    Input Arguments

    expand all

    heights — y-coordinates. Vector.

    Vector Vector of length k containing numeric values describing the bars which make up the plot.

    Data Types: single| double

    classes — classes of the frequency distribution. Vector.

    Vector of length k+1 containing numeric values describing the widths of the bars which make up the plot. classes(1) contains the starting point of the first bar on the x axis, and classes(end) contains the end point of the last bar on the x axis.

    For example if classes=[0.5 0.6 0.9 1 1.2]; the first baar has x coordinates [0.5 0.6], the second bar has x coordinates [0.6 0.9], the third has x coordinates [0.9 1] and the fourth has x coordinates [1 1.2]

    Data Types: single| double

    Name-Value Pair Arguments

    Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes (' '). You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

    Example: 'color',1:5 , 'LineWidth',2 , 'FaceAlpha',0.8 , 'EdgeColor',[0 0.5 1] , 'LineStyle','--']

    Color —Rectangle colors.scalar | vector | matrix | RGB triplet | 'r' | 'g' | 'b' | .

    Rectangle colors, specified as a scalar, vector, matrix, or a color name.

    Example: 'color',1:5

    Data Types: scalar | vector | matrix | RGB triplet | 'r' | 'g' | 'b' | .

    LineWidth —Line Width of the vertices.scalar.

    Scalar containing the width of the lines of the rectangles.

    Example: 'LineWidth',2

    Data Types: double

    FaceAlpha —Face transparency.1 (default) | scalar in range [0,1] | 'flat' | 'interp'.

    A value of 1 is fully opaque and 0 is completely transparent.

    For additional details about this option see option FaceAlpha inside patch.

    Example: 'FaceAlpha',0.8

    Data Types: double

    EdgeColor —Edge colors.[0 0 0] (default) | 'none' | 'flat' | 'interp' | RGB triplet | hexadecimal color code | 'r' | 'g' | 'b' | .

    Colors of the edges of the rectangles.

    For additional details about this option see option FaceAlpha inside patch.

    Example: 'EdgeColor',[0 0.5 1]

    Data Types: | 'none' | 'flat' | 'interp' | RGB triplet | hexadecimal color code | 'r' | 'g' | 'b' |

    LineStyle —Line style.'-' (default) | '--' | ':' | '-.

    ' | 'none'' Line Style of the edges of the rectangles.

    Example: 'LineStyle','--']

    Data Types: '-' (default) | '--' | ':' | '-.' | 'none''
