Xmgrace设置：如何在2D绘图arg文件中添加命令设置Y轴范围

Got it, let's fix that annoying empty space at the top of your Y-axis! To manually lock in the exact Y-axis range you need (0 to 12, matching your data), you just need to add two simple commands to your .arg file:

• Use @ yaxis min <value> to define the lower bound of the Y-axis
• Use @ yaxis max <value> to define the upper bound of the Y-axis

For your specific case, you'll add @ yaxis min 0 and @ yaxis max 12 to override Xmgrace's default auto-scaled range. Here's what your modified .arg file will look like (I also formatted the data lines for readability):

@ title "title"
@ xaxis label "Frame"
@ yaxis label "Number of hits"
@ yaxis min 0
@ yaxis max 12
@TYPE xy
0 0
1 1
2 3
3 8
4 7
5 8
6 8
7 8
8 8
9 12

By default, Xmgrace adds extra padding to axis ranges automatically, which is why you were seeing a Y-axis max of 40 even though your data only goes up to 12. These two commands force the axis to fit exactly your data's range, eliminating that empty upper space.
