# Liquid Fill Chart
Liquid Fill Chart plugin for [Apache ECharts](https://github.com/apache/echarts), which is usually used to represent data in percentage.
## Install ECharts
To use ECharts plugins, you need to include the plugin JavaScript file after ECharts file.
```html
```
ECharts can be downloaded at [GitHub dist directory](https://github.com/apache/echarts/tree/master/dist) or [Download page of Official Website](https://echarts.apache.org/zh/download.html) (in Chinese).
#### NOTE
>
> The minimum package of ECharts required by LiquidFill Chart is [simple version](https://github.com/apache/echarts/blob/master/dist/echarts.simple.js) on GitHub, or selecting nothing in [online builder](https://echarts.apache.org/zh/download.html) (in Chinese). If you need other chart types or components in your other chart, you should include them accordingly.
## Install echarts-liquidfill with npm
```sh
# install echarts as peer dependency
npm install echarts
npm install echarts-liquidfill
```
NOTE:
echarts-liquidfill@3 is compitable with echarts@5
echarts-liquidfill@2 is compitable with echarts@4
Import:
```js
import * as echarts from 'echarts';
import 'echarts-liquidfill'
```
Or:
```js
import * as echarts from 'echarts/core';
import 'echarts-liquidfill'
```
[Here](https://codesandbox.io/s/brave-rosalind-dj280?file=/src/index.js) is the basic example on CodeSandbox
## Download echarts-liquidfill from GitHub
You may download the lastest ECharts files on [ECharts official site](https://echarts.apache.org/zh/download.html) and download this plugin in [dist directory](https://github.com/ecomfe/echarts-liquidfill/tree/master/dist).
**Note that if you need tooltip for Liquid Fill Chart, you need the complete ECharts version. Otherwise, the simple version will be competent.**
## Important Notes
### Omitted `normal`
Since [ECharts v4.0.0]((https://github.com/apache/echarts/releases/tag/4.0.0)), `normal` is no longer needed for `itemStyle` or `label`.
### Flatten `textStyle`
Since [ECharts v3.7.0](https://github.com/apache/echarts/releases/tag/3.7.0), `textStyle` option is flatten, so that `series.label[normal|emphasis].textStyle.xxx` is now can be written in `series.label[normal|emphasis].textStyle`. This is supported from [echarts-liquidfill](https://github.com/ecomfe/echarts-liquidfill/releases/tag/v1.0.6) v1.0.6. So if you found examples with `textStyle` in old demo, don't be too surprised.

## Examples
### A Simple Example
To create a Liquid Fill Chart, you need to have a series with type of `'liquidFill'`. A basic option may be:
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6]
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xr1XplzB4e)
### Multiple Waves
It is easy to create a liquid fill chart will multiple waves, either to represent multiple data, or to improve the visual effect of the chart.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3]
}]
};
```
This creates a chart wit waves at position of 60%, 50%, 40%, and 30%.
[Run](https://www.makeapie.com/editor.html?c=xSyIEWMBNl)
### Color and Opacity
To set colors for liquid fill chart series, set `color` to be an array of colors. To set opacity, use `itemStyle.opacity` and `itemStyle.emphasis.opacity` for normal style and hover style.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.5, 0.4, 0.3],
color: ['red', '#0f0', 'rgb(0, 0, 255)'],
itemStyle: {
opacity: 0.6
},
emphasis: {
itemStyle: {
opacity: 0.9
}
}
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xrJpDC704l)
You may also set the color and opacity of a single data item by:
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.5, 0.4, {
value: 0.3,
itemStyle: {
color: 'red',
opacity: 0.6
},
emphasis: {
itemStyle: {
opacity: 0.9
}
}
}]
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xBJPCRXR4l)
### Static Waves
To provent the waves from moving left or right, you may simply set `waveAnimation` to be `false`. To disable the animation of waves raising, set `animationDuration` and `animationDurationUpdate` to be 0.
```js
var option = {
series: [{
type: 'liquidFill',
waveAnimation: false,
animationDuration: 0,
animationDurationUpdate: 0,
data: [0.6, 0.5, 0.4, 0.3]
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xH1VfVVREx)
### Still Water
You may set the `amplitude` to be 0 to make still waves.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
amplitude: 0,
waveAnimation: 0
}]
};
```
It is recommended to set `waveAnimation` to be false in this case to disable animation for performance consideration.
