37【源码】数据可视化:基于 Echarts Python 动态实时大屏 - 销售数据看板模板

 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

                                offset: 0,
                                color: "#08808b"
                            },
                            {

                            }
                            ])

                        }
                    }
                },
                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()
