Selected Test Results (selected in 'Test Results' table below)
What works Data analysis and graphing
What does not
y-axis label is still inverted. (however, in the graph options you can select the "rename" option for the y-axis and set the alignment to 0. then select the label on the graph itself and set the alignment to 270... that seems to work - (everytime you need to work with the label however you need to re-set the alignment to 0.)
You can't select the install options you require (most importantly you can't deselect the excelint.exe install)
NO integration with excel 2007 (or office 2007) - sigmaplot 11 was very unstable and crashed everytime it considered trying to link with office.
What was not tested
Had issues when installing Sigmaplot 11 together with Office 2007, however, it all worked fine when i installed sigmaplot 11 first on a fresh wine install (default: windows 98, use wintricks to install dcom98)...
I then set the default system to winXP and removed the mentioned dlls... i selected the riched20 and ups10.dll's as native... and then installed office 2007.
Leave the default system as winXP but to run sigmaplot set spw.exe to run under win98 and re-select ole32, oleaut32 and rpcrt4.
I don't know why it only worked in that order.. suppose it's got something to do with sigma recognizing an office 2007 install and trying to make the connection...but hey...at least sigma and office are now working at the same time.
