java怎么從數(shù)據(jù)庫里獲得動態(tài)數(shù)據(jù)生成統(tǒng)計圖
我這個是使用的echarts的餅圖，如果需要使用到其他的圖形，可以在echarts的官網(wǎng)上面去找找，上面各種的圖都有例子
option = {
title : {
//圖中2的位置
text: '某站點用戶訪問來源',
subtext: '純屬虛構(gòu)',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{a} br/ : {c} (vbb75nf%)"
},
legend: {
orient: 'vertical',
left: 'left',
data: ['直接訪問','郵件營銷','聯(lián)盟廣告','視頻廣告','搜索引擎']//圖中1的位置
},
series : [ ? //圖中3的位置
{
name: '訪問來源',
type: 'pie',
radius : '55%',
center: ['50%', '60%'],
data:[
//這下面就是你從數(shù)據(jù)庫中查詢的結(jié)果
{value:335, name:'直接訪問'},
{value:310, name:'郵件營銷'},
{value:234, name:'聯(lián)盟廣告'},
{value:135, name:'視頻廣告'},
{value:1548, name:'搜索引擎'}
],
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
} }]};
數(shù)據(jù)具體怎么從后臺傳送到前臺來，樓主應該知道的吧，我這兒就不說了，望采納！
用java將數(shù)據(jù)導出到wps表格中，怎么實現(xiàn)
一:頁面圖片顯示預覽：
1）如下圖：
2）點擊導出按鈕后預覽：
3）最終生成的excel表格圖片預覽：
二：代碼演示：
說明：執(zhí)行操作時，請先引進導出excel表格的jar文件包。
找到導出按鈕所執(zhí)行的js方法，在java后天查看該方法的實現(xiàn)即可。
1）jsp代碼：
