如何在侏儒图中关闭y轴？

Question

我的目标是关闭我的阴谋的y轴。抽搐被放置在边界上，我希望在情节开始之前有一个小的缺口。"unset yzeroaxis“不知何故什么也做不了。

另一个问题是，我如何将x轴的数字对齐？现在，他们似乎是左对齐。

代码和输出如下。不要介意这些轴，函数只是示例，并且为以后将读取的数据做好了缩放准备。

mpl_top    = 0.4 #inch  outer top margin, title goes here

mpl_right  = 0.1 #inch  outer right margin, y2 label goes here
mpl_height = 1.5 #inch  height of individual plots

xsize = mpl_left+mpl_right+(mpl_width*mpl_nx)+(mpl_nx-1)*mpl_dx
ysize = mpl_top+mpl_bot+(mpl_ny*mpl_height)+(mpl_ny-1)*mpl_dy

# placement functions
#   rows are numbered from bottom to top
bot(n) = (mpl_bot+(n-1)*mpl_height+(n-1)*mpl_dy)/ysize
top(n)  = 1-((mpl_top+(mpl_ny-n)*(mpl_height+mpl_dy))/ysize)
#   columns are numbered from left to right
left(n) = (mpl_left+(n-1)*mpl_width+(n-1)*mpl_dx)/xsize
right(n)  = 1-((mpl_right+(mpl_nx-n)*(mpl_width+mpl_dx))/xsize)

Answer 1

您正在显式设置多次：

set arrow 1 from graph 0, first 0 rto graph 1,0 nohead lt 1 lw 1 lc 0
set arrow 2 from first 0, graph 0 rto 0, graph 1 nohead lt 1 lw 1 lc 0

它基本上就是一个y零轴和一个xzeroaxis。只要去掉这些线就行了。

即使您为第一个子图注释掉了这些行，如果您再次从控制台启动代码，除非您用一行reset session启动脚本，否则箭头、标签和对象也将是持久的。

xtics center行应该这样做。否则，您可以选择offset。检查help xtics。

顺便说一句，一旦你设置了一个范围或另一个设置，它将被保留为下一个(子)图。您需要多次指定相同的内容。你的代码可以大大缩短。
