    <p>does anyone know if it is possible to exclude zero values from a barplot in ggplot?</p> <p>I have a dataset that contains proportions as follows:</p> <pre><code> X5employf prop X5employff 1 increase 0.02272727 2 increase 0.59090909 1 3 increase 0.02272727 1 and 8 4 increase 0.02272727 2 5 increase 0.34090909 3 6 increase 0.00000000 4 7 increase 0.00000000 5 8 increase 0.00000000 6 9 increase 0.00000000 6 and 7 10 increase 0.00000000 6 and 7 11 increase 0.00000000 7 12 increase 0.00000000 8 13 decrease 0.00000000 14 decrease 0.00000000 1 15 decrease 0.00000000 1 and 8 16 decrease 0.00000000 2 17 decrease 0.00000000 3 18 decrease 0.10000000 4 19 decrease 0.50000000 5 20 decrease 0.20000000 6 21 decrease 0.00000000 6 and 7 22 decrease 0.00000000 6 and 7 23 decrease 0.10000000 7 24 decrease 0.10000000 8 25 same 0.00000000 26 same 0.00000000 1 27 same 0.00000000 1 and 8 28 same 0.00000000 2 29 same 0.00000000 3 30 same 0.21052632 4 31 same 0.31578947 5 32 same 0.26315789 6 33 same 0.15789474 6 and 7 34 same 0.00000000 6 and 7 35 same 0.05263158 7 36 same 0.00000000 8 </code></pre> <p>as you can see in the 'prop' column there are a lot of zero values. I am producing a facetted bar plot with 'X5employf' column as the facet. But because of the zero values I end up with a lot of empty space on my plot(see below). Is there a way of forcing ggplot to not plot the zero values? Its not the case of dropping unused factors as these are not NA values but 0s. Any ideas??!</p> <p><img src="https://i.stack.imgur.com/PlreC.png" alt="example plot"></p>

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.
