I am developing a layered column chart using ComboChart on Angular google charts. Although I've separated two series of bar charts in two different axis, being able to find a bar in front of the other, like needed, I can't change the width of one of the series only. I want a result like the amCharts Layered Column Chart:
Right now, the chart looks like:
Current chart - Angular google charts
Also, if there is a way to share the same y axis while keeping one bar in front of the other, instead of staking then, it would be great.
The code I've been using for options of the angular google chart:
this.options =
{
colors: ['#1E90FF', '#f39800'],
hAxis: {
title: 'haxisTitle',
type: 'category'
},
vAxis:{
title: 'Value',
minValue: 0,
format: this.numberFormat
},
seriesType: 'bars',
bar: {1: {groupWidth: "30"}},
series:
{
0: {
targetAxisIndex: 0
},
1: {
targetAxisIndex: 1,
}
},
vAxes: {
0: {
title: 'Altered Value',
label:'Altered Value',
viewWindow: { // <-- set view window
min: 0,
max: this.maxValue + 0.1*this.maxValue, // Sets the maximun value of altered or real value to the window size (both axis)
},
format: this.numberFormat,
type: 'bars'
},
1: {
title: 'Real Value',
label:'Real Value',
viewWindow: { // <-- set view window
min: 0,
max: this.maxValue + 0.1*this.maxValue,
},
format: this.numberFormat,
type: 'bars'
}
},
aggregationTarget: 'auto',
stackSeries: true,
isStacked : true,
explorer: {
actions: ['dragToZoom', 'rightClickToReset'],
keepInBounds: true,
maxZoomIn: 4.0
}
};
}The chart shows the data correctly, the only problem is the layout.
