edit :

i go to install gunplot then compile it but i got same result.

the file f1.pgf-plot its ok but where mistake?

Because there are many mikstakes. Package pgf Warning: Plot data file a97052aa-662f-46da-ba1b-6eab1e38a7a9.pgf-plot.table not found. (for example). — Sebastiano, Nov 03 '23 at 21:31
Welcome. Did you follow the instructions of the comment in your picture? Is gnuplot installed? Is LaTeX run with shell escape active? Does gnuplot return a result? — Qrrbrbirlbel, Nov 03 '23 at 21:36
yes i was compile it but i cant solve this ! Package pgf Warning: Plot data file `f1.pgf-plot.table' not found. — Ellen Ellen, Nov 03 '23 at 21:46
Remove all auxiliary files(only have your file (f1.tex) in the folder). Compile. Now does f1.pgf-plot.table exist? Carefully read all errors and warnings. Ask about these errors and warnings here, if you do not understand them. As it is now, it is not possible to help. — hpekristiansen, Nov 04 '23 at 00:14

In the f1.tex, you have 7 functions without id, there will only be one table created by Gnuplot (the last). You therefore need an identifier per function.

[parametric,id=pgf-plot1] for the first function

[parametric,id=pgf-plot2] for the second function...

After the first compilation there are only axes in the pdf and 7 warnings.

f1.pgf-plot1.table not found...

but 7 files were created in the folder.

You must open each of these files with gnuplot to create the .table files

A second compilation pdflatex and...

You can also compile with the option shell-escape or enable-write18 see the pgfmanual documentation section 22.6 Plotting a Function Using Gnuplot — pascal974, Nov 04 '23 at 12:48
