 ## master
-- Allow arbitrary reversible scale functions through `ReversibleScale`.
+- Fix grouping of a zero-height bar in `barplot`. Now a zero-height bar shares the same properties of the previous bar, and if the bar is the first one, its height is treated as positive if and only if there exists a bar of positive height or all bars are zero-height. [#3058](https://github.com/MakieOrg/Makie.jl/pull/3058)
+- Fixed a bug where Axis still consumes scroll events when interactions are disabled [#3272](https://github.com/MakieOrg/Makie.jl/pull/3272)
+- Added `cornerradius` attribute to `Box` for rounded corners [#3308](https://github.com/MakieOrg/Makie.jl/pull/3308).
+- Upgraded `StableHashTraits` from 1.0 to 1.1 [#3309](https://github.com/MakieOrg/Makie.jl/pull/3309).
+
+## v0.19.11
+
+- Setup automatic colorbars for volumeslices [#3253](https://github.com/MakieOrg/Makie.jl/pull/3253).
+- Colorbar for arrows [#3275](https://github.com/MakieOrg/Makie.jl/pull/3275).
+- Small bugfixes [#3275](https://github.com/MakieOrg/Makie.jl/pull/3275).
+
+## v0.19.10
 
+- Fix bugs with Colorbar in recipes, add new API for creating a recipe colorbar and introduce experimental support for Categorical colormaps [#3090](https://github.com/MakieOrg/Makie.jl/pull/3090).
+- Add experimental Datashader implementation [#2883](https://github.com/MakieOrg/Makie.jl/pull/2883).
+- [Breaking] Changed the default order Polar arguments to (theta, r). [#3154](https://github.com/MakieOrg/Makie.jl/pull/3154)
+- General improvements to `PolarAxis`: full rlimtis & thetalimits, more controls and visual tweaks. See pr for more details.[#3154](https://github.com/MakieOrg/Makie.jl/pull/3154)
+
+## v0.19.9
+
+- Allow arbitrary reversible scale functions through `ReversibleScale`.
 - Deprecated `linestyle=vector_of_gaps` in favor of `linestyle=Linestyle(vector_of_gaps)` [3135](https://github.com/MakieOrg/Makie.jl/pull/3135), [3193](https://github.com/MakieOrg/Makie.jl/pull/3193).
 - Fixed some errors around dynamic changes of `ax.xscale` or `ax.yscale` [#3084](https://github.com/MakieOrg/Makie.jl/pull/3084)
 - Improved Barplot Label Alignment [#3160](https://github.com/MakieOrg/Makie.jl/issues/3160).

+# How to save a `Figure` with transparency
+
+## CairoMakie
+
+In CairoMakie, set the background color to `:transparent` (converts to `RGBAf(0, 0, 0, 0)`) to get a fully transparent background.
+In the following examples, I use a partially transparent blue because a transparent background is indistinguishable from the usual white on a white page.
+
+\begin{examplefigure}{svg = true}
+```julia
+using CairoMakie
+CairoMakie.activate!() # hide
+
+f = Figure(backgroundcolor = (:blue, 0.4))
+Axis(f[1, 1], backgroundcolor = (:tomato, 0.5))
+f
+```
+\end{examplefigure}
+
+## GLMakie
+
+For technical reasons, GLMakie's color buffer does not have an alpha component:
+
+\begin{examplefigure}{}
+```julia
+using GLMakie
+GLMakie.activate!() # hide
+Makie.inline!(true) # hide
+
+f = Figure(backgroundcolor = (:blue, 0.4))
+Axis(f[1, 1], backgroundcolor = (:tomato, 0.5))
+f
+```
+\end{examplefigure}
+
+
+With the following trick you can still save an image with transparent background.
+It works by setting two different background colors and calculating the foreground color with alpha from the difference.
+
+```julia:transparent-glmakie
+using GLMakie
+GLMakie.activate!() # hide
+Makie.inline!(true) # hide
+
+function calculate_rgba(rgb1, rgb2, rgba_bg)::RGBAf
+    rgb1 == rgb2 && return RGBAf(rgb1.r, rgb1.g, rgb1.b, 1)
+    c1 = Float64.((rgb1.r, rgb1.g, rgb1.b))
+    c2 = Float64.((rgb2.r, rgb2.g, rgb2.b))
+    alphas_fg = 1 .+ c1 .- c2
+    alpha_fg = clamp(sum(alphas_fg) / 3, 0, 1)
+    alpha_fg == 0 && return rgba_bg
+    rgb_fg = clamp.((c1 ./ alpha_fg), 0, 1)
+    rgb_bg = Float64.((rgba_bg.r, rgba_bg.g, rgba_bg.b))
+    alpha_final = alpha_fg + (1 - alpha_fg) * rgba_bg.alpha
+    rgb_final = @. 1 / alpha_final * (alpha_fg * rgb_fg + (1 - alpha_fg) * rgba_bg.alpha * rgb_bg)
+    return RGBAf(rgb_final..., alpha_final)
+end
+
+function alpha_colorbuffer(figure)
+    scene = figure.scene
+    bg = scene.backgroundcolor[]
+    scene.backgroundcolor[] = RGBAf(0, 0, 0, 1)
+    b1 = copy(colorbuffer(scene))
+    scene.backgroundcolor[] = RGBAf(1, 1, 1, 1)
+    b2 = colorbuffer(scene)
+    scene.backgroundcolor[] = bg
+    return map(b1, b2) do b1, b2
+        calculate_rgba(b1, b2, bg)
+    end
+end
+
+f = Figure(backgroundcolor = (:blue, 0.4))
+Axis(f[1, 1], backgroundcolor = (:tomato, 0.5))
+f
+

