Hello, I am trying to generate the json files that I could use to make a google material bar chart.
I want to show a comparison on three different sets of data like the following screen shot shows (which is generated using a regular array). <https://lh3.googleusercontent.com/-L5OO9MYgafQ/VwyVxMWKuJI/AAAAAAAAAD4/6d9b_NLGamw4mVsgiHUyF-XIm2Ees1LvwCLcB/s1600/Screen%2BShot%2B2016-04-12%2Bat%2B1.24.52%2BAM.png> I tried to write a similar json file as the array does for the previous graph, but it ended up like <https://lh3.googleusercontent.com/-6i9h98H0KVU/VwyWRTBtsCI/AAAAAAAAAD8/d_MliIKutRUXIjlrckxbjFyf-_wgBWRfACLcB/s1600/Screen%2BShot%2B2016-04-12%2Bat%2B1.31.12%2BAM.png> Here is my json file: { "cols":[ {"id":"type","label":"Sensor Type","type":"string"}, {"id":"hum","label":"Humidity","type":"number"}, {"id":"temp","label":"Temperature","type":"number"}, {"id":"light","label":"Light","type":"number"} ], "rows":[ {"c":[{"v":"Average"},{"v":26.371523433721},{"v":26.671470588235},{"v":9.3347814338235}]}, {"c":[{"v":"Maximum"},{"v":26.829065672},{"v":27.25},{"v":27.46580625}]}, {"c":[{"v":"Minimum"},{"v":26.004174242},{"v":26.25},{"v":0}]} ] } And the javascript code I use this file to generate the graph: var responseText = JSON.parse(event.target.responseText); // Create our data table out of JSON data loaded from server. var data = new google.visualization.DataTable(responseText); setTimeout(getData, 5000); var options = { chart: { title: "Summary", subtitle: 'Average, Minimum and Maximum Data of the zone' }, bars: 'horizontal', // Required for Material Bar Charts. series: { 0: { axis: 'Average' }, 1: { axis: 'Maximum' }, 2: { axis: 'Minimum' } }, axes: { x: { humidity: {side: 'top', label: 'Humidity (%)'}, // Bottom x-axis. temperature: {side: 'top', label: 'Temperature (Celsius)'}, // Top x-axis. light: {side: 'top', label: 'Light (Lux)'} } } }; var chart = new google.charts.Bar(document.getElementById('chart_div')); chart.draw(data, options); The graph is showing the average/min/max value of the humidity, temperature and light. Is this the issue with the material graph? Or is it because I did the json in wrong format? Thank you very much for your help.
