Hi,
How can I change the colors of the lines and text in the image bellow.
https://codesandbox.io/s/wy90g2?file=/index.js
option = {
grid:{
show: false
},
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [
{
data: [120, 200, 150, 80, 70, 110, 130],
type: 'bar'
}
]
};
Thanks
I'd like to show bar chart with categories on x-axis (say months), multiple series and each bar element containing multiple data points (value shown on y-axis, the rest in tooltip).
It's relatively easy to do it using series.data:
option = {
tooltip: {
trigger: 'axis',
axisPointer: {
// Use axis to trigger tooltip
type: 'shadow' // 'shadow' as default; can also be 'line' or 'shadow'
}
},
xAxis: {
type: 'category'
},
yAxis: {
type: 'value'
},
series: [
{
name: 'Series A',
type: 'bar',
label: {
show: true
},
data: [
['Jul', 320, 2],
['June', 119, 4]],
encode: {
tooltip: [0,1,2]
}
}
,
{
name: 'Series B',
type: 'bar',
label: {
show: true
},
data: [
['Jul', 420, 3],
['June', 123, 5]],
encode: {
tooltip: [0,1,2]
}
}
]
};
I'm wondering how it can be refactored best to use dataset? I have two ideas, I wonder what are pros & cons.. Maybe there is other, cleaner way to express it.
Ideally instead of one big array I'd prefer to have array of objects so dimensions are named.
Solution: One dataset, shifting indices
option = {
tooltip: {
trigger: 'axis',
axisPointer: {
// Use axis to trigger tooltip
type: 'shadow' // 'shadow' as default; can also be 'line' or 'shadow'
}
},
legend: {},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis: {
type: 'category'
//, data: ['Jul', 'June']
},
yAxis: {
type: 'value'
},
dataset: {
source: [
['Jul', 320, 2, 420, 3],
['June', 119, 4, 123, 5]]
},
series: [
{
name: 'Series A',
type: 'bar',
label: {
show: true
},
encode: {
y: 1,
tooltip: [0,1,2]
}
}
,
{
name: 'Series B',
type: 'bar',
label: {
show: true
},
encode: {
y: 3,
tooltip: [0,3,4]
}
}
]
};
With named dimensions it would look like:
dataset: {
source: [
[month:'Jul', SeriesA_dim1: 320, SeriesA_dim2: 2, SeriesB_dim1: 420, SeriesB_dim2: 3],
[month:'Jun', SeriesA_dim1: 119, SeriesA_dim2: 4, SeriesB_dim1: 123 SeriesB_dim2: 5],
},
....
encode: {
y: 'SeriesB_dim1',
tooltip: ['month','SeriesB_dim1','SeriesB_dim2']
}
Solution 2: Multiple datasets
option = {
tooltip: {
trigger: 'axis',
axisPointer: {
// Use axis to trigger tooltip
type: 'shadow' // 'shadow' as default; can also be 'line' or 'shadow'
}
},
legend: {},
xAxis: {
type: 'category'
},
yAxis: {
type: 'value'
},
dataset: [{
source: [
['Jul', 320, 2],
['June', 119, 4]]
},
{
source: [
['Jul', 420, 3],
['June', 123, 5]]
}],
series: [
{
name: 'Series A',
type: 'bar',
label: {
show: true
},
// data: [
// ['Jul', 320, 2],
// ['June', 119, 4]],
encode: {
tooltip: [0,1,2]
}
}
,
{
name: 'Series B',
type: 'bar',
label: {
show: true
},
// data: [
// ['Jul', 420, 3],
// ['June', 123, 5]],
datasetIndex: 1,
encode: {
tooltip: [0,1,2]
}
}
]
};
With named dimensions it would look like:
dataset: [{
source: [
[month:'Jul', dim1: 320, dim2: 2],
[month:'June', dim1: 119, dim2: 4]]
},
{
source: [
[month:'Jul', dim1: 420, dim2: 3],
[month:'June', dim1: 123, dim2: 5]]
}],
....
encode: {
y: 'dim1', // the default would be likely working as well
tooltip: ['month','dim1','dim2']
}
I am trying to add a visual map according to the y axis in echarts.
Taking one of their example:
https://echarts.apache.org/examples/en/editor.html?c=area-pieces
The results looks as follow:
what I'm trying to achieve is:
Obviously here, I have just rotated the picture by 90 degree.
How can this be achieve in echarts directly (so not by saving the picture first)?
The simplest solution would be inverting the axis, data index, and visual map axis. See chart options below:
option = {
backgroundColor: '#fff',
xAxis: {
type: 'value',
boundaryGap: [0, '30%'],
position: 'top'
},
yAxis: {
type: 'category',
boundaryGap: false
},
visualMap: {
type: 'piecewise',
show: false,
dimension: 1,
seriesIndex: 0,
pieces: [{
gt: 1,
lt: 3,
color: 'rgba(0, 180, 0, 0.5)'
}, {
gt: 5,
lt: 7,
color: 'rgba(0, 180, 0, 0.5)'
}]
},
series: [
{
type: 'line',
smooth: 0.6,
symbol: 'none',
lineStyle: {
color: 'green',
width: 5
},
markLine: {
symbol: ['none', 'none'],
label: {show: false},
data: [
{yAxis: 1},
{yAxis: 3},
{yAxis: 5},
{yAxis: 7}
]
},
areaStyle: {},
data: [
[200, '2019-10-10'],
[400, '2019-10-11'],
[650, '2019-10-12'],
[500, '2019-10-13'],
[250, '2019-10-14'],
[300, '2019-10-15'],
[450, '2019-10-16'],
[300, '2019-10-17'],
[100, '2019-10-18']
]
}
]
};
Result:

