20, “Communication Document System.”

The second method for Objective Chart to work together with Objective Grid is for the chart to behave as part of the grid's main display by working inside a grid-cell.
