减少绘图中的空白空间并使图形最佳拟合
我正在使用11个图绘制多重绘图。我给出了下面使用的代码：

我得到的图表显示在
我从图中注意到图表之间有很多空白区域。例如，图（a）和（b）之间以及图（a）和（d）之间。我想减少它们之间的空间，使图形更大。
我应该做些什么来减少空间并优化图表大小。
提前致谢。
1 个答案:
答案 0 :(得分：1)
好的，让我们开始：）
首先，您的脚本和数据文件的命名非常适合迭代。因此，您可以使用占位符%s定义文件名模板列表，该占位符稍后将替换为实际参数。
因此，您首先对不同的O11，O12等值进行迭代，并为每个值生成一个新的图。然后，您对文件名进行plot for次迭代，这些文件名都放在一个图中。
使用set linetype定义颜色可以使用自动线型增量。
现在问你的实际问题：
我认为最好的选择是稍微纠正标签的偏移，例如与
set ylabel "g(r)" offset 1,0 @labelFONT
将ylabel相对于自动选择的位置向右移动一个字符单元。这应该会给你一个更大的图表。
如果这还不够，您必须开始手动设置边距。我首先只改变顶部和右边距。例如。
set tmargin 0
set rmargin 0
顶部和右边距将放置在相应面板的边界处。用例如set rmargin 0.5右边距设置为半字符宽度。你必须使用这些值。
这是一个缩短的脚本。请注意，我无法测试它，因为我没有数据文件。我希望我没有犯错误:)）
