Make a bar chart

Briefly

Make a graph with one categorical attribute. By default you will get a bar chart.

Make an empty graph and drag the name of a categorical attribute to one of its axes.

By default, a bar chart shows the count of cases that belong to different groups. But you can change the meaning of the height of the bars by double-clicking on the "count" formula and editing it so that it computes whatever you want. For example, the bar chart shown here has bars whose height is the income of people over age 18.

You can also drag a categorical attribute into the middle of a bar chart and split the bars according to the categories shown in a legend. The graph below splits Year by Product and shows the sum of the Sales.

You can change a bar chart into a ribbon chart using the popup menu in the top-right corner of the graph.