+The order of a arguments can be changed with `ax.theta_as_x`.

+## PolarAxis Limits
+
+By default the PolarAxis will assume `po.rlimits[] = (0.0, nothing)` and `po.thetalimits[] = (0.0, 2pi)`, showing a full circle.
+You can adjust these limits to show different cut-outs of the PolarAxis.
+For example, we can limit `thetalimits` to a smaller range to generate a circle sector and further limit rmin through `rlimits` to cut out the center to an arc.
+

+f = Figure(resolution = (600, 600))
+
+ax = PolarAxis(f[1, 1], title = "Default")

+ax = PolarAxis(f[1, 2], title = "thetalimits", thetalimits = (-pi/6, pi/6))
+lines!(ax, range(0, 8pi, length=300), range(0, 10, length=300))
+

+thetalims!(ax, -pi/6, pi/6)
+rlims!(ax, 5, 10)
+
+f
+```
+\end{examplefigure}
+
+You can make further adjustments to the orientation of the PolarAxis by adjusting `ax.theta_0` and `ax.direction`.
+These adjust how angles are interpreted by the polar transform following the formula `output_angle = direction * (input_angle + theta_0)`.
+
+\begin{examplefigure}{svg = true}
+```julia
+f = Figure()
+
+ax = PolarAxis(f[1, 1], title = "Reoriented Axis", theta_0 = -pi/2, direction = -1)
+lines!(ax, range(0, 8pi, length=300), range(0, 10, length=300))
+thetalims!(ax, -pi/6, pi/6)
+rlims!(ax, 5, 10)
+
+f
+```
+\end{examplefigure}
+
+Note that by default translations in adjustments of rmin and thetalimits are blocked.
+These can be unblocked by calling `autolimits!(ax[, true])` which also tells the PolarAxis to derive r- and thetalimits freely from data, or by setting `ax.fixrmin[] = false` and `ax.thetazoomlock[] = false`.
+
+
+## Plot type compatability

+For example `image` is not as it expects to be drawn on a rectangle.

 ## Interactivity

-combination for resetting the view with the `reset_button` attribute, which
-accepts anything `ispressed` accepts.
+The `PolarAxis` currently implements zooming, translation and resetting.
+Zooming is implemented via scrolling, with `ax.rzoomkey = Keyboard.r` restricting zooming to the radial direction and `ax.thetazoomkey = Keyboard.t` restring to angular zooming.
+You can block zooming in the r-direction by setting `ax.rzoomlock = true` and `ax.thetazoomlock = true` for theta direction.
+Furthermore you can disable zooming from changing just rmin with `ax.fixrmin = true` and adjust its speed with `ax.zoomspeed = 0.1`.
+
+Translations are implemented with mouse drag.
+By default radial translations use `ax.r_translation_button = Mouse.right` and angular translations also use `ax.theta_translation_button = Mouse.right`.
+If `ax.fixrmin = true` translation in the r direction are not allowed.
+If you want to disable one of these interaction you can set corresponding button to `false`.
 
-Note that `PolarAxis` currently does not implement the interaction itnerface
+There is also an interaction for rotating the whole axis using `ax.axis_rotation_button = Keyboard.left_control & Mouse.right` and resetting the axis view uses `ax.reset_button = Keyboard.left_control & Mouse.left`, matching `Axis`.

 ## Other Notes
 
 ### Plotting outside a PolarAxis

-which clips the content to the relevant area. If you want to draw outside the
-circle limiting the polar axis but still within it's scene area, you will need
+Currently there are two poly plots outside the area of the `PolarAxis`
+which clip the content to the relevant area. If you want to draw outside the
+clip limiting the polar axis but still within it's scene area, you need
 to translate those plots to a z range between `9000` and `10_000` or disable
 clipping via the `clip` attribute.
 
