Curious what y'all think about this approaching of highlighting the incremental change in each step of a stacked area by using a different shade. I think it's valuable to highlight in this case, but I'm concerned that people will interpret the darker shades as separate data series instead. Any suggestions for alternatives?https://vis.social/media/IVy964ktBs0PFow48SI
Issue 1: yes, that's tricky. Strong labeling will help. How dedicated is your audience?
Issue 2: stacked bars are a better representation of proportion per group, but not easy to compare incremental group changes.
Issue 3: This emphasizes the size of the pending group, but makes all others more challenging.
Issue 4: what if a group shrinks?
Bottom line: what's the most important take-away message / data points?
@veltman Interesting, never seen something like this before. How about using a gradient (from lighter to full shade) to show the "extension" of the bar in the new period? It's not stacked bars, but here's something similar I did recently, to give you a visual of my description (forget the arrows). https://vis.social/media/1hnYQhqbM1MJl1v-8KI
@veltman maybe flip it vertically? the coloured bars growing up would be more "natural" to me. if the part-to-whole relationship is not that central, i might think about three "small multiples" of bars starting each from a zero baseline, then the growth is even more obvious.
@1wheel I've tried a few different pattern fills, e.g. https://vis.social/media/qOD7HboLmIs8iFrBY0E, but been struggling to find a pairing that feels like it puts the focus on the incremental and also makes the larger group clear... another kooky idea I had was to put little bars or arrows in the corner instead, but that just wound up looking like cuisenaire rods https://vis.social/media/mLARlfFvMSlhUyseYhc
@veltman for fun a few months ago, I snuck in a weird way to add context to a stacked area chart here (click on a segment to see) http://www.latimes.com/projects/la-pol-sac-california-climate-change/
