json - Passing data to rickshaw with php -


i'm having trouble integrating data rickshaw graph.

i'm getting values database via php, converting output json array.

json string:

[{"x":"1431002979","y":"1079.547"},{"x":"1431007200","y":"1079.5468"},{"x":"1431010800","y":"1079.5469"},{"x":"1431014400","y":"1079.5469"},{"x":"1431018000","y":"1079.5472"},{"x":"1431021600","y":"1079.5473"},{"x":"1431025200","y":"1079.5475"},{"x":"1431028800","y":"1079.5478"},{"x":"1431032400","y":"1079.5479"}]

i parse json this:

var data=json.parse('<?php  echo json_encode($data); ?>');

if try load data folling error

uncaught exception: x , y properties of points should numbers instead of undefined , undefined

so figured there s.th wrong data type , did this

    for(var i=0;i<data.length;i++) {     data[i]=[parseint(data[i]['x']),parsefloat(data[i]['y'])]; }

i still same error though.

this code graph:

var graph = new rickshaw.graph( {         element: document.queryselector("#chart"),         width: 580,         height: 250,         series: [ {             data: data,             color: 'rgba(255, 0, 0, 0.4)'         } ] } );  graph.render();

greetings david

try only

<?php  echo json_encode($data,json_numeric_check)); ?>

var graph = new rickshaw.graph( {          element: document.queryselector("#chart"),          width: 580,          height: 250,          series: [ {                            color: 'rgba(255, 0, 0, 0.4)',              data:  <?php  echo json_encode($data,json_numeric_check)); ?>          } ]  } );    graph.render();
