    <p>So I am trying to make a stacked bar graph with bar width mapped to a variable; but I want the spacing between my bars to be constant.</p> <p>Does anyone know how to make the spacing constant between the bars?</p> <p>Right now I've got this:</p> <pre><code>p&lt;-ggplot(dd, aes(variable, value.y, fill=Date, width=value.x / 15))+ coord_flip() + opts(ylab="") p1&lt;-p+ geom_bar(stat="identity") + scale_fill_brewer(palette="Dark2") + scale_fill_hue(l=55,c=55) p2&lt;-p1 + opts(axis.title.x = theme_blank(), axis.title.y = theme_blank()) p2 </code></pre> <p><img src="https://i.stack.imgur.com/62k6s.jpg" alt="enter image description here"></p> <p>Thanks in advance.</p> <p>Here's my data by the way (sorry for the long, bulky dput):</p> <pre><code>&gt; dput(dd) structure(list(variable = structure(c(1L, 1L, 1L, 1L, 1L, 3L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L, 4L, 7L, 7L, 7L, 7L, 7L, 2L, 2L, 2L, 2L, 2L, 6L, 6L, 6L, 6L, 6L, 5L, 5L, 5L, 5L, 5L, 9L, 9L, 9L, 9L, 9L, 8L, 8L, 8L, 8L, 8L), .Label = c("Alcohol and Tobacco", "Health and Personal Care", "Clothing", "Energy", "Recreation and Education", "Household", "Food", "Transportation", "Shelter"), class = "factor", scores = structure(c(2.91, 5.31, 10.08, 15.99, 4.95, 11.55, 11.2, 27.49, 20.6), .Dim = 9L, .Dimnames = list( c("Alcohol and Tobacco", "Clothing", "Energy", "Food", "Health and Personal Care", "Household", "Recreation and Education", "Shelter", "Transportation" )))), value.x = c(2.91, 2.91, 2.91, 2.91, 2.91, 5.31, 5.31, 5.31, 5.31, 5.31, 10.08, 10.08, 10.08, 10.08, 10.08, 15.99, 15.99, 15.99, 15.99, 15.99, 4.95, 4.95, 4.95, 4.95, 4.95, 11.55, 11.55, 11.55, 11.55, 11.55, 11.2, 11.2, 11.2, 11.2, 11.2, 27.49, 27.49, 27.49, 27.49, 27.49, 20.6, 20.6, 20.6, 20.6, 20.6), Date = structure(c(5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L, 5L, 4L, 3L, 2L, 1L), .Label = c("1993-2001", "2001-2006", "2007-2010", "2010-2011", "2012 Jan - May"), class = "factor"), value.y = c(2.1, 2.5, 7.6, 21.7, 2.8, 1.5, 0.3, -4.1, -4.2, 4.7, 3, 16.9, 1.9, 32.8, 23.9, 3.2, 4.6, 11.3, 8.9, 12.9, 1.7, 2, 7.8, 5.9, 10, 1.9, 2.1, 5.6, 2.2, 9.9, 1.4, 1.3, 2.2, 0.6, 17.3, 1.1, 2.3, 6.4, 13.1, 10, 4.3, 7.6, 0.9, 15.2, 20.5)), .Names = c("variable", "value.x", "Date", "value.y" ), row.names = c(NA, -45L), class = "data.frame") </code></pre>

    1. COYou may want to consider using + facet_grid(~Date). It makes for a much more readable graph.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
