@Sushanth, currently there's no simple option for it - what happens is that the input is converted to a number, and as numbers are printed into a string, JavaScript only adds the number of decimals needed.

Hi Torstein,

Firstly, thanks for the awesome plugin. In the jsfiddle demo while exporting floating point values like 140.0, the decimal part is getting truncated is there a work around to retain the decimal part. Thanks in advance

How to reploace the server side code with C# wcf?

i want to export chart as a whole to csv what should i do for that

This is nice but it doesn't seem to output the x-axis values if the chart is an xy-scatter or a time-series line chart.

Updated the demo to work with Highcharts 3.0.

This is a very attractive feature, AFAICS the example is not (no longer?) working though.

Thank you @Mathew Weaver
Worked for me. Had to make few changes based on my chart. (instead of series.data[j].x, I needed series.data[j].category)

I would not say it is impossible to make a nice save dialog. You could in fact fake the first part of the process rendering the format of the data into a dialog box, wherein there is a file name input, and a download/save button. Upon submitting the file then the URI would be implemented with the parameters from the save dialog.

As Josh said, getting the viewable chart data is fairly easy. Here is a code snippet:

var csv = "";

for (var i = 0; i < chart.series.length; i++) {
if (chart.series[i].name == 'Navigator') continue;
var series = chart.series[i];
for (var j = 0; j < series.data.length; j++) {
if (series.data[j] != undefined && series.data[j].x >= series.xAxis.min && series.data[j].x <= series.xAxis.max) {
csv = csv + series.name + ',' + Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', series.data[j].x) + ',' + series.data[j].y + '\r\n';
}
}
}

I am looking to do the same thing that you describe. Did you ever get any further with this? Would you mind sharing a code snippet that gets the viewable chart data into a data URI?

In case anybody's interested, it's easy to transform the viewable chart data into a Data URI, but it's impossible to make a nice save as dialog.
