Hi there: The upcoming patch introduces functions as data providers for 3D plots, analogous to graph.data.function() and the like for 2D plots.
I also suggest enaming "functionxy", which does not correspond to graph.graphxy at all. In fact, current "functionxy" provides data for graph.graph only. It expects a function reference as parameter, which is why I suggest the name "functionlambda". (function parameters are most often specified as lambda expressions.) So, the implemented naming scheme for function type data providers is: functions specified as textual expressions: "function" 2D from expressions like "y(x)=..." "functionxy" 3d from expressions like "z(x,y)=..." functions specified as function references: "functionlambda" 2D from a function ref. with signature f(x) "functionxylambda" 3d from a function ref. with sign. f(x,y) parametric functions specified as textual expressions: "paramfunction" data depending on 1 parameter "paramtsfunction" data depending on 2 parameters parametric functions specified as function references: "paramfunctionlambda" data depending on 1 parameter "paramtsfunctionlambda" data depending on 2 parameters ["ts" for two parameters t, s] Cheers, Michael Notes: Parametric functions can provide 2D or 3D data (or anything else); PyX infers this from the textual expressions "x,y=..." or "x,y,z=..." resp. from the signature of the result of the function reference. Notably, the existing "paramfunction" can be used to draw 3D curves. Parametric 3D functions of 2 parameters, together with graph.style.surface() show some problems with the hidden surface logic, depending on the function. Maybe it assumes some ordering? The patch is against PyX 0.10 (r2907). If there's interest I'll rebase against trunk and provide docs/examples. Also, the patch is formatted by git-format-patch and friends off my git-svn clone of the sf repo, which prefers inline patches. I hope that's okay. The commit message would be subject + body of the upcoming mail, as for git-am. I know you guys prefer one-liners here, feel free to replace ;) Michael J Gruber (1): 3d function plots pyx/graph/data.py | 134 ++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 files changed, 132 insertions(+), 2 deletions(-) ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
