plot 3d graph from randrw benchmark

hi, I run following bench_fio command:

I can't figure out how to plot a 3D graph from the data, the command just fails, example what I've tried:

$ ~/fio-plot/fio_plot/fio_plot -i ./nfstest/randrw80/4k/ -T "rhel84 lvm linear" -d 1 2 4 8 16 32 64 -n 2 4 8 16 32 64 -L -t iops -r randrw
Since we are processing randrw data, you must specify a filter for either read or write data, not both.

$ ~/fio-plot/fio_plot/fio_plot -i ./nfstest/randrw80/4k/ -T "rhel84 lvm linear" -d 1 2 4 8 16 32 64 -n 2 4 8 16 32 64 -L -t iops -r write     
Could not find any (matching) JSON files in the specified directory /home/azureuser/nfstest/randrw80/4k

Are the correct directories specified?

If so, please check the -d ([1, 2, 4, 8, 16, 32, 64]) -n ([2, 4, 8, 16, 32, 64]) and -r (write) parameters.

thank you for any hint.

You may need to specify a 'filter' parameter -f read or -f write

Please also note tha tnumbjobs in your benchmark run only goes to 32 whereas you do specify 64 which would explain the second error.

I'm assuming this issue is resolved.
