Graphs with no data

[pferguson83]

Having a bit of bother trying to see any data on the graphs. Is there any debug mechanism so that i can see what is tripping the plugin?
Could you please clarify what is required for the Utilization Report Path and the file within? I am using vivado 2021.1

I am using the following command from vivado
report_utilization -file [file join $REPORT_DIR utilization_report.rpt]

Can you also advise how i would plot the results from:

report_timing_summary -file [file join $REPORT_DIR timing_report.rpt]
report_power -file [file join $REPORT_DIR power_report.rpt]
report_io -file [file join $REPORT_DIR io_report.rpt] -format text -name io_report
