How it works:
I use jQuery AJAX to call an application process called GET_EMPLOYEES_RELATIONSHIP.
The response is in JSON. I use jQuery to handle the JSON object.
You need to store your chart data inside a "google.visualization.DataTable()" object.
I use the same data table to feed the Table Chart and the Org. Chart.
I created 2 examples.
1) Single Tree View
Your can see a working example of the employees relationship Organizational Chart demo (1).
This is how I define a data table cell:
for (i = 0; i < emp_count; i++) {
l_data_table.setCell(i, 0, data[i].emp_ename);
l_data_table.setCell(i, 1, data[i].mgr_ename);
}
2) Multiple Trees View
Your can see a working example of the employees relationship Organizational Chart demo (2).
This is how I define a data table cell:
for (i = 0; i < emp_count; i++) {
l_data_table.setCell(i, 0, data[i].emp_empno, data[i].emp_ename);
l_data_table.setCell(i, 1, data[i].mgr_empno, data[i].mgr_ename);
}
Enjoy! :)
I'm not done yet with the Google Visualization API... there's still plenty of charts to try out.
