gnuplot：在右上角的框中包含模拟参数

我是gnuplot的新手。有人能告诉我如何在绘图右上角的方框中包含模拟参数吗？我希望参数框在用于显示实际曲线的图例下方可见

我只想包括表单的三个参数：

"GraphConnectivity: 0.2"
"Query: 0.2"
"Content: 0.2"

---

应该在图例下方的框中可见。

要添加标签，您需要

设置标签

e、 g

你需要和XVAL和YVAL玩一玩，让标签显示在你想要的地方

或者，可以使用3个“设置标签”命令：

set label "GraphConnectivity: 0.2" at screen XVAL, screen YVAL
set label "Query: 0.2" at screen XVAL, screen YVAL offset character 0,-1
set label "Content: 0.2" at screen XVAL, screen YVAL offset character 0,-2

---

要在标签周围放置一个框，可以使用无头箭头，也可以使用

设置对象矩形

命令

要在标签周围放置一个框，可以使用无头箭头，也可以使用

set object rectangle

命令将标签放置在框中的方法非常好（在gnuplot 4.2+中）

若要查看这将如何处理标签中的多行，请尝试将下面的行从链接复制并替换到示例中：

#
# Illustrate using character widths to put a box around a label
#

# each line of the label gets a separate variable here
label1 = "Label in"
label2 = "a box"
label3 = "rocks"
LABEL = label1."\n".label2."\n".label3
# this bit finds the longest part of the multi-line string
# to determine the box width
longlabel = (strlen(label1) > strlen(label2)) ? label1 : label2
longlabel = (strlen(longlabel) > strlen(label3)) ? longlabel : label3

# change 'char 2' below to reflect the number of lines in the label.
# you will also have to adjust the y-position of the rectangle manually
set obj 10 rect at -3,(-4-0.4) size char strlen(longlabel), char 3
set obj 10 fillstyle empty border -1 front
set label 10 at -3,-4 LABEL front center

在gnuplot 4.2+中，有一种很好的将标签放在盒子中的方法

若要查看这将如何处理标签中的多行，请尝试将下面的行从链接复制并替换到示例中：

#
# Illustrate using character widths to put a box around a label
#

# each line of the label gets a separate variable here
label1 = "Label in"
label2 = "a box"
label3 = "rocks"
LABEL = label1."\n".label2."\n".label3
# this bit finds the longest part of the multi-line string
# to determine the box width
longlabel = (strlen(label1) > strlen(label2)) ? label1 : label2
longlabel = (strlen(longlabel) > strlen(label3)) ? longlabel : label3

# change 'char 2' below to reflect the number of lines in the label.
# you will also have to adjust the y-position of the rectangle manually
set obj 10 rect at -3,(-4-0.4) size char strlen(longlabel), char 3
set obj 10 fillstyle empty border -1 front
set label 10 at -3,-4 LABEL front center
