ViVa waveform Radix control

hello export, we run simulation by Ocean script and picked specific signals to be plotted. what we noticed is when ViVa displays digital bus signals (e.g., by plot(getData("/cmd_ascii[31:0]") ?expr '("CMD_ASCII"))) , seems it always display Hex value until we manually pick the Radix to Decimal or Ascii, etc. is there a way for me to specify it to display in Decimal / Ascii directly instead of manual picking every time? default display: after manually pick the desired Radix: thanks, David IC6.1.7-64b.500.9
