IDL之用超粗线代替柱状图不可取

15195775117

问题起源：
因为制作比例型柱状图，绘图采用覆盖式画法（可查看IDL的barplot的help），我感觉比较麻烦，
于是想能否用超粗线代替之，
而试验证明，线条的宽度有限制，好像最大只能是10，比柱子的宽度要求低很多，
所以，此想法失败
fig=plot(indgen(10),thick=2,/current,layout=[4,2,1])
fig=plot(indgen(10),thick=4,/current,layout=[4,2,2])
fig=plot(indgen(10),thick=6,/current,layout=[4,2,3])
fig=plot(indgen(10),thick=8,/current,layout=[4,2,4])
fig=plot(indgen(10),thick=10,/current,layout=[4,2,5])
fig=plot(indgen(10),thick=15,/current,layout=[4,2,6])
fig=plot(indgen(10),thick=20,/current,layout=[4,2,7])
fig=plot(indgen(10),thick=30,/current,layout=[4,2,8])

fig=barplot(indgen(10))
fig=barplot(indgen(10)/2.0,fill_color='r',/overplot)
