layout bug (?) when plotting histogram with logarithmic y axis

Those lines going up there are the vertical drop line (I supposed) that all go somewhere top left. This is my code:
plotFrequencies
:: IO ()
plotFrequencies = do
ls <- lines <$> readFile "deu_news_2020_freq.txt"
let ns = tail ls <&> \l -> case splitOn "\t" l of
[_, n'] -> read $ Text.unpack n'
_ -> error "missing tab character?"
renderableToWindow (chart $ dropWhile (> 200) ns) 800 600
where
chart
:: [Double]
-> Renderable ()
chart ns =
toRenderable $ def
& layout_plots .~ [histogram ns]
& layout_title .~ "Frequency"
& layout_x_axis . laxis_generate .~ scaledAxis
( def & la_nLabels .~ 200
& la_nTicks .~ 200
) (1, 200)
& layout_y_axis . laxis_generate .~ autoScaledLogAxis def
histogram
:: [Double]
-> Plot Double Double
histogram ns =
histToPlot $ defaultFloatPlotHist
& plot_hist_values .~ ns
& plot_hist_bins .~ 200
& plot_hist_title .~ "#Total shown: " <> show (length ns)
& plot_hist_range ?~ (0, 200)
