Milestone Trendanalysis with Highcharts - highcharts

Question

Is it possible to make the following chart with Highcharts library?
It's a simple line chart but with inverted triangle shaped grid. Is there any predefined type or a way to customize the grid shape? Any pointers which will guide me to a proper direction would help. Thank you!

Answer 1

Another method of how to create this type of chart:
Demo
Highcharts.chart('container', {
chart: {
width: 500,
},
xAxis: {
opposite: true,
title: {
text: 'Report Date'
},
gridLineWidth: 1,
type: 'datetime',
categories: ['01/01/2012', '02/01/2012', '03/01/2012', '04/01/2012', '05/01/2012', '06/01/2012', '07/01/2012', '08/01/2012', '09/01/2012', '10/01/2012'],
tickmarkPlacement: 'on',
labels: {
rotation: -90,
y: -18
},
offset: -13,
lineWidth: 0,
max: 8.6,
},
legend: {
enabled: false
},
yAxis: {
title: {
text: 'Milestones'
},
categories: ['01/01/2012', '02/01/2012', '03/01/2012', '04/01/2012', '05/01/2012', '06/01/2012', '07/01/2012', '08/01/2012', '09/01/2012', '10/01/2012'],
tickmarkPlacement: 'on',
gridLineWidth: 1,
tickPosition: 'inside',
min: 0,
minPadding: 0,
startOnTick: false
},
series: [{
data: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
marker: {
enabled: false
},
color: 'grey',
enableMouseTracking: false,
animation: false
}, {
data: [6, 6, 6, 7, 8, 7, 7, 8, 8.5, 9]
}, {
data: [5, 5, 5, 6, 6.5, 6, 6.5, 7.5, 8]
}, {
data: [4, 4, 4, 5, 5.5, 5.5, 6]
}, {
data: [2, 2.5, 2.5, 3.5, 4]
}, {
data: [1, 1.5, 2]
}, {
type: 'arearange',
data: [[0, 0, -5], [9.2, 9, -5]],
color: 'white',
fillOpacity: 1,
marker: {
enabled: false
},
zIndex: -1,
enableMouseTracking: false,
animation: false
}]
});

There is no such series type. However, you can make it with fake polygon series that will hide half of the chart. Check demo and code posted below.
Code:
Highcharts.chart('container', {
chart: {
height: 500,
width: 500,
events: {
load: function() {
var chart = this,
polygon = chart.series[2].group,
x = polygon.translateX,
y = polygon.translateY;
polygon.translate(x + 3, y + 3);
}
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
opposite: true,
gridLineWidth: 1,
gridLineColor: '#ddd',
tickInterval: 1,
maxPadding: 0,
lineWidth: 0,
max: 10,
min: 0
},
yAxis: {
maxPadding: 0,
tickInterval: 1,
gridLineColor: '#ddd',
max: 10,
min: 0
},
series: [{
name: 'Installation',
data: [8, 6, 7, 8, 7, 6]
}, {
name: 'Manufacturing',
data: [3, 2, 4, 4]
}, {
type: 'polygon',
animation: false,
showInLegend: false,
enableMouseTracking: false,
color: '#fff',
lineWidth: 10,
data: [
[0, 0],
[10, 0],
[10, 10]
]
}, {
type: 'line',
showInLegend: false,
enableMouseTracking: false,
data: [
[0, 0],
[10, 10]
],
color: '#ddd',
lineWidth: 1,
marker: {
enabled: false
}
}]
});

You can use Highcharts SVG Renderer to render triangle that covers half of the chart.
Check this demo: https://jsfiddle.net/BlackLabel/2boma9zs
events: {
load: function() {
var chart = this,
left = chart.plotLeft,
top = chart.plotTop,
width = chart.plotSizeX,
height = chart.plotSizeY;
chart.renderer.path([
'M', left + 1, top + height,
'L', left + width + 1, top,
left + width + 3, top,
left + width + 3, top + height + 3,
left + 1, top + height + 3,
left + 1, top + height
])
.attr({
fill: '#fff'
})
.add()
.toFront();
}
}
