Highcharts选项覆盖问题

是指在使用Highcharts图表库时,当设置多个选项时,后面的选项会覆盖前面的选项,导致前面设置的选项无效的问题。

为了解决这个问题,可以采用以下两种方法:

  1. 使用extend函数:Highcharts提供了一个extend函数,可以用来合并多个选项。通过将要合并的选项对象作为参数传递给extend函数,可以将多个选项合并为一个选项对象,确保所有选项都生效。例如:
代码语言:txt
复制
var options1 = {
    chart: {
        type: 'line'
    },
    title: {
        text: 'Chart Title'
    }
};

var options2 = {
    xAxis: {
        categories: ['A', 'B', 'C']
    },
    title: {
        text: 'X Axis Title'
    }
};

var mergedOptions = Highcharts.extend(options1, options2);
  1. 使用jQuery的extend函数:如果项目中已经引入了jQuery库,可以使用jQuery的extend函数来合并选项。与Highcharts的extend函数类似,通过将要合并的选项对象作为参数传递给jQuery的extend函数,可以将多个选项合并为一个选项对象。例如:
代码语言:txt
复制
var options1 = {
    chart: {
        type: 'line'
    },
    title: {
        text: 'Chart Title'
    }
};

var options2 = {
    xAxis: {
        categories: ['A', 'B', 'C']
    },
    title: {
        text: 'X Axis Title'
    }
};

var mergedOptions = $.extend(true, {}, options1, options2);

以上两种方法都可以解决Highcharts选项覆盖问题,确保所有选项都能生效。

    zigbee物联网开发平台(工业物联网)

    1.概述 鉴于ZigBee技术适合用于数据采集系统的的特点, 提出了基于ZigBee的数据采集系统的设计方案, 着重探讨ZigBee节点的硬件设计及其组网设计. 并详细讨论了基于CC2530芯片的数据采集节点的硬件设计方案, 组网设计中的协调器建立网络、节点加入网络的设计方法, 以及数据采集系统的软件设计方法. 最后通过采集ZigBee网络传感器数据的实验, 证明该方案能取得良好的通信效果. 1.1 系统描述 利用ZigBee传感器网络、网关、服务器实现简单的数据采集系统。项目中把使用了三种传感器,分别是:温湿度传感器,烟雾传感器,光敏传感器。终端节点传感器采集到数据之后发送给协调器之后,由协调器通过串口将数据发至给电脑客户端,最后电脑客户端将串口发送上来的传感器数据使用套接字封装成http格式后通过post方式发送到服务端,并且存储到数据库中。客户端通过访问服务器,获取数据展示出来。 1.2 系统结构介绍
