    <p>You can't replace the text if you want to use the annotation functionality (as the text is what is generated by the annotations). You could use an overlapping data series to show only certain points. Here's an example that shows an overlapping series (I removed the annotations for simplicity, but you can still use them if you want to):</p> <pre><code>function drawVisualization() { var data = new google.visualization.DataTable(); data.addColumn('number', 'Overs'); data.addColumn('number', 'Run-rate'); data.addColumn('boolean', 'Wicket falls'); data.addRows([ [1, 6, false], [2, 6, false], [10, 2, true], [20, 3.2, false], [21, 3, true], [30, 4, true], [40, 5, false], [50, 6, false] ]); // create a DataView that duplicates points on the "Run Rate" series where "Wicket falls" is true var view = new google.visualization.DataView(data); view.setColumns([0, 1, { type: 'number', label: data.getColumnLabel(2), calc: function (dt, row) { // return the value in column 1 when column 2 is true return (dt.getValue(row, 2)) ? dt.getValue(row, 1) : null; } }]); var options = { title: 'Run Rate', pointSize:0, hAxis: { gridlines: { color: 'transparent' } }, series: { 0: { // put any options pertaining to series 0 ("Run-rate") here }, 1: { // put any options pertaining to series 1 ("Wicket Falls") here pointSize: 6, lineWidth: 0 } } }; new google.visualization.LineChart(document.getElementById('chart_div')). // use the view instead of the DataTable to draw the chart draw(view, options); } google.load('visualization', '1', {packages:['corechart'], callback: drawVisualization}); </code></pre> <p>See working example here: <a href="http://jsfiddle.net/asgallant/saTWj/" rel="nofollow">http://jsfiddle.net/asgallant/saTWj/</a></p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
