The mapping occurs in two stages. Firstly the RGB values are calculated using a weighted sum of the palette colors in the ``nstack`` direction. Then the alpha values are calculated using the ``alpha_mapper`` applied to the sum of the array in the ``nstack`` direction. The RGB values calculated by the ``alpha_mapper`` are ignored by the color mapping but are used in any ``ColorBar`` that is displayed. r*r+c:tj|i|dSr-r.r1s r6r0z!WeightedStackColorMapper.__init___r7r8zM Color mapper used to calculate the alpha values of the mapped data. rFa Baseline value used for the weights when calculating the weighted sum of palette colors. If ``None`` then the minimum of the supplied data is used meaning that values at this minimum have a weight of zero and do not contribute to the weighted sum. As a special case, if all data for a particular output pixel are at the color baseline then the color is an evenly weighted average of the colors corresponding to all such values, to avoid the color being undefined. aQ An optional sequence of strings to use as labels for the ``nstack`` stacks. If set, the number of labels should match the number of stacks and hence also the number of palette colors. The labels are used in hover tooltips for ``ImageStack`` glyphs that use a ``WeightedStackColorMapper`` as their color mapper. c|j{t|j}t|j}||kr|jd||_|d|dS||kr-t|jdg||z zz|_|d|dSdSdS)Nz != z , removing unwanted stack_labelsz, padding with empty strings) stack_labelsrErClist)r2nlabelnpalettes r6_check_label_lengthz,WeightedStackColorMapper._check_label_lengthys   (*++F4<((H  $($5ixi$@!
