Thanks that was just the help I needed. I realized I could put the
charting code at a different location pointed to here in frame, i.e.
class SpectrumResults(webapp.RequestHandler):
def post(self):
self.response.out.write('<iframe src=SpectrumChart width="600"
height="400"></iframe>')
class SpectrumChart(webapp.RequestHandler):
def get(self):
mytitle ='"Hello World"'
mydata='t:40,20,50,20,100|80,80,80,80,80'
template_values = {'mytitle': mytitle,
'mydata': mydata}
path = os.path.join(os.path.dirname(__file__), "index.html")
self.response.out.write(template.render(path,
template_values))
