请问下，有什么包绘制直方图可以指定纵轴为密度吗
直接用 Plots
help?> histogram
search: histogram histogram! histogram2d histogram2d!
histogram(x)
histogram!(x)
Plot a histogram.
Arguments
≡≡≡≡≡≡≡≡≡≡≡
• x: AbstractVector of values to be binned
• bins: Integer, NTuple{2,Integer}, AbstractVector or Symbol. Default is :auto (the Freedman-Diaconis rule). For histogram-types, defines the
approximate number of bins to aim for, or the auto-binning algorithm to use (:sturges, :sqrt, :rice, :scott or :fd). For fine-grained control
pass a Vector of break values, e.g. range(minimum(x), stop = maximum(x), length = 25)
• weights: Vector of weights for the values in x, for weighted bin counts
• normalize: Bool or Symbol. Histogram normalization mode. Possible values are: false/:none (no normalization, default), true/:pdf (normalize
to a discrete Probability Density Function, where the total area of the bins is 1), :probability (bin heights sum to 1) and :density (the
area of each bin, rather than the height, is equal to the counts - useful for uneven bin sizes).
• bar_position: Symbol. Choose from :overlay (default), :stack. (warning: May not be implemented fully)
• bar_width: nothing or Number. Width of bars in data coordinates. When nothing, chooses based on x (or y when orientation = :h).
• bar_edges: Bool. Align bars to edges (true), or centers (the default)?
• orientation: Symbol. Horizontal or vertical orientation for bar types. Values :h, :hor, :horizontal correspond to horizontal (sideways,
anchored to y-axis), and :v, :vert, and :vertical correspond to vertical (the default).
Example
≡≡≡≡≡≡≡≡≡
julia> histogram([1,2,1,1,4,3,8],bins=0:8)
julia> histogram([1,2,1,1,4,3,8],bins=0:8,weights=weights([4,7,3,9,12,2,6]))
对于你的需求
histogram(A,normalize=:probability)
你好，我想在这个图的里面加条拟合曲线要怎么加？
你好，请问下，直方图可以转成散点图的形式吗？（纵轴还是表示密度）
