在github发现个好看易用的vue趋势线组件，特此记录。

效果

趋势图生成后效果如上，线条为渐变色，可设置是否平滑。具体线条走势，根据数据动态生成。

使用

安装

javascript 复制代码

npm i vuetrend -S

引入

javascript 复制代码

import Vue from "vue"
import Trend from "vuetrend"

Vue.use(Trend)

使用

javascript 复制代码

<trend
  :data="[0, 2, 5, 9, 5, 10, 3, 5, 0, 0, 1, 8, 2, 9, 0]"
  :gradient="['#6fa8dc', '#42b983', '#2c3e50']"
  auto-draw
  smooth
>
</trend>

其他可配置项

Name	Type	Default	Description	Example
data	Number\|Object	`undefined`	The data accepted by Vue Trend is incredibly simple: An array of y-axis values to graph.	`[120, 149, 193.4, 200, 92]` or `[{ value: 4 }, { value: 6 }, { value: 8 }]`
gradient	String	`['#000']`	Colour can be specified as any SVG-supported format (named, rgb, hex, etc).	`['#0FF', '#F0F', '#FF0']`
gradientDirection	String	`top`	Top, Bottom, Left or Right.
width	Number	auto	Set an explicit width for your SVG.	-
height	Number	auto	Set an explicit height for your SVG.	-
padding	Number	`8`	If you set a very large `strokeWidth` on your line, you may notice that it gets "cropped" towards the edges.	-
smooth	Boolean	`false`	Smooth allows the peaks to be 'rounded' out so that the line has no jagged edges.	-
radius	Number	`10`	When using smoothing , you may wish to control the amount of curve around each point. This prop has no effect if `smooth` isn't set to `true`.	-
autoDraw	Boolean	`false`	Allow the line to draw itself on mount. Set to `true` to enable, and customize using `autoDrawDuration` and `autoDrawEasing`.	-
autoDrawDuration	Number	`2000`	The amount of time, in milliseconds, that the autoDraw animation should span. This prop has no effect if `autoDraw` isn't set to `true`.	-
autoDrawEasing	String	`ease`	The easing function to use for the autoDraw animation. Accepts any transition timing function within the CSS spec (eg. `linear`, `ease`, `ease-in`, `cubic-bezier`...).	-
max	Number	`-Infinity`	Specify max value	-
min	Number	`Infinity`	Specify min value, This is useful if you have multiple lines. See #8	-
