Wp Custom Field Chart

Description

This plugin collect data attached to post/article via custom field and make
chart of it.
This plugin use Chart.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)",
