I'm using C3 js to generate a chart. In my chart, I'm currently using stack bars to showing the data.
My code,
<div id="chart"></div>
<script>
var chart = c3.generate({
data: {
columns: [
['Blue', 30, 200, 200, 400, 150, 250],
['Orange', 130, 100, 100, 200, 150, 50],
['Green', 230, 200, 200, 300, 250, 250]
],
type: 'bar',
groups: [
['Blue', 'Orange','Green']
]
}
});
</script>
According to the above code, chart generate as,
Now I need to add an additional 3 line to that chart, as below image,
How can I add Lines to chart using C3 JS? Its document has some line chart with a bar chart. But I can understand how to use it's for my requirement.
You can use data.types to set a chart for each data, Read this: https://c3js.org/reference.html#data-types .And this is a sample code for your problem.
<script>
var chart = c3.generate({
data: {
columns: [
['Blue', 30, 200, 200, 400, 150, 250],
['Orange', 130, 100, 100, 200, 150, 50],
['Green', 230, 200, 200, 300, 250, 250],
['Black', 150, 160, 140, 145, 250, 100],
['Pink', 50, 50, 50, 50, 50, 50],
['Red', 400, 200, 150, 20, 300, 120]
],
types:{
Blue : 'bar',
Orange : 'bar',
Green : 'bar',
Black : 'line',
Pink : 'line',
Red : 'line'
},
groups: [
['Blue', 'Orange','Green']
]
}
});
</script>
Here is how you can achieve it instead of type use types
var chart = c3.generate({
bindto: '#chart',
data: {
columns: [
['Blue', 30, 200, 200, 400, 150, 250],
['Orange', 130, 100, 100, 200, 150, 50],
['Green', 230, 200, 200, 300, 250, 250],
['Black', 30, 200, 200, 400, 150, 250],
['Pink', 130, 100, 100, 200, 150, 50],
['Red', 230, 200, 200, 300, 250, 250]
],
types: {
Blue : 'bar',
Orange : 'bar',
Green : 'bar',
Black : 'line',
Pink : 'line',
Red : 'line'
},
groups: [
['Blue','Orange', 'Green', 'Black','Pink', 'Red']
],
axes: {
Black: 'black',
Pink: 'pink',
Red: 'red',
}
},
color: {
pattern: ['#1f77b4', '#ff7f0e', '#2ca02c','#00000', '#ff69b4', '#ff0000']},
axis: {
black: {
show: true
},pink: {
show: true
},red: {
show: true
}
}
});

In C3 bar charts, when we set Width Ratio to less than 1, then the bar squeezes but the tooltip area does not. How can we set the tool tip to only show over bar not on the whole area like in the following example.
var chart = c3.generate({
data: {
columns: [
['data1', -30, 200, 200, 400, -150, 250],
['data2', 130, 100, -100, 200, -150, 50],
['data3', -230, 200, 200, -300, 250, 250]
],
type: 'bar',
groups: [
['data1', 'data2']
]
},bar: {
width: { ratio: 0.5 }
},
grid: {
y: {
lines: [{value:0}]
}
}
});
setTimeout(function () {
chart.groups([['data1', 'data2', 'data3']])
}, 1000);
setTimeout(function () {
chart.load({
columns: [['data4', 100, -50, 150, 200, -300, -100]]
});
}, 1500);
setTimeout(function () {
chart.groups([['data1', 'data2', 'data3', 'data4']])
}, 2000);

Please help me add rounded corner for stacked chart(grouped bar chart) in c3.js.
I have found something similar here How to get rounded columns in c3.js bar chart
but this is the normal bar chart.
It is not working for stacked chart.
I'm not familiar with d3.js.
Thank you :)

I have a fast question. It is possible to generate that Char in Google Charts? ... And mayby u knew how to do that (any advice or smth)?
Chart1
This white area below the chart is very important.
it's possible
use AreaChart with isStacked: true and set the bottom area to 'transparent'
since isStacked: true, most likely some data manipulation will be required to get the desired outcome
see following working snippet...
google.charts.load('current', {
callback: function () {
new google.visualization.AreaChart(document.getElementById('chart_div')).draw(
google.visualization.arrayToDataTable([
['Year', 'Bottom', 'Area 1', 'Area 2', 'Area 3'],
['2010', 100, 100, 100, 100],
['2020', 110, 120, 130, 140],
['2025', 120, 160, 180, 200],
['2030', 140, 180, 200, 240],
['2035', 200, 240, 280, 320],
['2040', 260, 300, 320, 380],
['2045', 320, 400, 460, 600],
['2050', 400, 480, 600, 800]
]),
{
areaOpacity: 1.0,
colors: ['transparent', 'cyan', 'yellow', 'magenta'],
lineWidth: 1,
isStacked: true,
series: {
0: {
visibleInLegend: false
}
}
}
);
},
packages: ['corechart']
});

So I am having troubles trying to change the colors of my line graph that is generated from JSON from a URL. Here is my code to generate the chart:
var chart = c3.generate({
bindto: '#chart',
data: {
url: '../URL.JSON',
mimeType: 'json',
keys: {
x: 'Date',
value: ["Line1", "Line2", "Line3", "Line4"]
},
type: 'line'
},
axis: {
x: {
type: 'category'
}
},
size: {
height: 500
},
colors: {
'Line1': '#ff0000'
}
});
And here is my JSON format:
[
{'Date': '9/23/2014', 'Line1': 12, 'Line2': 54, 'Line3': 23, 'Line4': 5},
{'Date': '9/22/2014', 'Line1': 56, 'Line2': 18, 'Line3': 25, 'Line4': 0}
]
For some reason the color does not change at all for Line1 with the colors attribute set. So I was wondering if anyone knew how to change the colors to a url generated c3 graph.
Thankyou.
I figured out the answer to my own question so I thought that I would post it here.
I had to add:
color: {
pattern: ['#363FBC', '#363FBC', '#B73540', '#B73540']
}
Instead of:
colors: {
'Line1': '#ff0000'
}
The colors param should be inside the data object, like:
data: {
columns: [
['data1', 30, 20, 50, 40, 60, 50],
['data2', 200, 130, 90, 240, 130, 220],
['data3', 300, 200, 160, 400, 250, 250]
],
type: 'bar',
colors: {
data1: '#ff0000',
data2: '#00ff00',
data3: '#0000ff'
}
}
