[jacksonc1]

I am using highcharts server side export.I am trying to render an image of graph..I am using json.I have null values(for missing points) in series data.But json is not accepting null unless we give it as 'null'.Due to this the graph image is not getting displayed properly.Can you please help me how to pass data for missing values to json in highcharts serverside export one2team.
For example the data series i have given is

"name:"

• "'ACTUAL FORECAST'" + ","
• "fillOpacity:" + "'0.1'" + "," + "data:" + "[" +
  "100000," + "350000," + "441000," + " 'null'," + " 'null'," + " 'null'," + " 'null'," + " 'null'," + " 'null',"
• " 'null' " +
  Thank you,
