i am having trouble getting the second axis in my chart to update.
i am parsing xml-data into a chart.
the client needs more than one feed displayed, so I supply a combobox.
but when i switch from xml with larger numbers to an xml-feed with a
smaller, the second axis retains it's scale.
where as the first adopts beautifully to similar changes.
example xml_1: (2,100),(3,250),(4,900)
xml_2: (2,100000),(3,105005),(4,231111)
switch first from xml_1 to xml_2 gives an okay scale.
from xml_2 back to xml_1 the second axis retains it's scale.
why is this a problem. because with that scale the xml_1 line then
becomes an almost straight line.
belows's the code i am using. (abbreviated - but just to give an
expression)ยด
hope somebody can help me out.
but this seems like a bug to me.
