Module: plotwrap

*** For now, plotwrap is hardwired for TkAgg this is not great, but also not a high priority to fix for now; PlotWinP might be the start of a decent fix

but plotwrap was built with the idea that you could have a plot without a window, and pyplot relies on the new_figure_manager functions in the backends, which always make a window; what we need is something to make the figure and the canvas without the figure manager ... but FigureCanvasMac

... how does one get a drawable figure that is not necessarily drawn?!

4 Classes

class hexrd.plotwrap.PlotWin(numRows=1, numCols=-1, title='PlotWin window', figure=None, relfigsize=(3, 3), axesList=None, noAutoAxesList=False, dpi=100)

__init__(numRows=1, numCols=-1, title='PlotWin window', figure=None, relfigsize=(3, 3), axesList=None, noAutoAxesList=False, dpi=100)

If pass negative numCols, then numRows is the number of plots and the layout is done automatically

getAxes(plotNum, rect=None, withPW=False, **axprops)

careful: plotNum is from 0, not 1 as is the case for subplot axprops is useful for this like setting sharex and sharey

class hexrd.plotwrap.PlotWinLite(canvas, figure, axes)

Lightweight PlotWin substitute for when windows are being controlled by code outside of plotwrap

__init__(canvas, figure, axes)

haveXLabels()

may want to turn off any functionality in this method

haveYLabels()

may want to turn off any functionality in this method

class hexrd.plotwrap.PlotWinP(axes=None, as3D=False, title=None, **kwargs)

Just wrap pyplot

__init__(axes=None, as3D=False, title=None, **kwargs)

haveXLabels()

may want to turn off any functionality in this method

haveYLabels()

may want to turn off any functionality in this method

pwList = None

for now, punt on setting a title

class hexrd.plotwrap.PlotWrap(**keyArgs)

Bases: object

__init__(**keyArgs)

colorbar(rect=(0.8, 0.1, 0.05, 0.8), adjustPos=True, thing=None, **kwargs)

if set rect to None, then colorbar steals self.a

destroy()

does not clean up self.a, just kills the window if this plot owns the window

ownCanvas = None

checking self.showByDefault here causes trouble because it is hard to attach a figure to a window later for a general backend ***

save(**keyArgs)

make hardcopy of the current figure; specify filename or prefix keyword argument

6 Functions

hexrd.plotwrap.autoTicks(x, n, format='%0.2e')

hexrd.plotwrap.argToPW(arg)

hexrd.plotwrap.hist2D(xVals, yVals, bins, hRange=None, weights=None, **kwArgs)

Plot 2D histogram of data yVals versus xVals, with number of bins given by bins (int or 2-tuple)

hexrd.plotwrap.plotHist2D(xedges, yedges, H, hRange=None, logScale=False, minCount=1, win=None, xlabel=None, ylabel=None, xformat=None, yformat=None, nXTics=0, nYTics=0, winArgs={})

winArgs can include things like title, relfigsize, dpi

hexrd.plotwrap.makeHist2D(xVals, yVals, bins, hRange=None, weights=None)

hexrd.plotwrap.main()