Trying to get a single split line to render on a stacked bar graph.
Here's the code:
options = {
tooltip: {
trigger: 'item',
axisPointer: {
type: 'shadow'
}
},
legend: {
data: ['Graph 1', 'Graph 2']
},
grid: {
left: '7%',
right: '5%',
bottom: '3%',
containLabel: true
},
xAxis: [
{
type: 'category',
data: [40, 41, 42, 43, 44],
axisLabel: {
interval: 1
},
splitLine: {
show: true,
interval: function (param) {
//return param === 1; //what I'm trying to get it to do
return param > 0 && param < 2; //this doesn't work
//return param > 0; //this works, but adds a split line to everything above 1 as well, not what I want. vice versa (param < 2) also works, but again not what I want
},
lineStyle: {
type: 'dashed',
width: 2,
color: '#767676'
}
}
}
],
yAxis: [
{
type: 'value',
name: 'Y',
nameLocation: 'middle',
nameTextStyle: {
padding: [0, 0, 8, 0],
color: '#767676',
fontSize: 14
},
axisTick: {
show: false
},
axisLabel: {
show: false
},
splitLine: {
show: false
}
}
],
series: [
{
name: 'Graph 1',
type: 'bar',
barWidth: 20,
stack: 'Graph',
itemStyle: {
color: '#db0011'
},
data: [8000, 10000, 12000, 16000, 20000]
},
{
name: 'Graph 2',
type: 'bar',
barWidth: 20,
barGap: '-100%',
stack: 'Graph',
itemStyle: {
color: '#00a69d'
},
data: [4000, 5000, 6000, 8000, 10000]
}
]
};
As per the above code,
param > 0 works but will add a split line to everything beyond 1 (1 and 2)
likewise, param < 2 will add a split line to everything before 2 (0 and 1)
param > 0 and param < 2 doesn't work (no split line appears)
setting a fixed number causes a split line to appear at the end of the graph as well, despite not being in the right interval (e.g. if my items went from 40 - 80 and I set an interval of 7, then the split line would appear before 47, 54, 61, 68, 75 and on 40 and 80)
How do I get a single split line to appear?
I've also seen Echarts how do you add dashed vertical line in between specific bars on bar chart?, however I don't have enough knowledge on how to modify this to work with a stacked bar chart.
How I want it to look like:
The way I ended up resolving this is:
var option = {
tooltip: {
trigger: 'item',
axisPointer: {
type: 'shadow'
}
},
legend: {
data: ['Graph 1', 'Graph 2']
},
grid: {
left: '7%',
right: '5%',
bottom: '3%',
containLabel: true
},
xAxis: [
{
type: 'category',
data: [40, '', 41, '', 42, '', 43, '', 44],
axisLabel: {
interval: 1
},
splitLine: {
show: false
}
}
],
yAxis: [
{
type: 'value',
name: 'Y',
nameLocation: 'middle',
nameTextStyle: {
padding: [0, 0, 8, 0],
color: '#767676',
fontSize: 14
},
axisTick: {
show: false
},
axisLabel: {
show: false
},
splitLine: {
show: false
}
}
],
series: [
{
name: 'Graph 1',
type: 'bar',
barWidth: 20,
stack: 'Graph',
data: [8000, 0, 10000, 0, 12000, 0, 16000, 0, 20000],
markLine: {
silent: true,
symbol: 'none',
label: {
show: false
},
data: [
{
name: "Test",
xAxis: 2.5,
lineStyle: {
color: '#767676',
width: 2,
type: 'dashed'
}
},
]
}
},
{
name: 'Graph 2',
type: 'bar',
barWidth: 20,
barGap: '-100%',
stack: 'Graph',
data: [4000, 0, 5000, 0, 6000, 0, 8000, 0, 10000]
}
]
};
A few things to note:
Add a bunch of empty string entries for your labels (x-axis). As can be seen above, data is [40, '', 41, '', 42, '', 43, '', 44] instead of [40, 41, 42, 43, 44].
Add zeroes in your graph series relative to where you inserted empty string labels in your x-axis data above (e.g. 4000, 0, 5000, 0, 6000, 0, 8000, 0, 10000). Do this for each graph you have.
In any of the graphs, insert the above markLine syntax I added to Graph 1. You will need to adjust the value of xAxis until you get the middle point.

Hope someone can help, I've search examples of this but can't get them to work on my particular setup. I have a stacked column chart in Highcharts representing 5 sets of data for each day of the week.
I then select a day to see an hourly breakdown of the day, I have the data coming through but I can't get the 5 values I have for each hour to stack on top of each other. (in the same way as the first chart) - ideally this second chart would be an area chart)
Here is my code:
$(function () {
Highcharts.setOptions({

drillUpText: 'Reset'
}
});
// Create the chart

s = 'Day: <b>' + point.name + '</b><br/>Utilisation: <b>' + this.y + '% </b><br/>Select to view hours';

I've shown the first drilldown data so you can see the structure. Any help would be appreciated.
Thanks

You can change the type of drill-down data from ['time', data] to [time, data]:
data: [
['8', 13.77],
['8', 2.74],
['8', 1.27],
['8', 2.64],
['8', 2.28],
['9', 29.30],
['9', 6.44],
['9', 3.79],
['9', 5.11],
['9', 5.32],
...
]
to:
data: [
[8, 13.77],
[8, 2.74],
[8, 1.27],
[8, 2.64],
[8, 2.28],
[9, 29.30],
[9, 6.44],
[9, 3.79],
[9, 5.11],
[9, 5.32],
...
]
And I also changed the tooltip.formatter to show the correct tooltip for drill-downs. Here's the DEMO
