Greetings! I just started using the API and I love it. Totally awesome. I really appreciate all the work that's been done and hope to be able to contribute some back in the near future.
I work in Rails and picked up the GC4R plugin. Again, awesome. I've added rotation to the 3D pie chart and a separate parameter for labels vs. legends. I don't know the author and I haven't found any way to contact him to see if he's taking contributions. If he's here or anyone knows how to contact him I'd appreciate being put in contact. I'm at bwalton dot im at gmail dot com. Now on to the primary reason for my email. Perhaps it's a feature that I just haven't found documented, but past a certain 'threshold' the slices in a 3D pie chart stop rendering properly; that is, in correct proportion. Using one of the examples from the documentation... The original renders proportions correctly: http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World Adding a third parameter renders proportions correctly: http://chart.apis.google.com/chart?cht=p3&chd=t:60,40,100&chs=250x100&chl=Hello|World Increasing the value of the third parameter renders proportions incorrectly: http://chart.apis.google.com/chart?cht=p3&chd=t:60,40,110&chs=250x100&chl=Hello|World It appears to me that the threshold is a function of the total of the parameters. Divide each by 10 and the proportions are rendered correctly. http://chart.apis.google.com/chart?cht=p3&chd=t:6,4,11&chs=250x100&chl=Hello|World The threshold appears to 'hit' when the total of the parameters in this example reaches 200. I haven't had time to experiment on larger numbers of datasets to find their threshold, but it appears to me so far that the threshold is at least partially a function of the number of datasets. I have a 6-slice pie that reaches it's threshold much later than 200, though I haven't had time to find out exactly what the number is. I thought I would write first and find out if this behavior is a design feature and there's some documentation I should read in order to program to the API correctly. If so, I'd appreciate being pointed. If not, let me know if I can assist in isolating the nature of the problem more exactly. Again, thanks very much to the Google team for this awsome library. I expect to make much use of it. Best regards, Bill -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
