我正在绘制一个地区的降雨图。我的问题是,当温度高于既定刻度时,会绘制一些白点。
功能:
spplot(
datavalue,
main = list(label=main,cex=0.9),
sp.layout = layout.list.compl(shapeBound,shapeSurround,complete=TRUE,0.45),
xlim = xlim,
ylim = ylim,
col.regions = color,
at = c(0,10,20,30,50,70,90,110,130,150,170,190,210,230),
colorkey = list(
labels=list(
at = labelat,
labels = c("0","10","20","30","50","70","90","110","130","150","170","190","210","230")
)
),
scales = list(draw=TRUE),
pretty = TRUE,
cex = 10
)
spplot 函数中是否存在某种动态范围?
