Multiples views of same data

Is there a way to use the same data set in different views with different 
draw-as directives?

I currently gather some basic data on one of our web sites:

datasource latf-login
  ds-source  = "exec:0: /var/bbuser/bin/latfdata %bbdatadir%/%latfdatafile%"
  rrd-ds-type   = GAUGE

datasource latf-follow-link
  ds-source  = "exec:1: /var/bbuser/bin/latfdata %bbdatadir%/%latfdatafile%"
  rrd-ds-type   = GAUGE
  
datasource latf-submit-form
  ds-source     = "exec:2:/var/bbuser/bin/latfdata %bbdatadir%/%latfdatafile%"
  rrd-ds-type   = GAUGE

datasource latf-dl-pdf
  ds-source     = "exec:3:/var/bbuser/bin/latfdata %bbdatadir%/%latfdatafile%"
  rrd-ds-type   = GAUGE

targetType  = latf-times
  ds        = "latf-login, latf-follow-link, latf-submit-form, latf-dl-pdf"
  view      = "latf-performance"

view  latf-performance
    elements = "latf-login latf-follow-link latf-submit-form latf-dl-pdf"

Is there any way to use the same data gathered above but in a different view. 
Specifically I'd like to have one normal line graph and another with the data  
stacked.

Maybe define one datasource in terms of another?
