这些代码是用javascript编写的，并使用下面的hightChart StockChart。
程序可以通过stockChart中的datetime和report_value1绘制图表，并在工具提示中显示report_value1。
我想添加更多值，以便在工具提示的pointFormat中显示。
如何添加代码以显示工具提示中speed_data的rpm值？
var speed_data = [];
for (var i = 0; i < _datalenght; i++) {
v = sData[i];
speed_data.push([
v.report_time * 1000,
v.report_value1,
v.rpm,
]);
}

我努力地尝试。