+For reference, the z values used by `PolarAxis` are `po.griddepth[] = 8999` for grid lines, 9000 for the clip polygons, 9001 for spines and 9002 for tick labels.
+
+### Radial Distortion
+
+If you have a plot with a large rmin and rmax over a wide range of angles you will end up with a narrow PolarAxis.
+Consider for example:
+
+\begin{examplefigure}{svg = true}
+```julia
+fig = Figure()
+ax = PolarAxis(fig[1, 1], thetalimits = (0, pi))
+lines!(ax, range(0, pi, length=100), 10 .+ sin.(0.3 .* (1:100)))
+fig
+```
+\end{examplefigure}
+
+In this case you may want to distort the r-direction to make more of your data visible.
+This can be done by setting `ax.radial_distortion_threshold` to a value between 0 and 1.
+
+\begin{examplefigure}{svg = true}
+```julia
+fig = Figure()
+ax = PolarAxis(fig[1, 1], thetalimits = (0, pi), radial_distortion_threshold = 0.2, rlimits = (nothing, nothing))
+lines!(ax, range(0, pi, length=100), 10 .+ sin.(0.3 .* (1:100)))
+fig
+```
+\end{examplefigure}
+
+Internally PolarAxis will check `rmin/rmax` against the set threshold.
+If that ratio exceed the threshold, the polar transform is adjusted to shift all radii by some `r0` such that `(rmin - r0) / rmax - r0) == ax.radial_distortion_threshold`.
+In effect this will hold the inner cutout/clip radius at a fraction of the outer radius.
+Note that at `ax.radial_distortion_threshold >= 1.0` (default) this will never distort your data.

+

+```julia
+datashader(one_category_per_point, points)
+datashader(Dict(:category_a => all_points_a, :category_b => all_points_b))
+```
+
+The type of the category doesn't matter, but will get converted to strings internally, to be displayed nicely in the legend.
+Categories are currently aggregated in one Canvas per category, and then overlayed with alpha blending.
+
+\begin{examplefigure}{}
+```julia
+normaldist = randn(Point2f, 1_000_000)
+ds1 = normaldist .+ (Point2f(-1, 0),)
+ds2 = normaldist .+ (Point2f(1, 0),)
+fig, ax, pl = datashader(Dict("a" => ds1, "b" => ds2))
+hidedecorations!(ax)
+fig
+```
+\end{examplefigure}
+
+We can also re-use the previous NYC example for a categorical plot:
+```julia
+@time begin
+    f = Figure(figure_padding=0, resolution=(1200, 600))
+    ax = Axis(
+        f[1, 1],
+        autolimitaspect=1,

+### Advanced API
+
+The `datashader` recipe makes it very simple to get started, and is also efficiently implemented so that most changes like `f, ax, pl = datashader(...); pl.colorrange=new_range; pl.operation=log10` won't redo the aggregation.
+But if you still need more manual control, one can also use the underlying `Canvas` API directly for more manual control:

+    datashader(points::AbstractVector{<: Point})
+
+!!! warning
+    This feature might change outside breaking releases, since the API is not yet finalized.
+    Please be vary of bugs in the implementation and open issues if you encounter odd behaviour.
+
+Points can be any array type supporting iteration & getindex, including memory mapped arrays.
+If you have separate arrays for x and y coordinates and want to avoid conversion and copy, consider using:
+```Julia
+using Makie.StructArrays
+points = StructArray{Point2f}((x, y))
+datashader(points)
+```
+Do pay attention though, that if x and y don't have a fast iteration/getindex implemented, this might be slower then just copying it into a new array.
+
+For best performance, use `method=Makie.AggThreads()` and make sure to start julia with `julia -tauto` or have the environment variable `JULIA_NUM_THREADS` set to the number of cores you have.
+
+## Attributes
+
+### Specific to `DataShader`
+
+- `agg = AggCount()` can be `AggCount()`, `AggAny()` or `AggMean()`. User extendable by overloading:
+
+
+    ```Julia
+        struct MyAgg{T} <: Makie.AggOp end
+        MyAgg() = MyAgg{Float64}()
+        Makie.Aggregation.null(::MyAgg{T}) where {T} = zero(T)
+        Makie.Aggregation.embed(::MyAgg{T}, x) where {T} = convert(T, x)
+        Makie.Aggregation.merge(::MyAgg{T}, x::T, y::T) where {T} = x + y
+        Makie.Aggregation.value(::MyAgg{T}, x::T) where {T} = x
+    ```
+
+- `method = AggThreads()` can be `AggThreads()` or `AggSerial()`.
+- `async::Bool = true` will calculate get_aggregation in a task, and skip any zoom/pan updates while busy. Great for interaction, but must be disabled for saving to e.g. png or when inlining in documenter.
+
+- `operation::Function = automatic` Defaults to `Makie.equalize_histogram` function which gets called on the whole get_aggregation array before display (`operation(final_aggregation_result)`).
+- `local_operation::Function = identity` function which gets call on each element after the aggregation (`map!(x-> local_operation(x), final_aggregation_result)`).
+
+- `point_transform::Function = identity` function which gets applied to every point before aggregating it.
+- `binsize::Number = 1` factor defining how many bins one wants per screen pixel. Set to n > 1 if you want a corser image.
+- `show_timings::Bool = false` show how long it takes to aggregate each frame.
+- `interpolate::Bool = true` If the resulting image should be displayed interpolated.
