图表highcharts联合jquery ajax 后端取数据前端图表渲染

发布时间:2020-07-09 21:32:50 来源:网络 阅读:17530 作者:rfyiamcool 栏目:web开发

Highcharts是一个制作图表的纯Javascript类库,主要特性如下:

  • 兼容性:兼容当今所有的浏览器,包括iPhone、IE和火狐等等;

  • 对个人用户完全免费;

  • 纯JS,无BS;

  • 支持大部分的图表类型:直线图,曲线图、区域图、区域曲线图、柱状图、饼装图、散布图;

  • 跨语言:不管是PHP、Asp.net还是Java都可以使用,它只需要三个文件:一个是Highcharts的核心文件highcharts.js,还有a canvas emulator for IE和Jquery类库或者MooTools类库;

  • 提示功能:鼠标移动到图表的某一点上有提示信息;

  • 放大功能:选中图表部分放大,近距离观察图表;

  • 易用性:无需要特殊的开发技能,只需要设置一下选项就可以制作适合自己的图表;

  • 时间轴:可以精确到毫秒;


Highcharts提供大量的选项配置参数,您可以轻松定制符合用户要求的图表,目前官网只提供英文版的开发配置说明文档,而中文版的文档网上甚少,且零散不全。这里,我把Highcharts常用的最核心的参数选项配置整理成文档,与大家分享。

Chart:图表区选项

Chart图表区选项用于设置图表区相关属性。

参数描述默认值
backgroundColor设置图表区背景色#FFFFFF
borderWidth设置图表边框宽度0
borderRadius设置图表边框圆角角度5
renderTo图表放置的容器,一般在html中放置一个DIV,获取DIV的id属性值null
defaultSeriesType默认图表类型line, spline, area, areaspline, column, bar, pie , scatter0
width图表宽度,默认根据图表容器自适应宽度null
height图表高度,默认根据图表容器自适应高度null
margin设置图表与其他元素之间的间距,数组,如[0,0,0,0][null]
plotBackgroundColor主图表区背景色,即X轴与Y轴围成的区域的背景色null
plotBorderColor主图表区边框的颜色,即X轴与Y轴围成的区域的边框颜色null
plotBorderWidth主图表区边框的宽度0
shadow是否设置阴影,需要设置背景色backgroundColor。false
reflow是否自使用图表区域高度和宽度,如果没有设置width和height时,会自适应大小。true
zoomType拖动鼠标进行缩放,沿x轴或y轴进行缩放,可以设置为:'x','y','xy'''
events事件回调,支持addSeries方法,click方法,load方法,selection方法等的回调函数。
Color:颜色选项

Color颜色选项用于设置图表的颜色方案。

参数描述默认值
color用于展示图表,折线/柱状/饼状等图的颜色,数组形式。array

Highcharts已经默认提供了多种颜色方案,当要显示的图形多于颜色种类时,多出的图形会自动从第一种颜色方案开始选取。自定义颜色方案的方法:


Highcharts.setOptions({
   colors: ['#058DC7', '#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655',
'#FFF263', '#6AF9C4']
});
Title:标题选项

Title标题选项用于设置图表的标题相关属性。

参数描述默认值
text标题文本内容。Chart title
align水平对齐方式。center
verticalAlign垂直对齐方式。top
margin标题与副标题之间或者主图表区间的间距。15
floating是否浮动,如果为true,则标题可以偏离主图表区,可配合x,y属性使用。false
style设置CSS样式。{color: '#3E576F',
fontSize: '16px'}
Subtitle:副标题选项

副标题提供的属性选项与标题title大致相同,可参照上述标题选项,值得一提的是副标题的text选项默认为'',即空的,所以默认情况下副标题不显示。

xAxis:X轴选项

X轴选项用于设置图表X轴相关属性。

参数描述默认值
categories设置X轴分类名称,数组,例如:categories: ['Apples', 'Bananas', 'Oranges'][]
titleX轴名称,支持text、enabled、align、rotation、style等属性
labels设置X轴各分类名称的样式style,格式formatter,角度rotation等。array
maxX轴最大值(categories为空时),如果为null,则最大值会根据X轴数据自动匹配一个最大值。null
minX轴最小值(categories为空时),如果为null,则最小值会根据X轴数据自动匹配一个最小值。array
gridLineColor网格(竖线)颜色#C0C0C0
gridLineWidth网格(竖线)宽度1
lineColor基线颜色#C0D0E0
lineWidth基线宽度0
yAxis:Y轴选项

Y轴选项与上述xAxis选项基本一致,请参照上表中的参数设置,不再单独列出。

Series:数据列选项

数据列选项用于设置图表中要展示的数据相关的属性。

参数描述默认值
data显示在图表中的数据列,可以为数组或者JSON格式的数据。如:data:[0, 5, 3, 5],或
data: [{name: 'Point 1',y: 0}, {name: 'Point 2',y: 5}]
''
name显示数据列的名称。''
type数据列类型,支持 area, areaspline, bar, column, line, pie, scatter or splineline
plotOptions:数据点选项

plotOptions用于设置图表中的数据点相关属性。plotOptions根据各种图表类型,其属性设置略微有些差异,现将常用选项列出来。

参数描述默认值
enabled是否在数据点上直接显示数据false
allowPointSelect是否允许使用鼠标选中数据点false
formatter回调函数,格式化数据显示内容formatter: function() {return this.y;}
Tooltip:数据点提示框

Tooltip用于设置当鼠标滑向数据点时显示的提示框信息。

参数描述默认值
enabled是否显示提示框true
backgroundColor设置提示框的背景色rgba(255, 255, 255, .85)
borderColor提示框边框颜色,默认自动匹配数据列的颜色auto
borderRadius提示框圆角度5
shadow是否显示提示框阴影true
style设置提示框内容样式,如字体颜色等color:'#333'
formatter回调函数,用于格式化输出提示框的显示内容。返回的内容支持html标签如:<b>, <strong>, <i>, <em>, <br/>, <span>2
Legend:图例选项

legend用于设置图例相关属性。

参数描述默认值
layout显示形式,支持水平horizontal和垂直verticalhorizontal
align对齐方式。center
backgroundColor图例背景色。null
borderColor图例边框颜色。#909090
borderRadius图例边框角度5
enabled是否显示图例true
floating是否可以浮动,配合x,y属性。false
shadow是否显示阴影false
style设置图例内容样式''



第一个例子:


这个是从后端api取值,后端再从数据库里取值。

为了不让整个页面刷新,用了ajax做局部刷新

第二个例子


这个和前面是一样的方式,这里做了多个引用,也就是可以画多条线路

这个图不是我这的,但下面的代码是行的通的,可以放到一个js里面引用,然后通过ajax传值过去,在前端进行数据的渲染。


图表highcharts联合jquery ajax 后端取数据前端图表渲染
