echarts 折线图。需要引入：echarts.min.js
<script src="${ctxStatic}/common/echarts.min.js" charset="utf-8" type="text/javascript"></script>
JS调用后台方法，得到数据
Map<String, Object> map = new HashMap<String, Object>();
for (Integer i = 0; i < 24; i++) {
boolean isExit = false;
String fixIndex = "";
if (i < 10) {
fixIndex = "0" + i;
} else {
fixIndex = i.toString();
}
for (Map<String, Object> spMap : list) {
String hour = spMap.get("hour_remark").toString().substring(11);
if (hour.equals(fixIndex)) {
failcount.add(Integer.valueOf(spMap.get("fail_count").toString()));
isExit = true;
continue;
}
}
if (!isExit) {
failcount.add(0);
}
}
Map<String, Object> failcountmap = new HashMap<String, Object>();
failcountmap.put("name", "失败数量");
failcountmap.put("data", failcount);
allInfo.add(failcountmap);
map.put("data", allInfo);
