我有一个json文件:
{
"challenge0" : [
{
"X" : "-15.5820999145508",
"time" : "1489079614.50596",
"Speed" : "Optional(__C.CGVector(dx: 0.0, dy: 0.0))",
"Y" : "-10.6790924072266"
},
{
"X" : "-15.5820999145508",
"time" : "1489079615.39075",
"Speed" : "Optional(__C.CGVector(dx: 3.3732881377091e-08, dy: 5.58793544769287e-07))",
"Y" : "-10.6790924072266"
},
{
"X" : "-15.5917558670044",
"time" : "1489079615.40559",
"Speed" : "Optional(__C.CGVector(dx: -0.772350311279297, dy: 2.60296104670488e-07))",

},
{
"X" : "-15.6142683029175",
"time" : "1489079615.42163",
"Speed" : "Optional(__C.CGVector(dx: -1.54341471195221, dy: 2.79396772384644e-07))",
"Y" : "-10.6790924072266"
},
"challenge1Time" : "2.24",
"challenge4Time" : "9.98",
"TotalTime" : 24.17413234710693,
"challenge0Time" : "1.52"
如何在一个情节中绘制挑战时代?
我的意思是,我想要一个包含2个维度的图表:
x: Challenge times
y: Time
我正在使用Rstudio。
