如何在Gnuplot中显示堆叠的条形图？ [英] How to display a stacked barchart in Gnuplot?

问题描述

我有一个看起来像这样的数据文件：

I have a data file that looks a bit like this:

A 0.2  0.5
B 0.65 0.8
C 0.4  0.2

即，它包含三列，第一列包含标签，另一列两列浮点值。列用空格隔开。

i.e., it contains three columns where the first column contains labels and the other two columns float values. Columns are separated by spaces.

我想以这样的方式绘制此图，即标签在X轴上显示为tic，而列则绘制为两个不同的图

I'd like to plot this in a way that the labels appear as tics on the x-axis while the columns are plotted as two differently colored barcharts on top of each other.

如何使用Gnuplot实现此目的？

How can I achieve this using Gnuplot?

推荐答案

假设您的数据存储在文件 1.dat 中，则可能会生成堆叠的条形图，如下所示：

Assuming your data are stored in the file 1.dat, stacked barcharts might be generated as follows:

set style data histograms
set style histogram rowstacked
set boxwidth 1 relative
set style fill solid 1.0 border -1
set yrange [0:1.5]
set datafile separator " "
plot '1.dat' using 2 t "Var 1", '' using 3:xticlabels(1) t "Var 2"

如您所见，条形图与直方图没​​有区别（至少在Gnuplot内部）。可以在gnuplot 演示页面上找到更多信息。

As you can see, barcharts are no different from histograms (at least, from within Gnuplot). More information can be found on gnuplot demo page.