[Run](https://www.makeapie.com/editor.html?c=xHy1NHVCNx)
### Change A Single Wave
To change a single wave, overwrite the options in data item.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, {
value: 0.5,
direction: 'left',
itemStyle: {
color: 'red'
}
}, 0.4, 0.3]
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xry6CHNCVl)
### Background Style
You can use backgroundStyle option to set the stroke, fill style of background shape.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
backgroundStyle: {
borderWidth: 5,
borderColor: 'red',
color: 'yellow'
}
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xSkJoa_kBx)
### Outline Style
To hide the outline, just set `outline.show` to be `false`.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
outline: {
show: false
}
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xSySxR_JBg)
### Shape
Shape of water fill chart. It can be:
- one of the default symbols: `'circle'`, `'rect'`, `'roundRect'`, `'triangle'`, `'diamond'`, `'pin'`, `'arrow'`;
- `'container'`: a shape that fully fills the container.
- an SVG path starting with `'path://'`.
```js
var options = [{
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
shape: 'diamond'
}]
}];
```

}
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xH1HouM9Sl)
### Animation
Generally speaking, there are two types of animations in liquid fill charts.
The first type is initial animation, which has the effect of wave raising. The easing method of this animation is controlled with `animationEasing` and its duration with `animationDuration`.
The second type is the update animation, which is usually used when data changes and wave height changes. They are controlled with `animationEasingUpdate` and `animationDurationUpdate`.
For example, to disable the raising animation and set update animation time to be two seconds with `cubicOut` easing, you can use the following option:
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
animationDuration: 0,
animationDurationUpdate: 2000,
animationEasingUpdate: 'cubicOut'
}]
};
chart.setOption(option);
setTimeout(function () {
chart.setOption({
series: [{
type: 'liquidFill',
data: [0.8, 0.6, 0.4, 0.2]
}]
})
}, 3000);
```
[Run](https://www.makeapie.com/editor.html?c=xSk8I5JcHe)
### Change Text
By default, the text label of liquid fill chart displays percentage of the first data. For example, for a chart with data `[0.6, 0.5, 0.4, 0.3]`, default text is `60%`.
To change the text, you may use `label.formatter`, which can be set to a string or function.
If it is a string, `{a}` refers to series name, `{b}` to data name, and `{c}` to data value.
```js
var option = {
series: [{
type: 'liquidFill',
name: 'Liquid Fill',
data: [{
name: 'First Data',
value: 0.6
}, 0.5, 0.4, 0.3],
label: {
formatter: '{a}\n{b}\nValue: {c}',
fontSize: 28
}
}]
};
```
Label text of this example is `'Liquid Fill\nFirst Data\nValue: 0.6'`.
[Run](https://www.makeapie.com/editor.html?c=xrkwSn1qHx)
This has the same result as using `formatter` as a function:
```js
var option = {
series: [{
type: 'liquidFill',
name: 'Liquid Fill',
data: [{
name: 'First Data',
value: 0.6
}, 0.5, 0.4, 0.3],
label: {
formatter: function(param) {
return param.seriesName + '\n'
+ param.name + '\n'
+ 'Value:' + param.value;
},
fontSize: 28
}
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xHk5831cHg)
Text position is at the center by default. `label.position` can be set to be `'inside'`, `'left'`, `'right'`, `'top'`, `'bottom'`, or horizontal and vertical positions like `['10%', '20%']`, which means `'10%'` to the left (controlled by `label.align`, which can be `'left'`, `'center'`, or `'right'`) and `'20%'` to the top (controlled by `label.baseline`, which can be `'top'`, `'middle'`, or `'bottom'`).
### Shadow
By default, waves and outline have shadow on them. Here's how to change them.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
itemStyle: {
shadowBlur: 0
},
outline: {
borderDistance: 0,
itemStyle: {
borderWidth: 5,
borderColor: '#156ACF',
shadowBlur: 20,
shadowColor: 'rgba(255, 0, 0, 1)'
}
}
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xrJO4CyqSl)
### Tooltip
To add tooltip:
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6],
name: 'Liquid Fill'
}],
tooltip: {
show: true
}
};
```
[Run](https://www.makeapie.com/editor.html?c=xSJqXeg5He)
### Click Event
To add click event on waves:
```js
chart.setOption(option);
chart.on('click', function() {
console.log(arguments);
// do something useful here
});
```
Like any other chart types, the above code will only trigger events on waves. If you want to track events on the whole canvas or specific elements, you may add listener to zrender like:
```js
chart.getZr().on('click', function() {
console.log(arguments);
});
```
### Non-interactable
To make an element (e.g., a wave) non-interactable, simply set `silent` to be `true`.
```js
var option = {
series: [{
type: 'liquidFill',
data: [0.6, 0.5, 0.4, 0.3],
silent: true
}]
};
```
[Run](https://www.makeapie.com/editor.html?c=xSJqev71Jb)
