Here's my Position tables:
My position table
cant really seem to figure out whats the problem.
-Ive got a button and a dropdown, when an item is selected from the dropdown and button is selected an orgchart must be displayed. The chart displays but the problems are:
-orgchart splitting into three charts
-And it keeps showing some Id's
-here's my code:
google.load("visualization", "1", { packages: ["orgchart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
$("#btnGetOrganogram").on('click', function (e) {
debugger
$ddlDepOrgano = $('[id$="ddlDepOrgano"]').val();
if ($ddlDepOrgano != "") {
var jsonData = $.ajax({
type: "POST",
url: '/services/eleaveService.asmx/GetChartData',
data: "{'depid':'" + $ddlDepOrgano + "'}",
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: OnSuccess_getOrgData,
error: OnErrorCall_getOrgData
});
function OnSuccess_getOrgData(repo) {
var data = new google.visualization.DataTable(jsonData);
data.addColumn('string', 'Name');
data.addColumn('string', 'Manager');
data.addColumn('string', 'ToolTip');
var response = repo.d;
for (var i = 0; i < response.length; i++) {
var row = new Array();
var Pos_Name = response[i].Pos_Name;
var Pos_Level = response[i].Pos_Level;
var Emp_Name = response[i].Emp_Name;
var Pos_ID = response[i].Pos_ID;
var Emp_ID = response[i].Emp_ID;
data.addRows([[{
v: Emp_ID,
f: Pos_Name
}, Pos_Level, Emp_Name]]);
}
var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));
chart.draw(data,{ allowHtml: true });
}
function OnErrorCall_getOrgData() {
console.log("something went wrong ");
}
} else {
bootbox.alert("Invalid Department Name please try again.");
}
e.preventDefault();
});
}

Answer 1

according to the data format, Column 1 should be the ID of the manager, which is used to build the tree...
Column 1 - [optional] The ID of the parent node. This should be the unformatted value from column 0 of another row. Leave unspecified for a root node.
looking at the data table image posted, this should be in column --> Mngr_ID
as such, recommend the following changes when loading the data...
for (var i = 0; i < response.length; i++) {
var row = new Array();
var Pos_Name = response[i].Pos_Name;
var Emp_Name = response[i].Emp_Name;
var Emp_ID = response[i].Emp_ID;
var Mngr_ID = response[i].Mngr_ID;
data.addRow([
{
v: Emp_ID,
f: Pos_Name
},
Mngr_ID,
Emp_Name
]);
}
