js for chart drawing ChartJs
Data are collected by looking for specific custom field attached to your
post/page. You can change aggregation method, intervall…
See usage
Usage
Edit your post/page in text mode and put some Javascript and a WordPress tag
Minimum
<script> var mydata = { datasets: [{}]}; </script> [custom_field_chart fields="humidity" js_data="mydata"]
For each field you need to put empty {} into datasets.
For two fields:
<script> var mydata = {datasets: [{},{}]} </script> [custom_field_chart fields="humidity,temperature" js_data="mydata"]
But it’s pretty useless to put more than one field without different colors 🙂
More
<script> var mydata = { datasets: [ { label: "Humidity", fillColor: "rgba(255,73,0,1)", strokeColor: "rgba(255,73,0,1)", pointColor: "rgba(255,73,0,1)", pointStrokeColor: "#fff", pointHighlightFill: "#fff", pointHighlightStroke: "rgba(220,220,220,1)", }, { label: "Temperature", fillColor: "rgba(255,73,0,1)", strokeColor: "rgba(255,73,0,1)", pointColor: "rgba(255,73,0,1)", pointStrokeColor: "#fff", pointHighlightFill: "#fff", pointHighlightStroke: "rgba(220,220,220,1)", }, ] };
2, barStrokeWidth: 2, barValueSpacing: 2, barDatasetSpacing: 0, };
// Optional... onAnimationComplete = function(){ alert('Hello'); } }); // End optional </script>
