Gnuplot program is not working


when I want to plot the result I got this message

The Gnuplot program is not responding. please ensure that the path is correct or the program exists.

thank you

Dear @AHMAD,

Let me first remark that your post does not contain any question.
Secondly, the error message is pretty straightforward: is gnuplot installed on your machine? Is the correct path to gnuplot specified in the flair’s preferences (Flair Tab → Config → Preferences → Gnuplot)?
