# go-charts
|
|
||||||
|
|
||||||
`go-charts`主要分为了下几个模块：
|
|
||||||
|
|
||||||
- `标题`：图表的标题，包括主副标题，位置为图表的顶部
|
|
||||||
- `图例`：图表的图例列表，用于标识每个图例对应的颜色与名称信息，默认为图表的顶部，可自定义位置
|
|
||||||
- `X轴`：图表的x轴，用于折线图、柱状图中，表示每个点对应的时间，位置图表的底部
|
|
||||||
- `Y轴`：图表的y轴，用于折线图、柱状图中，最多可使用两组y轴（一左一右），默认位置图表的左侧
|
|
||||||
- `内容`: 图表的内容，折线图、柱状图、饼图等，在图表的中间区域
|
|
||||||
|
|
||||||
## 标题
|
|
||||||
|
|
||||||
### 常用设置
|
|
||||||
|
|
||||||
标题一般仅需要设置主副标题即可，其它的属性均会设置默认值，常用的方式是使用`TitleTextOptionFunc`设置，其中副标题为可选值，方式如下：
|
|
||||||
|
|
||||||
```go
|
|
||||||
charts.TitleTextOptionFunc("Text", "Subtext"),
|
|
||||||
```
|
|
||||||
|
|
||||||
### 个性化设置
|
|
||||||
|
|
||||||
```go
|
|
||||||
func(opt *charts.ChartOption) {
|
|
||||||
opt.Title = charts.TitleOption{
|
|
||||||
// 主标题
|
|
||||||
Text: "Text",
|
|
||||||
// 副标题
|
|
||||||
Subtext: "Subtext",
|
|
||||||
// 标题左侧位置，可设置为"center"，"right"，数值("20")或百份比("20%")
|
|
||||||
Left: charts.PositionRight,
|
|
||||||
// 标题顶部位置，只可调为数值
|
|
||||||
Top: "20",
|
|
||||||
// 主标题文字大小
|
|
||||||
FontSize: 14,
|
|
||||||
// 副标题文字大小
|
|
||||||
SubtextFontSize: 12,
|
|
||||||
// 主标题字体颜色
|
|
||||||
FontColor: charts.Color{
|
|
||||||
R: 100,
|
|
||||||
G: 100,
|
|
||||||
B: 100,
|
|
||||||
A: 255,
|
|
||||||
},
|
|
||||||
// 副标题字体影响
|
|
||||||
SubtextFontColor: charts.Color{
|
|
||||||
R: 200,
|
|
||||||
G: 200,
|
|
||||||
B: 200,
|
|
||||||
A: 255,
|
|
||||||
},
|
|
||||||
}
|
|
||||||
},
|
|
||||||
```
|
|
||||||
|
|
||||||
### 部分属性个性化设置
|
|
||||||
|
|
||||||
```go
|
|
||||||
charts.TitleTextOptionFunc("Text", "Subtext"),
|
|
||||||
func(opt *charts.ChartOption) {
|
|
||||||
// 修改top的值
|
|
||||||
opt.Title.Top = "20"
|
|
||||||
},
|
|
||||||
```
|
|
||||||
|
|
||||||
## 图例
|
|
||||||
|
|
||||||
### 常用设置
|
|
||||||
|
|
||||||
图例组件与图表中的数据一一对应，常用仅设置其名称及左侧的值即可(可选)，方式如下：
|
|
||||||
|
|
||||||
|
|
||||||
```go
|
|
||||||
charts.LegendLabelsOptionFunc([]string{
|
|
||||||
"Email",
|
|
||||||
"Union Ads",
|
|
||||||
"Video Ads",
|
|
||||||
"Direct",
|
|
||||||
"Search Engine",
|
|
||||||
}, "50"),
|
|
||||||
```
|
|
||||||
|
|
||||||
### 个性化设置
|
|
||||||
|
|
||||||
```go
|
|
||||||
func(opt *charts.ChartOption) {
|
|
||||||
opt.Legend = charts.LegendOption{
|
|
||||||
// 图例名称
|
|
||||||
Data: []string{
|
|
||||||
"Email",
|
|
||||||
"Union Ads",
|
|
||||||
"Video Ads",
|
|
||||||
"Direct",
|
|
||||||
"Search Engine",
|
|
||||||
},
|
|
||||||
// 图例左侧位置，可设置为"center"，"right"，数值("20")或百份比("20%")
|
|
||||||
// 如果示例有多行，只影响第一行，而且对于多行的示例，设置"center", "right"无效
|
|
||||||
Left: "50",
|
|
||||||
// 图例顶部位置，只可调为数值
|
|
||||||
Top: "10",
|
|
||||||
// 图例图标的位置，默认为左侧，只允许左或右
|
|
||||||
Align: charts.AlignRight,
|
|
||||||
// 图例排列方式，默认为水平，只允许水平或垂直
|
|
||||||
Orient: charts.OrientVertical,
|
|
||||||
// 图标类型，提供"rect"与"lineDot"两种类型
|
|
||||||
Icon: charts.IconRect,
|
|
||||||
// 字体大小
|
|
||||||
FontSize: 14,
|
|
||||||
// 字体颜色
|
|
||||||
FontColor: charts.Color{
|
|
||||||
R: 150,
|
|
||||||
G: 150,
|
|
||||||
B: 150,
|
|
||||||
A: 255,
|
|
||||||
},
|
|
||||||
// 是否展示，如果不需要展示则设置
|
|
||||||
// Show: charts.FalseFlag(),
|
|
||||||
// 图例区域的padding值
|
|
||||||
Padding: charts.Box{
|
|
||||||
Top: 10,
|
|
||||||
Left: 10,
|
|
||||||
},
|
|
||||||
}
|
|
||||||
},
|
|
||||||
```
|
|
||||||
|
|
||||||
### 部分属性个性化设置
|
|
||||||
|
|
||||||
```go
|
|
||||||
charts.LegendLabelsOptionFunc([]string{
|
|
||||||
"Email",
|
|
||||||
"Union Ads",
|
|
||||||
"Video Ads",
|
|
||||||
"Direct",
|
|
||||||
"Search Engine",
|
|
||||||
}, "50"),
|
|
||||||
func(opt *charts.ChartOption) {
|
|
||||||
opt.Legend.Top = "10"
|
|
||||||
},
|
|
||||||
```
|
|
||||||
|
|
||||||
## X轴
|
|
||||||
|
|
||||||
### 常用设置
|
|
||||||
|
|
||||||
图表中X轴的展示，常用的设置方式是指定数组即可：
|
|
||||||
|
|
||||||
```go
|
|
||||||
charts.XAxisDataOptionFunc([]string{
|
|
||||||
"Mon",
|
|
||||||
"Tue",
|
|
||||||
"Wed",
|
|
||||||
"Thu",
|
|
||||||
"Fri",
|
|
||||||
"Sat",
|
|
||||||
"Sun",
|
|
||||||
}),
|
|
||||||
```
|
|
||||||
|
|
||||||
### 个性化设置
|
|
||||||
|
|
||||||
```go
|
|
||||||
func(opt *charts.ChartOption) {
|
|
||||||
