highchart activity gauge chart using json data from a file - json

Question

I am new to using highcharts.js. I want to create an activity gauge chart using data from a json file or url. I have understood how they draw the chart but failed to understand the data format used in json to display the chart.
Here is my code
var options = {
chart: {
type: 'solidgauge',
marginTop: 50
},
title: {
text: 'Activity',
style: {
fontSize: '24px'
}
},
tooltip: {
borderWidth: 0,
backgroundColor: 'none',
shadow: false,
style: {
fontSize: '16px'
},
pointFormat: '{series.name}<br><span style="font-size:2em; color: {point.color}; font-weight: bold">{point.y}%</span>',
positioner: function (labelWidth, labelHeight) {
return {
x: 200 - labelWidth / 2,
y: 180
};
}
},
pane: {
startAngle: 0,
endAngle: 360,
background: [{ // Track for Move
outerRadius: '112%',
innerRadius: '88%',
backgroundColor: Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0.3).get(),
borderWidth: 0
}, { // Track for Exercise
outerRadius: '87%',
innerRadius: '63%',
backgroundColor: Highcharts.Color(Highcharts.getOptions().colors[1]).setOpacity(0.3).get(),
borderWidth: 0
}, { // Track for Stand
outerRadius: '62%',
innerRadius: '38%',
backgroundColor: Highcharts.Color(Highcharts.getOptions().colors[2]).setOpacity(0.3).get(),
borderWidth: 0
}]
},
yAxis: {
min: 0,
max: 100,
lineWidth: 0,
tickPositions: []
},
plotOptions: {
solidgauge: {
borderWidth: '34px',
dataLabels: {
enabled: false
},
linecap: 'round',
stickyTracking: false
}
},
series: []
};
var gauge1;
$.getJSON('bryan.json', function(json){
console.log(json)
options.chart.renderTo = 'container';
options.series.data = json
gauge1 = new Highcharts.Chart(options);
});
/**
* In the chart load callback, add icons on top of the circular shapes
*/
function callback()
{
// Move icon
this.renderer.path(['M', -8, 0, 'L', 8, 0, 'M', 0, -8, 'L', 8, 0, 0, 8])
.attr({
'stroke': '#ffffff',
'stroke-linecap': 'round',
'stroke-linejoin': 'round',
'stroke-width': 2,
'zIndex': 10
})
.translate(190, 26)
.add(this.series[2].group);
// Exercise icon
this.renderer.path(['M', -8, 0, 'L', 8, 0, 'M', 0, -8, 'L', 8, 0, 0, 8, 'M', 8, -8, 'L', 16, 0, 8, 8])
.attr({
'stroke': '#ffffff',
'stroke-linecap': 'round',
'stroke-linejoin': 'round',
'stroke-width': 2,
'zIndex': 10
})
.translate(190, 61)
.add(this.series[2].group);
// Stand icon
this.renderer.path(['M', 0, 8, 'L', 0, -8, 'M', -8, 0, 'L', 0, -8, 8, 0])
.attr({
'stroke': '#ffffff',
'stroke-linecap': 'round',
'stroke-linejoin': 'round',
'stroke-width': 2,
'zIndex': 10
})
.translate(190, 96)
.add(this.series[2].group);
}

</div>
And here is my json data which i thout might be rendered but it didnot.
data.json

First of all, instead of options.series.data = json, you need to create the first series and then populate its data array with your data. Also, set in each point different radius and innerRadius properties. Take a look at the example below.
