xplot binary package in Ubuntu Noble riscv64

 XPlot is a small program to plot one- or two-dimensional datasets, which are
 present either in a file or are generated `on-the-fly' and piped to XPlot.
 XPlot lets you display one or more datasets and lets you zoom to different
 sections of the sets. Also. `blowups' of the currently shown portion of the
 data can be made.
 .
 XPlot is meant for on-screen data exploration. It does not have a print
 button, nor is it meant for final output or publication-quality figures.
