Highcharts是一個(gè)制作圖表的純Javascript類庫，主要特性如下：
成都創(chuàng)新互聯(lián)公司公司2013年成立，是專業(yè)互聯(lián)網(wǎng)技術(shù)服務(wù)公司，擁有項(xiàng)目成都網(wǎng)站設(shè)計(jì)、成都做網(wǎng)站網(wǎng)站策劃，項(xiàng)目實(shí)施與項(xiàng)目整合能力。我們以讓每一個(gè)夢(mèng)想脫穎而出為使命，1280元龍門做網(wǎng)站,已為上家服務(wù),為龍門各地企業(yè)和個(gè)人服務(wù),聯(lián)系電話:028-86922220
兼容性：兼容當(dāng)今所有的瀏覽器，包括iPhone、IE和火狐等等；
對(duì)個(gè)人用戶完全免費(fèi)；
純JS，無BS；
支持大部分的圖表類型：直線圖，曲線圖、區(qū)域圖、區(qū)域曲線圖、柱狀圖、餅裝圖、散布圖；
跨語言：不管是PHP、Asp.net還是Java都可以使用，它只需要三個(gè)文件：一個(gè)是Highcharts的核心文件highcharts.js，還有a canvas emulator for IE和Jquery類庫或者M(jìn)ooTools類庫；
提示功能：鼠標(biāo)移動(dòng)到圖表的某一點(diǎn)上有提示信息；
放大功能：選中圖表部分放大，近距離觀察圖表；
易用性：無需要特殊的開發(fā)技能，只需要設(shè)置一下選項(xiàng)就可以制作適合自己的圖表；
時(shí)間軸：可以精確到毫秒；
Highcharts提供大量的選項(xiàng)配置參數(shù)，您可以輕松定制符合用戶要求的圖表，目前官網(wǎng)只提供英文版的開發(fā)配置說明文檔，而中文版的文檔網(wǎng)上甚少，且零散不全。這里，我把Highcharts常用的最核心的參數(shù)選項(xiàng)配置整理成文檔，與大家分享。
Chart圖表區(qū)選項(xiàng)用于設(shè)置圖表區(qū)相關(guān)屬性。
| 參數(shù) | 描述 | 默認(rèn)值 |
| backgroundColor | 設(shè)置圖表區(qū)背景色 | #FFFFFF |
| borderWidth | 設(shè)置圖表邊框?qū)挾?/td> | 0 |

| width | 圖表寬度，默認(rèn)根據(jù)圖表容器自適應(yīng)寬度 | null |
| height | 圖表高度，默認(rèn)根據(jù)圖表容器自適應(yīng)高度 | null |
| margin | 設(shè)置圖表與其他元素之間的間距，數(shù)組，如[0,0,0,0] | [null] |
| plotBackgroundColor | 主圖表區(qū)背景色，即X軸與Y軸圍成的區(qū)域的背景色 | null |
| plotBorderColor | 主圖表區(qū)邊框的顏色，即X軸與Y軸圍成的區(qū)域的邊框顏色 | null |
| plotBorderWidth | 主圖表區(qū)邊框的寬度 | 0 |
| shadow | 是否設(shè)置陰影，需要設(shè)置背景色backgroundColor。 | false |
| reflow | 是否自使用圖表區(qū)域高度和寬度，如果沒有設(shè)置width和height時(shí)，會(huì)自適應(yīng)大小。 | true |
| zoomType | 拖動(dòng)鼠標(biāo)進(jìn)行縮放，沿x軸或y軸進(jìn)行縮放，可以設(shè)置為：'x','y','xy' | '' |
| events | 事件回調(diào)，支持addSeries方法，click方法，load方法，selection方法等的回調(diào)函數(shù)。 |
Color顏色選項(xiàng)用于設(shè)置圖表的顏色方案。
| 參數(shù) | 描述 | 默認(rèn)值 |
| color | 用于展示圖表，折線/柱狀/餅狀等圖的顏色，數(shù)組形式。 | array |
Highcharts已經(jīng)默認(rèn)提供了多種顏色方案，當(dāng)要顯示的圖形多于顏色種類時(shí)，多出的圖形會(huì)自動(dòng)從第一種顏色方案開始選取。自定義顏色方案的方法：

