我想使用GNUPlot生成,这是一个来自y轴值列表的2d图,没有明确说明相应的x值。换句话说,我没有
x y
1 5
2 3
3 5
4 6
5 14
但是
5 10 3 5 6 14 (y-values listed only, not x values)
如何通过仅指定x的边界来生成二维图,假设是均匀间距,而不是明确列出x?
然后我想插入y值
答案 0 :(得分:2)
您可以使用M:\>tnsping xe

伪列:
0
为了从1开始计数,下面的示例使用 column(0) The sequential order of each point within a data set.
The counter starts at 0 and is reset by two sequential blank
records. The shorthand form $0 is available.
。如果需要,更通用的表单为($0+1)
,其中$0*step + xMin
表示xMin
所需的最小值,x
表示步长(单个x值的间距)
step
