效果图展示
1.动态效果演示
2.静态切片效果图
一、确定需求方案
1.确定产品上线部署的屏幕LED分辨率
本案例基于16:9 屏宽比,F11全屏显示。
2.部署方式
浏览器打开播放,Chrome浏览器、360浏览器等。
二、整体架构设计
前端基于 Echarts开源库设计,使用WebStorm编辑器;
后端基于Python Flask实现,使用 Vscode 或 Pycharm编辑器;
数据传输格式:JSON;
数据源类型:目前采用JSON文件方式,可自行添加支持PostgreSQL、MySQL、Oracle、Microsoft SQL Server、SQLite,自行添加pandas支持Excel表格等,还可以定制HTTP API接口方式。
数据更新方式:采用http get 轮询方式 。在实际应用中,也可以视情况选择j监测后端数据实时更新,实时推送到前端的方式;
三、编码实现 (关键代码)
1.前端html代码

2. 前端JS - echarts 折线图
// 折线图
function lineChart(ele) {
var chart = echarts.init(document.querySelector(ele));
var xdata = [];
var dataArr = [];
for (var i = 1; i < 30; i++) {
xdata.push(i);
dataArr.push(Math.floor(Math.random() * 20 + 5))
}
var max = Math.max.apply(null, dataArr);
var seriesName = '';
option = {
grid: {
left: "5%",
// right: "2%",
bottom: "5%",
top: "15%",
containLabel: true
},
xAxis: {
type: "category",
data: xdata,
axisLabel: {
show: true,
textStyle: {
color: "#fff",
fontSize: 0.5 * w
}
},
axisLine: {
lineStyle: {
color: 'transparent',
width: 2 //这里是为了突出显示加上的
}
}
},
tooltip: {
show: true,
trigger: 'item'
},
yAxis: [{
type: 'value',
// name: '立方米',
min: 0,
max: 25,
axisLabel: {
formatter: '{value}k',
textStyle: {
color: '#fff',
fontSize: 0.5 * w
}
},
axisLine: {
lineStyle: {
color: 'transparent',
width: 2 //这里是为了突出显示加上的
}
},
axisTick: {
show: false,
},
splitLine: {
show: false
}
}],
series: [{
name: seriesName,
type: 'line',
stack: '总量',
symbol: 'none',
smooth: false,
symbol: "circle",
itemStyle: {
normal: {
color: '#34a39a',
lineStyle: {
color: "#34a39a",
width: 2
},
areaStyle: {
//color: '#94C9EC'
color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{
offset: 0,
color: "#08808b"
},
{
offset: 1,
color: 'rgba(0,0,0,0.2)',
}
])
}
}
},
data: dataArr
},]
};
var index = 0; //播放所在下标
var mTime = setInterval(function () {
chart.dispatchAction({
type: 'showTip',
seriesIndex: 0,
dataIndex: index
});
index++;
if (index > xdata.length) {
index = 0;
}
}, 1500);
chart.setOption(option)
}
lineChart('.lineChart')
3. 前端JS - 数据定时更新控制
支持在每个echarts图表中独立控制定时更新的间隔。
var init = function () {
updating();
setInterval(function() {updating()}, 2000);//刷新周期设置
};
4. 后端 Python Flask 代码
@app.route('/get_percent')
def get_percent():
jsonData = {}
jsonData['percent1'] = random.randint(0, 100)
jsonData['percent2'] = random.randint(0, 100)
jsonData['percent3'] = random.randint(0, 100)
jsonData['percent4'] = random.randint(0, 100)
return json.dumps(jsonData)
def loop():
time.sleep(10)
pass
# 主程序在这里
if __name__ == "__main__":
a = threading.Thread(target=loop)
a.start()
# 开启 flask 服务
app.run(host='127.0.0.1', port=80, debug=True)
