I too was just now looking for a way to disable tooltips for a single column inside my google line chart. The above answer isn't far off but I guess it isn't completely clear.
There is no way to "disable" tooltips for a single column, however you can disable interactivity for a single column which as far as I can tell results in the same wanted behavior. To do so, simply use the series inside the chart options as such:
series :{
0:{
enableInteractivity: false,
tooltip: 'none'}
}
Or a longer example:
var options = {
tooltip: {isHtml: true},
legend: 'none',
chartArea: {
width: 500,
},
lineWidth: 2,
series: {
0: { }, // Output
1: { enableInteractivity: false, tooltip: 'none', lineDashStyle: [2, 2] },
2: { enableInteractivity: false, tooltip: 'none' },
},
colors: ['#6f9654', '#1c91c0', '#7F3F98'],
};
var chart = new google.visualization.LineChart(document.getElementById('myChart'));
chart.draw(dataTable, options);
I found the answer here: https://groups.google.com/forum/#!topic/google-visualization-api/ZADPolRZtxM
And this works for me.. I have a line chart with 3 columns (3 lines in the chart) and I was able to "disable" tooltips on 2 of them using this technique.
