A simple drawing example:

// This chart is an object in JavaScript language. Before using the Chart function, we need to declare an object variable chart to configure the chart.
var chart = {                                           
    // This field marks whether the chart is a general chart. If you are interested, you can change it to false and run it.
    __isStock: true,                                    
    // Zoom tool
    tooltip: {xDateFormat: '%Y-%m-%d %H:%M:%S, %A'},    
    // title
    title : { text : 'Price difference analysis chart'},                       
    // Select range
    rangeSelector: {
