rsimmons gave a good answer. You can also change that by going to Settings --> Searches, reports and alerts
choose the report and go to Advanced Edit display.visualizations.show and change the value to "0"
Hi @anwarmmian can be the setting of display.visualizations.show = 0 in GUI overruled by different setting?
I have the value set to 0 and I am still getting the chart at the top of pdf send by sendemail command.
Thank you for help.
