怎么使用markdownplus画线图/How to use markdownplus to create a line chart
Summary:
Markdown-plus is a markdown editor, but it also can help us to create charts . Today i will show you how to use markdownplus to create line chart.
Markdown-plus从名字看是markdown的升级版,不仅仅可以让我们用md语法写文章,同时支持让我们创建图表,今天我介绍如何使用markdown-plus 创建连线图。
因为markdown-plus扩展支持了chart.js,所以我们只需要执行简短的代码就可以绘制精美的统计图,而不需要去学习太多chart.js的知识。

下面先看一个简单例子:
演示代码如下:
{
"type": "line",
"data": {
"labels": [
"January",
"February",
"March",
"April",
"May",
"June",
"July"
],
"datasets": [
{
"label": "# of bugs",
"fill": false,
"lineTension": 0.1,
"backgroundColor": "rgba(75,192,192,0.4)",
"borderColor": "rgba(75,192,192,1)",
"borderCapStyle": "butt",
"borderDash": [],
"borderDashOffset": 0,
"borderJoinStyle": "miter",
"pointBorderColor": "rgba(75,192,192,1)",
"pointBackgroundColor": "#fff",
"pointBorderWidth": 1,
"pointHoverRadius": 5,
"pointHoverBackgroundColor": "rgba(75,192,192,1)",
"pointHoverBorderColor": "rgba(220,220,220,1)",
"pointHoverBorderWidth": 2,
"pointRadius": 1,
"pointHitRadius": 10,
"data": [
65,55,
59,55,
80,3,
81,3,
56,4,
55.5,
40
],
"spanGaps": false
}
]
},
"options": {}
}
知识点1:Markdown语法格式输入,以及如何支持扩展语言
markdown 里面代码是使用 英文状态下的4个顿号括起来的,如下:
····
代码 //此时,这部分内容是不被执行的,在markdown会直接显示出来。
····
效果是代码高亮,区别于别的内容。
想要实现进度图,markdown语法是不支持的,而markdown-plus支持语法扩展,所以我们可以在markdown-plus输入别的语法来实现我们需要的功能。
····chart
代码区域
····
这里我们使用扩展语法 chart来制作进度图图,此时,代码区域的内容会被执行。
知识点2:声明连线图
"type": "line",
type为图表类型,line即为连线图。
知识点3:设置X轴标签名称
"data": {
"labels": [
"January",
"February",
"March",
"April",
"May",
"June",
"July"
],
labels即为标签,这里设置的是显示在X轴上面的各个标签名称。用双引号括起来,用逗号隔开。例子如下:
知识点4:设置连线图外观
"datasets": [
{
"label": "# of bugs",
"fill": false,
"lineTension": 0.1,
"backgroundColor": "rgba(75,192,192,0.4)",
"borderColor": "rgba(75,192,192,1)",
"borderCapStyle": "butt",
"borderDash": [],
"borderDashOffset": 0,
"borderJoinStyle": "miter",
"pointBorderColor": "rgba(75,192,192,1)",
"pointBackgroundColor": "#fff",
"pointBorderWidth": 1,
"pointHoverRadius": 5,
"pointHoverBackgroundColor": "rgba(75,192,192,1)",
"pointHoverBorderColor": "rgba(220,220,220,1)",
"pointHoverBorderWidth": 2,
"pointRadius": 1,
"pointHitRadius": 10,
}
]
label 图例,显示在表格上方,如下:
其余参数介绍:
Line Configuration 线性设置
Name | Type | Default | Description |
---|---|---|---|
tension | Number | 0.4 | 默认贝塞尔曲线张力设置,设置为0时,没有曲线张力 |
backgroundColor | Color | 'rgba(0,0,0,0.1)' | 默认填充颜色 |
borderWidth | Number | 3 | 线的宽度 |
borderColor | Color | 'rgba(0,0,0,0.1)' | 默认线的颜色 |
borderCapStyle | String | 'butt' | 默认线的一端的样式 |
borderDash | Array | [] | 默认线条波折线样式 |
borderDashOffset | Number | 0.0 | 默认波折线间距 |
borderJoinStyle | String | 'miter' | 默认线波折连接样式 |
capBezierPoints | Boolean | true | 如果值为true 则控制图表内部点,为false 则不控制 |
fill | Boolean | true | 如果是true则为线填充颜色 |
stepped | Boolean | false | 如果是true则线的样式是折线,张力会无效 |
Point Configuration点型设置
Name | Type | Default | Description |
---|---|---|---|
radius | Number | 3 | 默认半径 |
pointStyle | String | 'circle' | 默认样式 |
backgroundColor | Color | 'rgba(0,0,0,0.1)' | 默认填充颜色 |

hoverRadius | Number | 4 | 鼠标放上去是的默认半径 |
hoverBorderWidth | Number | 1 | 鼠标放上去时默认线宽 |
Rectangle Configuration矩形设置

borderWidth | Number | 0 | 默认条的线宽 |
borderColor | Color | 'rgba(0,0,0,0.1)' | 默认条的线的颜色 |
borderSkipped | String | 'bottom' | 默认的跳跃边界 |
知识点5:录入数据
"data": [
65,
59,
80,
80,
50,
55,
40
],
此部分代码还是要写在dataset里,data:数据。格式 "data":{data1,data2,data3……}
x轴标签有多少个就录入多少个数据。
下面是个简单实例:
代码如下:
{
"type": "line",
"data": {
"labels": [
"A",
"B",
"C",
"D",
"E",
"F",
"G",
"H",
"I",
"J",
"K",
"L",
"M",
"N"
],
"datasets": [
{
"label": "# of bugs ",
"fill": true,
"lineTension": 0.6,
"backgroundColor": "rgba(25,102,192,0.1)",
"borderColor": "rgba(75,92,192,1)",
"borderCapStyle": "butt",
"borderDash": [],
"borderDashOffset": 1,
"borderJoinStyle": "miter",
"pointBorderColor": "rgba(175,192,192,1)",
"pointBackgroundColor": "#fff",
"pointBorderWidth": 1,
"pointHoverRadius": 5,
"pointHoverBackgroundColor": "rgba(175,192,192,1)",
"pointHoverBorderColor": "rgba(225,225,220,1)",
"pointHoverBorderWidth": 2,
"pointRadius": 1,
"pointHitRadius": 11,
"data": [
65,
59,
80,
81,
56,
55,
40,
15,
5,
11.3,
21,
6,
5,
10
],
"spanGaps": false
}
]
},
"options": {}
}
