在Gnuplot中绘制新冠病毒-19数据

我试图绘制（GNUPlot）CSV文件中包含的一些数据，该文件使用第一行作为时间数据，并在每列中对应案例计数。我想为每一个州（每一行）绘制一个单独的图，但运气不太好。有什么帮助吗？到目前为止，这就是我的情节脚本。我在脚本中使用[col=5:30:1]的

plot…

，因为前4列是州名称和地理位置。我想我现在应该专注于数据点，并最终找出如何在绘图上显示州名称。我已将美国数据从主要CSV数据中grep出来，以创建“us.dat”：

以及“us.dat”文件的一小部分：

但是，绘图图像不太正确：

一种可能的解决方案是使用awk。 通过使用它，您可以转换文件并正常使用gnuplot（也要感谢这个令人惊讶的答案：） 您甚至可以在gnuplot内部进行内联操作

华盛顿可以按如下方式进行策划

set xdata time
set timefmt "%m/%d/%y"
pl "<awk -F, '{ for (i=5; i<=NF; i++)  { a[NR,i] = $i} } NF>p { p = NF } END { for(j=5; j<=p; j++) {str=a[1,j];for(i=2; i<=NR; i++){str=str\" \"a[i,j];}print str}}' us.dat" using 1:2 w l title "Washington"

设置扩展数据时间
设置时间表“%m/%d/%y”
pl“
这里是一个纯gnuplot版本
