I noticed the example which mentions it can be linked to a database <https://developers.google.com/chart/interactive/docs/php_example> requires the data to be formatted in .json format.
I would like to keep my data in the format which is shown in the Line Charts <https://developers.google.com/chart/interactive/docs/gallery/linechart> section. Is it possible to stay away from having to format my sql query to json format? Formatting my SQL query into this so Google Charts has turned into a bit of a nightmare. { "cols": [ {"id":"","label":"Topping","pattern":"","type":"string"}, {"id": "","label":"Slices","pattern":"","type":"number"} ], "rows": [ {"c":[{"v": "Mushrooms","f":null},{"v":3,"f":null}]}, {"c":[{"v":"Onions","f":null},{"v" :1,"f":null}]}, {"c":[{"v":"Olives","f":null},{"v":1,"f":null}]}, {"c":[{"v" :"Zucchini","f":null},{"v":1,"f":null}]}, {"c":[{"v":"Pepperoni","f":null},{ "v":2,"f":null}]} ] } my getData2.php $query = sqlsrv_query($conn,'SELECT elapsedTime, vfor FROM voltage1'); $table = array(); $table['cols'] = array( /* define your DataTable columns here * each column gets its own array * syntax of the arrays is: * label => column label * type => data type of column (string, number, date, datetime, boolean) */ //array('label' => 'elapsedTime), array('id' => 'Elapsed Time', 'type' => 'string'), array('id' => 'Forward Voltage', 'type' => 'string'), // etc... ); $rows = array(); while($r = sqlsrv_fetch_array($query)) { $temp = array(); // each column needs to have data inserted via the $temp array $temp[] = array('v' => $r['elapsedTime']); $temp[] = array('v' => $r['vfor']); // etc... // insert the temp array into $rows $rows[] = array('c' => $temp); } // populate the table with rows of data $table['rows'] = $rows; // encode the table as JSON $jsonTable = json_encode($table); // set up header; first two prevent IE from caching queries // header('Cache-Control: no-cache, must-revalidate'); // header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // header('Content-type: application/json'); // return the JSON data echo $jsonTable; My getData2.php output {"cols":[{"id":"Elapsed Time","type":"string"},{"id":"Forward Voltage","type":"string"}],"rows":[{"c":[{"v":1},{"v":"7.362491054"}]},{"c":[{"v":2},{"v":"13.69094212"}]},{"c":[{"v":3},{"v":"18.09654105"}]},{"c":[{"v":4},{"v":"19.96053457"}]},{"c":[{"v":5},{"v":"19.02113033"}]},{"c":[{"v":6},{"v":"15.41026486"}]},{"c":[{"v":7},{"v":"9.635073482"}]},{"c":[{"v":8},{"v":"2.506664671"}]},{"c":[{"v":9},{"v":"-4.973797743"}]},{"c":[{"v":10},{"v":"-11.75570505"}]},{"c":[{"v":11},{"v":"-16.88655851"}]},{"c":[{"v":12},{"v":"-19.64574501"}]},{"c":[{"v":13},{"v":"-19.64574501"}]},{"c":[{"v":14},{"v":"-16.88655851"}]},{"c":[{"v":15},{"v":"-11.75570505"}]},{"c":[{"v":16},{"v":"-4.973797743"}]},{"c":[{"v":17},{"v":"2.506664671"}]},{"c":[{"v":18},{"v":"9.635073482"}]},{"c":[{"v":19},{"v":"15.41026486"}]},{"c":[{"v":20},{"v":"19.02113033"}]},{"c":[{"v":21},{"v":"19.96053457"}]},{"c":[{"v":22},{"v":"18.09654105"}]},{"c":[{"v":23},{"v":"13.69094212"}]},{"c":[{"v":24},{"v":"7.362491054"}]},{"c":[{"v":25},{"v":"7.35089E-15"}]},{"c":[{"v":26},{"v":"-7.362491054"}]},{"c":[{"v":27},{"v":"-13.69094212"}]},{"c":[{"v":28},{"v":"-18.09654105"}]},{"c":[{"v":29},{"v":"-19.96053457"}]},{"c":[{"v":30},{"v":"-19.02113033"}]},{"c":[{"v":31},{"v":"-15.41026486"}]},{"c":[{"v":32},{"v":"-9.635073482"}]},{"c":[{"v":33},{"v":"-2.506664671"}]},{"c":[{"v":34},{"v":"4.973797743"}]},{"c":[{"v":35},{"v":"11.75570505"}]},{"c":[{"v":36},{"v":"16.88655851"}]},{"c":[{"v":37},{"v":"19.64574501"}]},{"c":[{"v":38},{"v":"19.64574501"}]},{"c":[{"v":39},{"v":"16.88655851"}]},{"c":[{"v":40},{"v":"11.75570505"}]},{"c":[{"v":41},{"v":"4.973797743"}]},{"c":[{"v":42},{"v":"-2.506664671"}]},{"c":[{"v":43},{"v":"-9.635073482"}]},{"c":[{"v":44},{"v":"-15.41026486"}]},{"c":[{"v":45},{"v":"-19.02113033"}]},{"c":[{"v":46},{"v":"-19.96053457"}]},{"c":[{"v":47},{"v":"-18.09654105"}]},{"c":[{"v":48},{"v":"-13.69094212"}]},{"c":[{"v":49},{"v":"-7.362491054"}]},{"c":[{"v":50},{"v":"-1.47018E-14"}]}]}?> -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
