gnuplot 直方图：如何将值放在条形顶部

我有以下数据：

我想使用 gnuplot 生成直方图并将 bar 的值放在其顶部。

这是我尝试创建直方图的 gnuplot 命令：

set style data histogram
set xtics rotate
plot 'file.dat' using 2:xtic(1)

有人能告诉我如何在生成的条形顶部添加值吗？

我找到了以下链接相关的直方图（http://gnuplot-tricks .blogspot.com/2009/10/more-on-histograms.html），但没有明白它到底在做什么。

I have the following data:

I would like to generate histogram using gnuplot and put the value of bar on top of it.

Here is the gnuplot command I tried to create histogram:

set style data histogram
set xtics rotate
plot 'file.dat' using 2:xtic(1)

Can someone tell me how to add values on top of the bars generated?

I found the following link related histogram (http://gnuplot-tricks.blogspot.com/2009/10/more-on-histograms.html), but didnt get what its doing exactly.

使用 0 与 xtic() 配合得很好。

plot 'file.dat' using 2:xtic(1) with histogram, '' using 0:2:2 with labels

using 0 works well with xtic().

plot 'file.dat' using 2:xtic(1) with histogram, '' using 0:2:2 with labels

将此作为示例数据文件 Data.dat：

您可以运行此脚本来显示框及其上方该框的相应值：

set key off
plot 'Data.dat' with boxes fill pattern 1, '' u 1:($2 + 0.5):($2) with labels

注意 u 1:($2 + 0.5)： ($2) 其中 0.5 指定该值高于框的程度。

With this as some sample data file Data.dat:

You could run this script to display boxes and the corresponding value of that box above it:

set key off
plot 'Data.dat' with boxes fill pattern 1, '' u 1:($2 + 0.5):($2) with labels

Notice the u 1:($2 + 0.5):($2) where the 0.5 specifies how much the value is above the box.

假设我有以下 data.dat 文件，

"Method 1"              99.63               9.13                
"Method 2"              97.35               10.85               
"Method 3"              97.16               13.76                        
"Method 4"              95.16               15.56

我可以使用 gnuplot 中的以下命令行获取以下条形图，其值位于条形顶部：

reset

set terminal postscript eps size 3.5,2.62 enhanced color font 'Helvetica,20'  lw 2
set output 'StackOverflow.eps'

set style fill solid 1.00
set style histogram clustered gap 1
set style data histograms
set yrange [0:120] 
set xtics  norangelimit font ",8"
set ytics  norangelimit font ",8"
set xlabel "X-Axis" font "Helvetica,10"
set ylabel "Y-Axis" font "Helvetica,10"
set key font ",8"
set key width -8

xoffset=0.17
yoffset=0.03

plot 'data.dat' using 2:xtic(1) with histogram  title "Parameter 1", \
     '' u 3 with histogram title "Parameter 2", \
     '' u 0:2:2  with labels font "Helvetica,10" offset -0.9,0.5 title " ", \
     '' u 0:3:3  with labels font "Helvetica,10" offset 0.9,0.5 title " "

结果：

条形图，值位于条形顶部

Suppose I have the following data.dat file

"Method 1"              99.63               9.13                
"Method 2"              97.35               10.85               
"Method 3"              97.16               13.76                        
"Method 4"              95.16               15.56

I can get the following bar graph plot with values at the top of the bar with following line of commands in gnuplot:

reset

set terminal postscript eps size 3.5,2.62 enhanced color font 'Helvetica,20'  lw 2
set output 'StackOverflow.eps'

set style fill solid 1.00
set style histogram clustered gap 1
set style data histograms
set yrange [0:120] 
set xtics  norangelimit font ",8"
set ytics  norangelimit font ",8"
set xlabel "X-Axis" font "Helvetica,10"
set ylabel "Y-Axis" font "Helvetica,10"
set key font ",8"
set key width -8

xoffset=0.17
yoffset=0.03

plot 'data.dat' using 2:xtic(1) with histogram  title "Parameter 1", \
     '' u 3 with histogram title "Parameter 2", \
     '' u 0:2:2  with labels font "Helvetica,10" offset -0.9,0.5 title " ", \
     '' u 0:3:3  with labels font "Helvetica,10" offset 0.9,0.5 title " "

Result:

Bar graph Plot with values at top of the bar
