[Solved]-Server side chart .svg export with Highcharts and PhantomJS, error loading data from .csv file-Highcharts

the $.get function is out of place here. jquery $.get loads data from the server using a get request. instead you need a plain file read.

an example how you could do this.

// read the csv file
var data = fs.read('test.csv');

var svg = page.evaluate(function(opt, data) {
    ...
    var lines = data.split('\n');
    // iterate over the lines and add categories or series
    $.each(lines, function(lineno, line) {
       ...
    });
},evalarg, data);