Highcharts.setOptions({
colors: ['#058DC7', '#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655',
'#FFF263', '#6AF9C4']
});
Title標(biāo)題選項(xiàng)用于設(shè)置圖表的標(biāo)題相關(guān)屬性。
| 參數(shù) | 描述 | 默認(rèn)值 |
| text | 標(biāo)題文本內(nèi)容。 | Chart title |
| align | 水平對(duì)齊方式。 | center |
| verticalAlign | 垂直對(duì)齊方式。 | top |
| margin | 標(biāo)題與副標(biāo)題之間或者主圖表區(qū)間的間距。 | 15 |
| floating | 是否浮動(dòng)，如果為true，則標(biāo)題可以偏離主圖表區(qū)，可配合x,y屬性使用。 | false |
| style | 設(shè)置CSS樣式。 | {color: '#3E576F', fontSize: '16px'} |
副標(biāo)題提供的屬性選項(xiàng)與標(biāo)題title大致相同，可參照上述標(biāo)題選項(xiàng)，值得一提的是副標(biāo)題的text選項(xiàng)默認(rèn)為''，即空的，所以默認(rèn)情況下副標(biāo)題不顯示。
X軸選項(xiàng)用于設(shè)置圖表X軸相關(guān)屬性。
| 參數(shù) | 描述 | 默認(rèn)值 |
| categories | 設(shè)置X軸分類名稱，數(shù)組，例如：categories: ['Apples', 'Bananas', 'Oranges'] | [] |
| title | X軸名稱，支持text、enabled、align、rotation、style等屬性 | |
| labels | 設(shè)置X軸各分類名稱的樣式style，格式formatter，角度rotation等。 | array |
| max | X軸最大值(categories為空時(shí))，如果為null，則最大值會(huì)根據(jù)X軸數(shù)據(jù)自動(dòng)匹配一個(gè)最大值。 | null |
| min | X軸最小值(categories為空時(shí))，如果為null，則最小值會(huì)根據(jù)X軸數(shù)據(jù)自動(dòng)匹配一個(gè)最小值。 | array |

| gridLineWidth | 網(wǎng)格(豎線)寬度 | 1 |
| lineColor | 基線顏色 | #C0D0E0 |
| lineWidth | 基線寬度 | 0 |
Y軸選項(xiàng)與上述xAxis選項(xiàng)基本一致，請(qǐng)參照上表中的參數(shù)設(shè)置，不再單獨(dú)列出。
數(shù)據(jù)列選項(xiàng)用于設(shè)置圖表中要展示的數(shù)據(jù)相關(guān)的屬性。
| 參數(shù) | 描述 | 默認(rèn)值 |
| data | 顯示在圖表中的數(shù)據(jù)列，可以為數(shù)組或者JSON格式的數(shù)據(jù)。如：data:[0, 5, 3, 5]，或 data: [{name: 'Point 1',y: 0}, {name: 'Point 2',y: 5}] | '' |
| name | 顯示數(shù)據(jù)列的名稱。 | '' |

Tooltip用于設(shè)置當(dāng)鼠標(biāo)滑向數(shù)據(jù)點(diǎn)時(shí)顯示的提示框信息。
| 參數(shù) | 描述 | 默認(rèn)值 |
| enabled | 是否顯示提示框 | true |
| backgroundColor | 設(shè)置提示框的背景色 | rgba(255, 255, 255, .85) |

第一個(gè)例子：
這個(gè)是從后端api取值，后端再從數(shù)據(jù)庫里取值。
為了不讓整個(gè)頁面刷新，用了ajax做局部刷新

});第二個(gè)例子
這個(gè)和前面是一樣的方式，這里做了多個(gè)引用，也就是可以畫多條線路
這個(gè)圖不是我這的，但下面的代碼是行的通的，可以放到一個(gè)js里面引用，然后通過ajax傳值過去，在前端進(jìn)行數(shù)據(jù)的渲染。
var charts = new Array();
var serverCount = 6;
var lastTimes = new Array();
var max = ${params.int("max")?:120};
$(document).ready(function() {
Highcharts.setOptions({
global: {
useUTC: false
}
});
for (var i = 0; i < serverCount; i++) {
charts[i] = new Highcharts.Chart({
chart: {
renderTo: 'container' + i,
type: 'spline',
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series;
var serverIndex = i;
lastTimes[serverIndex] = 0;
var loadData = function() {
$.getJSON("http://${request.serverName}:${request.serverPort}${request.contextPath}/toolkits/queryStatistics.gsp", {"lasTime":lastTimes[serverIndex],"proxy":true,"index":serverIndex,"max":max}, function(data) {
for (var k = 0; k < series.length; k++) {
for (var j = 0; j < data[k].length; j++) {
var point = data[k][j];
var isShift = series[k].data.length >= max;
console.log("series " + k + ".data.length=" + series[k].data.length);
var lastTime = 0;
if (series[k].data.length > 0)
lastTime = series[k].data[series[k].data.length - 1].x;
if (point[0] > lastTime)
series[k].addPoint([point[0],point[1]], true, isShift);
lastTimes[serverIndex] = point[0];
