I recently add HighChart to my project and I want create chart by it.I wrote this code to create chart for temprature in monthes in some cities:
function CreateChart() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
ype: 'line',
//type: 'column',
shadow: true,
zoomType: 'x',
style: {
fontFamily: 'Tahoma'
}
},
title: {
text: 'Nima Report',
x: -20 //center
},
labels: {
items: {
style: {
fontFamily: 'Tahoma'
}
},
style: {
fontFamily: 'Tahoma'
}
},
subtitle: {
text: 'Source: --',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
labels: {
rotation: -45,
align: 'right',
formatter: function () {
return '<span style="font-size: 18px;">' + this.value + '</span>';
}
}
},
yAxis: {
title: {
text: 'Temp'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}],
labels: {
align: 'right',
formatter: function () {
return '<span style="font-size: 18px;font-weight: bold">' + this.value + '</span>';
}
}
},
tooltip: {
crosshairs: [true, true],
enabled: true,
style: {
fontFamily: "Tahoma",
textAlign: "right"
},
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
this.x + ': ' + this.y + '°C';
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0,
labelFormatter: function () { return '<span style="font-family: Tahoma">' + this.name + '</span>'; }
},
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]

Reset to default 6add min to y-axis:
yAxis: {
title: {
text: 'Temp'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}],
labels: {
align: 'right',
formatter: function () {
return '<span style="font-size: 18px;font-weight: bold">' + this.value + '</span>';
}
},
min:0,
},
