java - dygraph error - this.rawData_ is undefined -

-

i using dygraph generate graph using csv file , getting below error @ firebug.

typeerror: this.rawdata_ undefined

i investigated issue , found csv not being loaded entirely , label formatting being done. hence have used drawcallback.

graph_obj_2 = new dygraph(             document.getelementbyid("graphdiv2"),              "http://localhost:8080/report_2.csv", // path csv file             {             //options             legend: 'always',             animatedzooms: true,             drawcallback: function(g, is_initial) {                             if (!is_initial) {                                     return;}                             },             axes: {                 x: {                 valueformatter: function(x) {                 var label;                 switch (x){                     case 1:                      label = '0';                     break;                               case 2:                      label = '1';                     break;                               case 3:                      label = '2';                     break;                               case 4:                      label = '3';                     break;                 }return label;                 },                 axislabelformatter: function(x) {                 var label;                 switch (x){                     case 1:                      label = '0';                     break;                               case 2:                      label = '1';                     break;                               case 3:                      label = '2';                     break;                               case 4:                      label = '3';                     break;                 }return label;                 },             }             }         });
