调整多色图中每个绘图的比例以均匀分布
我正在尝试使用gnuplot中的“multiplot”选项绘制多个图形。 我的情节如下图所示。
我有一个小问题，但我不知道如何解决这个问题。问题在于每个单独情节的规模。如果一个通知，每个图a，b，c，d和e的比例是不同的。对于每个绘图，我使用了不同的set xrange值。所以，我理解gnuplot试图拉伸图以适应给定的宽度限制。因此，沿水平轴的刻度不均匀间隔。
我希望每个绘图的刻度均匀分布，尤其是水平轴。
下面我给出了您的观点的完整代码。
我如何完成这项工作？
非常感谢提前。

1 个答案:
答案 0 :(得分：3)
如果我理解正确，您希望所有图表的单位长度相同。您可以使用do循环动态设置边距以获得此效果。基本上你需要在开头和你将找到的最大范围内定义xranges（你也可以通过更多的工作自动完成）。以下代码应该按照您的要求执行（阅读注释以获取更多信息）：
# This function returns the ranges for each graph,
# I have only defined 3
range(i)=(i == 1 ? "-20 20" : \
i == 2 ? "-25 25" : \
i == 3 ? "-15 15" : 1/0)
# Number of graphs and maxrange
N = 3; maxrange = 50.
set xtics 5.
set multiplot
# Loop
do for [i=1:N] {
# Set the margins
set tmargin at screen 0.98-(i-1.)/N
set bmargin at screen 0.74-(i-1.)/N
# Set range and calculate total range for graph i
set xrange [word(range(i),1) : word(range(i),2)]
totalrange = word(range(i),2) - word(range(i),1)
# Center the graphs at 0.55 and scale them depending on their range
set lmargin at screen 0.55-0.43*totalrange/maxrange
set rmargin at screen 0.55+0.43*totalrange/maxrange
# Plot
plot sin(x) not
}
当然，这里有足够的定制空间。
您还可以根据标签i定义您的功能，以便它们通过循环进行更改：
f(x,i) = (i == 1 ? sin(x) : \
i == 2 ? cos(x) : \
i == 3 ? tan(x) : 1/0)
.
.
.
plot f(x,i)
如果您有数据文件，可以这样做：
datafiles = "data1 data2 data3"
.
.
.
plot word(datafiles,i)
同样的风格等：
set style line 1 lw 1
set style line 2 lw 2
set style line 3 lw 3
.
.
.
plot f(x,i) ls i
最后，如果你想要完全控制（例如你正在混合函数和数据文件或其他东西），你可以在for循环中定义if语句：
.
.
.
if (i == 1) {plot sin(x)}
if (i == 2) {plot cos(x)}
if (i == 3) {plot "data1"}
