Re: tickmark help with bar chart

Hi Erik,
I would expect the following to work:
sres@tmXBMode = "Explicit"
sres@tmXBValues = ispan(1,32,1)
sres@tmXBLabels = "E"+sres@tmXBValues

In this case you will need to set tmXBMode = "Explicit", as you want
customized XB labeling and you want major tick marks at every instance
of your x-array. Let us know if the above doesn't help.. Adam
