[英]How to plot line in xmgrace using Bash or shell script
我想使用脚本在 xmgrace 中的特定点(例如 2.2)绘制垂直虚线红线
You can either use an external tool such as pygrace or use grace's built-in batch capabilities.您可以使用外部工具(例如pygrace)或使用 grace 的内置批处理功能。 These have been touched upon here on SO before (see, for instance, here or here ).这些之前已经在 SO 上有所涉及(例如,请参阅此处或此处)。
The following script plots a datafile ( exp.dat
) as empty circles, another data file ( line.dat
) as a red dotted line and sets the ranges, labels and major ticks of the two axes:以下脚本将数据文件 ( exp.dat
) 绘制为空圆圈,将另一个数据文件 ( line.dat
) line.dat
为红色虚线,并设置两个轴的范围、标签和主要刻度:
READ NXY "exp.dat"
READ NXY "line.dat"
WORLD XMIN 0
WORLD XMAX 5
WORLD YMIN 1
WORLD YMAX 5
xaxis label "My x label"
xaxis tick major 1
yaxis label "My y label"
yaxis tick major 1
s0 line type 0
s0 symbol 1
s0 symbol size 1.5
s1 linestyle 2
s1 color 2
To generate a vertical red dotted line that passes through 2.2 the contents of line.dat
should be something like要生成通过 2.2 的垂直红色虚线, line.dat
的内容应该类似于
2.2 0
2.2 10000
You can generate such a file in a bash script with the following command:您可以使用以下命令在 bash 脚本中生成这样的文件:
echo "2.2 0\n2.2 10000" > line.dat
Save the script as mybatch.xmg
and call it like this:将脚本保存为mybatch.xmg
并像这样调用它:
xmgrace -batch mybatch.xmg
If you want to directly generate an output you can add this directive:如果要直接生成输出,可以添加以下指令:
PRINT TO "myplot.eps"
DEVICE "EPS" OP "level2"
PRINT
which will save your plot as myplot.eps
(add -nosafe
when calling xmgrace
to get rid of the warnings).这将节省您的情节一样myplot.eps
(添加-nosafe
打电话时xmgrace
摆脱警告)。
