I was analysing the google timeline chart to do some task related to my project. I took the sample code which is like this

<html>
<body>
<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 container = document.getElementById('example3.1');
  var chart = new google.visualization.Timeline(container);
  var dataTable = new google.visualization.DataTable();
  dataTable.addColumn({ type: 'string', id: 'Position' });
  dataTable.addcolumn({ type: 'string', id: 'Section'});
  dataTable.addColumn({ type: 'string', id: 'Name' });
  dataTable.addColumn({ type: 'date', id: 'Start' });
  dataTable.addColumn({ type: 'date', id: 'End' });
  dataTable.addRows([
    [ 'President','section1',          'George Washington', new Date(1789, 3, 29), new Date(1797, 2, 3)],
    [ 'President','section1',          'John Adams',        new Date(1797, 2, 3),  new Date(1801, 2, 3)],
    [ 'President',         'section1', 'Thomas Jefferson',  new Date(1801, 2, 3),  new Date(1809, 2, 3)],
    [ 'Vice President', 'section1',    'John Adams',        new Date(1789, 3, 20), new Date(1797, 2, 3)],
    [ 'Secretary of State','section1', 'Levi Lincoln',      new Date(1801, 2, 4),  new Date(1801, 4, 0)],
    [ 'Secretary of State','section1', 'James Madison',     new Date(1801, 4, 1),  new Date(1809, 2, 2)]]);

  chart.draw(dataTable);
}
</script>

<div id="example3.1" style="width: 1000px; height: 200px;"></div>
</body>
</html>

In the above example I have added this one extra column

dataTable.addcolumn({ type: 'string', id: 'Section'});

in the given example on google timeline chart.

But when I debug this example with this extra column it shows an error

Uncaught type error undefined is not a function

I don't know how to solve this problem. need speedy solution for this. I am new to google timeline chart and also in jQuery.

Took me 5 minutes to get it working, but 15 more to understand why it was not working. Its a really small mistake, but you have addcolumn instead of addColumn (c instead of C) . Correct that and it should not give an error on that line. Still will throw a Invalid data table format: must have 3 or 4 data columns , as the expected data for a TimeLine is 4 rows

Timelines | Charts, A timeline is a chart that depicts how a set of resources are used over time. the same identifier ( timeline ) used when container was declared in the first line of the bars of a timeline by adding a tooltip column into a five-column datatable. Fired when an error occurs when attempting to render the chart. First column: Enter the dates or dates and times you want to show in the chart. Second column: Enter numeric data. You can also add a category name (optional). Third and fourth column (Optional):

Google Timeline does not allow extra columns. You are only allowed 3 columns if you're omitting the bar label and 4 if it's included.

Add a Timeline to Your Website with Google Charts, Since I'm going to make use of Google API Loader to load Google We have to use the addColumn method to add each of the four columns. Create a new function called prepareDataTable () to create and initialize the DataTable. We have to use the addColumn method to add each of the four columns. Once the columns have been added, use

I see there is a possibility to add more information in the TimeLine Chart

dataTable.addColumn({ type: 'string', role: 'tooltip' });

Each Cell in this column,you program such a way, it will have a multi-columnar values.

And Use handler Event to do the JavaScript to get the appropriate information.

If you need more info, let me explain in detail.

You need a dummy column.

Replace:

dataTable.addcolumn({ type: 'string', id: 'Section'});

With:

dataTable.addColumn({ type: 'string', id: 'dummy bar label' });

To provide non-default tooltips, every row of your datatable must have all five columns (row label, bar label, tooltip, start, and end):

like someone here said: you can use role: 'tooltip' to overcome the limit and have an id on your timeline like so:

function drawChart() {
    // Define the chart to be drawn.
    var data = new google.visualization.DataTable();

    data.addColumn({ type: 'string', id: 'Date' });
    data.addColumn({ type: 'string', id: 'Name' });
    data.addColumn({ type: 'date', id: 'Start' });
    data.addColumn({ type: 'date', id: 'End' });
    data.addColumn({ type: 'number', role: 'tooltip', id: 'Id' }); //THIS IS THE EXTRA LINE - NOTE THE ROLE TYPE

    data.addRows([<?=$js;?>]);

    var options = {      
      colors: ['#0033cc', '#FFD700', '#FF7A00', '#319899', '#3FCA00', '#C20073']
    };

    // Instantiate and draw the chart.
    var chart = new google.visualization.Timeline(document.getElementById('container'));
    chart.draw(data, options);

    google.visualization.events.addListener(chart, 'select', selectHandler);

    function selectHandler(e) {
        var selection = chart.getSelection();
        if (selection.length > 0) {
            console.log(data.getValue(selection[0].row, 4)); // THIS IS HOW YOU READ IT
        }
    }

}

Google timeline chart - ShowCurrentTime, Hi all, I'm trying to use this wonderful Google charts! :) I can't put a vertical line along the chart to show the current date I think I should use the� Then choose in the menu: Insert - Chart. The Google Sheets graph is built, the chart editor is displayed. Your spreadsheet will offer you a chart type for your data at once. Usually, if you analyze indicators which vary over time, Google Sheets will most probably offer you a column chart or a line chart.

First column: Enter a label to describe the data. Labels from the first column show up on the horizontal axis. First row (Optional): In the first row of each column, enter a category name. Entries in the first row show up as labels in the legend. Other columns: For each column, enter numeric data. You can also add a category name (optional).

After loading the timeline package and defining a callback to draw the chart when the page is rendered, the drawChart() method instantiates a google.visualization.Timeline() and then fills a dataTable with one row for each president.

  • Thanks silly mistake. But Can you tell me how to pass data in add rows at a time like a array in this
  • @RanjeetSIngh what do you mean? Passing data works fine the way you are doing, its just that you can't have 5 rows of data on that chart
