Naming the legend entry in Gnuplot, while plotting from a data file
提问by user1535776
I am plotting a data file with six columns in gnuplot. If the plot of column 2 against column 1 is x(t), I want that line in the legend something like x(t), NOT what I currently get for column two against column one, "trial.dat" u 1:2.
我正在 gnuplot 中绘制一个包含六列的数据文件。如果第 2 列对第 1 列的绘图是 x(t)，我希望图例中的那条线类似于x(t)，而不是我目前从第二列对第一列得到的"trial.dat" u 1:2。
How would I name the legend line, then?
那我该如何命名传奇线呢？

You use the titlekeyword in the plot line:
您title在情节线中使用关键字：
plot 'trial.dat' u 1:2 title "x(t)"
You can also get rid of the legend entry all together by using notitle.
您还可以使用notitle.
