Express patterns that describe line dashes. ``DashPattern`` values can be specified in a variety of ways: * An enum: "solid", "dashed", "dotted", "dotdash", "dashdot" * a tuple or list of integers in the `HTML5 Canvas dash specification style`_. Note that if the list of integers has an odd number of elements, then it is duplicated, and that duplicated list becomes the new dash list. To indicate that dashing is turned off (solid lines), specify the empty list []. .. _HTML5 Canvas dash specification style: http://www.w3.org/html/wg/drafts/2dcontext/html5_canvas/#dash-list r)ZsolidZdashedZdottedZdotdashZdashdotNNonereturncs0ttjtdttf}tj|||ddS)Nz^(\d+(\s+\d+)*)?$defaulthelp)rr rrr rsuper__init__selfr$r%types __class__>/tmp/pip-unpacked-wheel-f5fndrjf/bokeh/core/property/visual.pyr'[szDashPattern.__init__strcCs|jjSNr,__name__r)r-r-r.__str___szDashPattern.__str__csTt|}t|trLz |j|WStk rHdd|DYSXn|SdS)NcSsg|] }t|qSr-)int).0xr-r-r. isz)DashPattern.transform..)r& transform isinstancer/_dash_patternsKeyErrorsplit)r)valuer+r-r.r9bs   zDashPattern.transform) r2 __module__ __qualname____doc__r;r'r4r9 __classcell__r-r-r+r.rAs  rcs,eZdZedejZdfdd ZZS)rzO^[0-9]+(.[0-9]+)?(%|em|ex|ch|ic|rem|vw|vh|vi|vb|vmin|vmax|cm|mm|q|in|pc|pt|px)$Tcsdt||t|tr`t|dkr:|s,dnd}t|n&|j|s`|sNdn|d}t|dS)Nrz+empty string is not a valid font size valuez is not a valid font size value)r&validater:r/len ValueError _font_size_rematchr)r>detailmsgr+r-r.rDqs     zFontSize.validate)T) r2r?r@recompileIrGrDrBr-r-r+r.rmsrcs:eZdZdZgdfddfdd Zdddd ZZS) rz Accept built-in fill hatching specifications.

Bounds are provided as a tuple of ``(min, max)`` so regardless of whether your range is increasing or decreasing, the first item should be the minimum value of the range and the second item should be the maximum. Setting min > max will result in a ``ValueError``. Setting bounds to None will allow your plot to pan/zoom as far as you want. If you only want to constrain one end of the plot, you can set min or max to ``None`` e.g. ``DataRange1d(bounds=(None, 12))`` FautoNr r!c stttttttttttttttttttttttf}|rr|tttttttttttf}tj|||ddSrO)r rrrrrr&r')r)Zaccept_datetimer$r%r*r+r-r.r's       zMinMaxBounds.__init__Tcst|||ddks&|ddkr*dSt|}t|dtjrRt|d|d<t|dtjrrt|d|d<|d|dkrdS|sdnd}t|dS)Nrr rCzNInvalid bounds: maximum smaller than minimum.
