Ratios and Rates - Communicating Data with Tableau - page 71

Now the only task this chart doesn't facilitate is gleaning precise values. We could add the
labels to the right of the bars as we did in Figure 4-5 by simply dragging the Ratio field to
the Label shelf, but perhaps a better approach would be to add the labels to the left of the
bars so as not to interfere with the perception of the bars' lengths.
Because Recycle to Refuse Ratio is a continuous data field (the # symbol is green), if we
just drag it out onto the Rows shelf to the right of Borough & CommunityDistrict , Tableau
will create 59 y-axes for each of the bars. Try it and see what I mean.
We just want the ratio value itself to appear, so we'll first convert Recycle to Refuse Ra-
tio to a discrete field the same way we converted Rank , and then we'll drag the ratio onto
the Rows shelf to the far right, leaving a blue pill and creating the updated view shown in
Figure 4-12 .
