Gnuplot 在基于时间的线图上绘制布尔值

我正在绘制一个基于时间的折线图，并希望向其中添加一个布尔数据系列

是否可以让布尔数据突出显示值为真的图形画布的整个高度

打印文件：

set datafile separator ","
set terminal pngcairo size 800,400
set title "Solar charge monitor"
set yrange [0:]
set ylabel "V"
set y2range [0:]
set y2label "A"
set y2tics
set xlabel "Date"
set xdata time
set timefmt "%Y-%m-%dT%H:%M:%SZ"
set key left top
set grid
set output "samplePlot.png"
plot "sampleData.csv" using 1:2 with lines lw 2 title 'Batt (V)', \
     "sampleData.csv" using 1:3 with lines lw 2 title 'Solar (V)', \
     "sampleData.csv" using 1:4 with lines lw 2 title 'Charge (A)' axes x1y2, \
     "sampleData.csv" using 1:5 with lines lw 2 title 'Load (A)' axes x1y2

样本数据：

我想添加第6列，它是一个布尔值（0/1）。在此示例数据中，背景将被完全高亮显示，因为布尔值始终为真

---

任何提示？

根据第6列的值，您可以使用

框打印样式绘制背景框，例如

plot "sampleData.csv" using 1:($6 * 16) with boxes fc rgb '#ccffcc' fillstyle solid,\
     "" using 1:2 lt 1 with lines lw 2 title 'Batt (V)'

但是，这要求您知道y范围的最大值和最小值。如果该值应自动计算，则首先需要使用
未知
终端绘制虚拟图，然后使用
GPVAL\u Y\u MIN
和
GPVAL\u Y\u MAX
：

reset
set datafile separator ","
set terminal pngcairo size 800,400
set title "Solar charge monitor"
set yrange [0:]
set ylabel "V"
set y2range [0:]
set y2label "A"
set y2tics
set xlabel "Date"
set xdata time
set timefmt "%Y-%m-%dT%H:%M:%SZ"
set key left center
set grid
set autoscale xfix
set style data lines

set terminal push
set terminal unknown
plot "sampleData.csv" using 1:2, "" using 1:3
set terminal pop

set output "samplePlot.png"
plot "sampleData.csv" using 1:(GPVAL_Y_MIN + $6 * (GPVAL_Y_MAX - GPVAL_Y_MIN)) with boxes fc rgb '#ccffcc' fillstyle solid notitle,\
     "" using 1:2 lt 1 lw 2 title 'Batt (V)', \
     "" using 1:3 lt 2 lw 2 title 'Solar (V)', \
     "" using 1:4 lt 3 lw 2 title 'Charge (A)' axes x1y2, \
     "" using 1:5 lt 4 lw 2 title 'Load (A)' axes x1y2

使用稍微更改的数据文件（我插入了一些零以显示效果），我得到：


如果不希望在边界处使用垂直线，也可以使用
填充曲线
：

...
plot "sampleData.csv" using 1:(GPVAL_Y_MIN + $6 * (GPVAL_Y_MAX - GPVAL_Y_MIN)) with filledcurves x1 fc rgb '#ccffcc' fillstyle solid notitle,
...

最好在此处包含您的数据样本，并将脚本减少到问题所需的最低限度。当你说“突出”时，你到底是什么意思？
