Display all tooltips in chartjs

I'm using http://www.chartjs.org/ to create a simple line graph.

Now I want to show all tooltips. I do not want default on Hover behaviour. I am certain that at any moment I will not have more than 10-12 points on graph. So I want the tooltips to be always open.

If this is not possible with ChartJS, I'm open for opting for other library.

Solution

I don't know if this is possible with chartjs (a quick search did not reveal anything) but I think what you want is possible using highcharts. Here you can use the datalabels option:

plotOptions: {
            line: {
                dataLabels: {
                    enabled: true
                },

Here is a demo. Does that help?

EDIT:

Another possibility for free could be jqPlot. For a demo have look here! There is a pointLabels plugin which places labels on the plot at the data point locations. Should do the trick. :)

var plot1 = $.jqplot('chart1', [line1], {
      title: 'Point Labels', 
      seriesDefaults: { 
        showMarker:false,
        pointLabels: { show:true } 
      }
  });

Cheers and good luck.
