设置网格x，但不在00：00：00.000

Question

我想知道是否可以设置网格x，但是它不能在时间00：00：00.000开始

set grid x layerdefault front
set xtics nomirror
set ytics nomirror
set xdata time
set timefmt "%H:%M:%S"
set format x "%H:%M:%.3S"
set xrange ["00:00:00.000":maxtime]

Answer 1

可以将网格设置为使用任何或所有x标记（标记的标记），mxtics（“次要”标记，未标记的标记），x2标记（辅助轴在顶部）或mx2tics（次要标记在辅助轴上。对于绘图例如您显示的那个，一种选择是关闭xtics并沿着x2设置tic，从而将tic忽略为零。

... everything as before, then add ...
set x2data time      # configure secondary axis to match primary axis
set link x2          # same range and scale on both primary and secondary x axis
set grid nox x2      # set xtics off, x2tics on
set x2tics 30., 30.  # tics every 30 seconds starting at 30 seconds
set x2tics format "" # don't label the x2 tics
