Hello,
Trying to get visualizations.PieChart working, but its drawing a blank
white box with a title even though there is data. Here is my code.
<div id="globalramdonut" class="globalramdonut"></div>
google.charts.load('current',
{'packages':['corechart','gauge','line','controls','geochart']});
google.charts.setOnLoadCallback(drawAllCharts);
var ramdonutdata;
function setramdonutdata(){
var query = "SELECT Location, SUM(RAMCapacityGB) AS 'RAM Capacity GB' FROM
clusterstat WHERE Date = (SELECT MAX(Date) FROM clusterstat) GROUP BY
Location ASC";
//encode the query so we can submit it via URL.
var urlencoded = encodeURI(sql2json+query);
// get the data returned from 'urlencoded'
var jsonData = $.ajax({
url: urlencoded,
dataType: "json",
async: false
}).responseText;
console.log(urlencoded);
// assign a google DataTable object
ramdonutdata = new google.visualization.DataTable(jsonData);
}
function drawRamDonut(){
setramdonutdata();
var options = {
title: 'RAM Capacity by Location',
pieHole: 0.4,
sliceVisibilityThreshold: 0
};
var chart = new
google.visualization.PieChart(document.getElementById('globalramdonut'));
chart.draw(ramdonutdata,options);
}
function drawAllCharts(){
drawRamDonut();
}
Here is the data returned from my PHP script....
{"cols":[{"label":"Location","type":"string"},{"label":"RAM Capacity
GB","type":"number"}],"rows":[{"c":[{"v":"Amsterdam"},{"v":"12286.34"}]},{"c":[{"v":"Argentina"},{"v":"383.97"}]},{"c":[{"v":"Belgium"},{"v":"8189.33"}]},{"c":[{"v":"Brazil"},{"v":"2047.59"}]},{"c":[{"v":"California"},{"v":"14523.22"}]},{"c":[{"v":"Guadalajara"},{"v":"767.90"}]},{"c":[{"v":"Hong
Kong"},{"v":"4351.54"}]},{"c":[{"v":"Massachusetts"},{"v":"3647.56"}]},{"c":[{"v":"Ontario"},{"v":"383.97"}]},{"c":[{"v":"Oregon"},{"v":"174896.81"}]},{"c":[{"v":"Shanghai"},{"v":"1279.90"}]},{"c":[{"v":"South
Korea"},{"v":"383.19"}]},{"c":[{"v":"Tennessee"},{"v":"3327.52"}]},{"c":[{"v":"Texas"},{"v":"1535.64"}]},{"c":[{"v":"Tokyo"},{"v":"719.64"}]},{"c":[{"v":"Virginia"},{"v":"44882.59"}]}]}
Thanks for reading.
