如何在Corona SDK中绘制折线图

local widget = require("widget")
local composer = require("composer")
local chartwidget = require("chartwidget")

local scene = composer.newScene()

local data = {10, 20, 30, 40, 50, 60} -- 折线图数据
local chartOptions = {
    xLabels = {"Jan", "Feb", "Mar", "Apr", "May", "Jun"}, -- x轴标签
    yMax = 70, -- y轴最大值
    yMin = 0, -- y轴最小值
    showXLabels = true, -- 是否显示x轴标签
    showYLabels = true, -- 是否显示y轴标签
    showYGrid = true, -- 是否显示y轴网格线
    showLegend = true -- 是否显示图例
}

local lineChart = chartwidget.newLineChart{
    left = display.contentCenterX - 150,
    top = display.contentCenterY - 150,
    width = 300,
    height = 300
}

lineChart:setData(data, chartOptions)
lineChart:setLineStyle(2, {0, 0.4, 0.7}) -- 设置折线样式

scene.view:insert(lineChart)
