Highcharts generation on server using Phantomjs in Asp .net

I am using Highcharts. I need to send highcharts as attachment in email. I can generate highcharts on server using PhantomJS.
http://www.highcharts.com/docs/export-module/render-charts-serverside[^]
I changed the config parameters in highcharts-convert.js. I am able to generate chart using following on command prompt:

phantomjs highcharts-convert.js -infile options.js -outfile chart.png

& the contents of options.js file is

{infile:{xAxis:{categories:["Jan","Feb","Mar"]},
series:[{data:[29.9,71.5,106.4]}]},
constr:"Chart",
outfile:"//chart.png"}

The problem is that the generated chart is blank with Title as "Chart Title". I tried with changing the extension of js to json, that didn't work too.
I found a solution on stackoverflow

But, still it's not working.

Any help would be highly appreciated.
