Hi I have the following code to draw timeline chart. It is giving me Invalid column index undefined. Should be an integer in the range [0-3] error. Can anyone help?
<script type="text/javascript" src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization', 'version':'1','packages':['timeline']}]}"></script> <script type="text/javascript"> google.setOnLoadCallback(drawChart); function drawChart() { var dataTable = new google.visualization.DataTable(); dataTable.addColumn({ type: 'number', id: 'no' }); dataTable.addColumn({ type: 'string', id: 'Project' }); dataTable.addColumn({ type: 'date', id: 'Start Dt' }); dataTable.addColumn({ type: 'date', id: 'End Dt' }); dataTable.addRows([ [ 0, 'proj1', new Date(2013, 10, 29), new Date(2014, 5, 3) ], [ 1, 'proj2', new Date(2014, 2, 3), new Date(2014, 6, 3) ], [ 2, 'proj3', new Date(2014, 1, 1), new Date(2014, 12, 31) ], [ 3, 'proj4', new Date(2013, 10, 1), new Date(2014, 4, 1) ], [ 5, 'Mt5', new Date(2013, 9, 3), new Date(2014, 5, 3) ]]); var chart = new google.visualization.Timeline(document.getElementById('projects')); var options = { timeline: { showRowLabels: false } }; chart.draw(dataTable, options); } </script> -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
