X = [r.ITERATION_COUNT_MULTIPLIER for r in R]
Y = [r.AUTHORITATIVE_TIME for r in R]
Z = [r.time_overspent for r in R]

heatmap(X,Y,Z; size=(800,600))

results in:

and that can't be right, because for the bad column in the middle (at x=11),
it's y's are somehow offset by +0.05. As it can be seen from the repro, all y's are multiples of 0.1

Strangely, this does not work at all with GR/PythonPlot.

Hm, looking closer at the GR failure, this works:

heatmap(1:10, 1:10, rand(10,10))

but this fails:

julia> heatmap(1:10, 1:10, 1:10)
Error showing value of type Plots.Plot{Plots.GRBackend}:
ERROR: MethodError: no method matching heatmap_edges(::UnitRange{Int64}, ::Symbol, ::UnitRange{Int64}, ::Symbol, ::Tuple{Int64}, ::Bool)

Closest candidates are:
  heatmap_edges(::AbstractVector, ::Symbol, ::AbstractVector, ::Symbol, ::Tuple{Int64, Int64}, ::Bool)

but sometimes it fails with

julia> heatmap(1:10, 1:10, 1:10)
ERROR: expected 2-D array
Stacktrace:

So the issue is that plotly does not verify that Z is 2D.
