Selections in charts
Besides selections in list-boxes, we can also directly select data in charts. Let's jump
to the
Dashboard
tab and see how this is done. The
Dashboard
tab contains a chart
labeled
Number of Movies
, which lists the number of movies by a particular actor.
If we wish to select only the top three actors, we can simply drag the pointer to select
them in the chart, instead of selecting them from a list-box:
Because the selection automatically cascades to the rest of the model, this also results
in the
Actor
list-box being updated to reflect the new selection:
Of course, if we want to select only a single value in a chart, we don't necessarily
need to lasso it. Instead, we can just click on the data point to select it. For example,
clicking on
James Stewart
leads to only that actor being selected.
Search
While list-boxes and lassoing are both very convenient ways of selecting data,
sometimes we may not want to scroll down a big list looking for a value that may
or may not be there. This is where the search option comes in handy.
