Description

bar3h draws three-dimensional horizontal bar charts.

bar3h(Y) draws a three-dimensional bar chart, where each element in Y corresponds to one bar. When Y is a vector, the z-axis scale ranges from 1 to length(Y). When Y is a matrix, the z-axis scale ranges from 1 to the number of rows in Y.

bar3h(Z,Y) draws a bar chart of the elements in Y at the locations specified in Z, where Z is a vector defining the z values for the horizontal bars. The z values can be nonmonotonic, but cannot contain duplicate values. If Y is a matrix, elements from the same row in Y appear at the same location along the z-axis.

bar3h(...,width) sets the width of the bars and controls the separation of bars within a group. The default width is 0.8 and the bars have a slight separation. If width is 1, then the bars within a group touch one another.

bar3h(...,style) specifies the style of the bars. style is 'detached', 'grouped', or 'stacked'. Default mode of display is 'detached'.

• 'detached' displays the elements of each row in Y as separate blocks behind one another in the x direction.

• 'grouped' displays n groups of m horizontal bars, where n is the number of rows and m is the number of columns in Y. Each group contains one bar per column in Y.

• 'stacked' displays one bar for each row in Y. The bar length is the sum of the elements in the row. Each bar is multicolored, with colors corresponding to distinct elements and showing the relative contribution each row element makes to the total sum.

bar3h(...,color) displays all bars using the color specified by color. For example, use 'r' for red bars. Specify color as one of these values: 'r', 'g', 'b', 'c', 'm', 'y', 'k', or 'w'.

bar3h(ax,...) plots into the axes ax instead of into the current axes (gca).

h = bar3h(...) returns a vector Surface objects. When Y is a matrix, bar3h creates one Surface object per column in Y.

Examples

Load the data set count.dat, which returns a three-column matrix, count. Store Y as the first ten rows of count.

Y = count(1:10,:);

Create a 3-D horizontal bar graph of Y. By default, the style is detached.

Create a 3-D horizontal bar graph of Y and set the bar width to 0.5.

width = 0.5;
