A tool to visualize real time numerical data as a line chart
This tool is currently a work-in-progress and may drastically change in the future.
Launch it:
shell
popoplot --bind 127.0.0.1:9999 --bar-capacity 50 --max 100 --min 0
Feed it with some data. Here we are sending to its tcp port a stream of numbers from 0 to 100 and back using netcat.
shell
s=1;
k=1;
while sleep 0.1; do
echo $k;
let k=$k+$s;
if [ $k -eq 100 ]; then
s=-1;
elif [ $k -eq 0 ]; then
s=1;
fi;
done | nc localhost 9999
This is the output:
