* add reingold tillford tree layout algorithm * add first silly implementation of matplotlib based plotting for trees * object oriented design for export_graphviz so it can be extended * add class for mlp export * add colors * separately scale x and y, add arrowheads, fix strings * implement max_depth * don't use alpha for coloring because it makes boxes transparent * remove unused variables * vertical center of boxes * fix/simplify newline trimming * somewhere in the middle of stuff trying to get rid of scalex, scaley * remove "find_longest_child" for now, fix tests * make scalex and scaley internal, and ax local. render everything once to get the bbox sizes, then again to actually plot it with known extents. * add some margin to the max bbox width * add _BaseTreeExporter baseclass * add docstring to plot_tree * use data coordinates so we can put the plot in a subplot, remove some hacks. * remove scalex, scaley, add automatic font size * use rendered stuff for setting limits (well nearly there) * import plot_tree into tree module * set limits before font size adjustment? * add tree plotting via matplotlib to iris example and to docs * pep8 fix * skip doctest on plot_tree because matplotlib is not installed on all CI machines * redo everything in axis pixel coordinates re-introduce scalex, scaley add max_extents to tree to get tree size before plotting * fix max-depth parent node positioning and don't consider deep nodes in layouting * consider height in fontsize computation in case someone gave us a very flat figure * fix error when max_depth is None * add docstring for tree plotting fontsize * starting on jnothman's review * renaming fixes * whatsnew for tree plotting * clear axes prior to doing anything. * fix doctests * skip matplotlib doctest * trying to debug circle failure * trying to show full traceback * more print debugging * remove debugging crud * hack around matplotlib <1.5 issues * copy bbox args because old matplotlib is weird. * pep8 fixes * add explicit boxstyle * more pep8 * even more pep8 * add comment about matplotlib version requirement * remove redundant file * add whatsnew entry that the merge lost * fix merge issue * more merge issues * whitespace ... * remove doctest skip to see what's happening * added some simple invariance tests buchheim function * refactor ___init__ into superclass * added some tests of plot_tree * put skip back in, fix typo, fix versionadded number * remove unused parameters special_characters and parallel_leaves from mpl plotting * rename tests to test_reingold_tilford * added license header from pymag-trees repo * remove duplicate test file. |
