jquery - flot piechart from PHP -

-

i having strange issue creating piechart in flot data php.

it seems drawing incorrectly, , can't figure out why.

my php code (for testing) is:

echo json_encode( '[{ label: "series1",  data: 10}, { label: "series2",  data: 3}, { label: "series3",  data: 9}, { label: "series4",  data: 7}, { label: "series5",  data: 8}, { label: "series6",  data: 17}]' );

my js file is:

$.ajax({ type:'get', datatype:"json", url:'../phpfile.php', success: function(data) {     console.log(data);     $.plot($("#piechart"),data,{         series: {             pie: {                 show: true             }         }     }); } });

the consol log shows: 

[{ label: "series1",  data: 10}, { label: "series2",  data: 3}, { label: "series3",  data: 9}, { label: "series4",  data: 7}, { label: "series5",  data: 8}, { label: "series6",  data: 17}]

which thought correct format flot...

but graphs this: piechart

does have ideas?

i believe json invalid, @ moment, you're trying parse json string, json string (if mean!) currently, when echo out php end echo'ed json_encode(), i'm provided with:

"[{ label: \"series1\", data: 10},\r\n{ label: \"series2\"]"

furthermore, use php arrays encode json, below:

<?php      $arr = array(          array(             "label" => "series1",             "data" => 10         ),         array(             "label" => "series2",             "data" => 3         ),         array(             "label" => "series3",             "data" => 9         ),         array(             "label" => "series4",             "data" => 7         ),         array(             "label" => "series5",             "data" => 8         ),         array(             "label" => "series7",             "data" => 17         )     );      echo json_encode( $arr ); ?>

php json_encode() does accept mixed variable types, it's popularly used php arrays.

with above, i'm able construct pie chart successfully:

finished chart
