Line charts
Line charts connect specific data values with lines, either horizontally or vertically. Line
charts are useful if you want to show trends or changes in data over time. There are five
types of line charts: mixed, stacked, percent, 3D, and 3D surface.
Area charts
Area charts are line charts in which the area between the lines and axis are filled in. Area
charts are useful if you want to emphasize the size of the total data in a report, as opposed
to the changes in the data. You may not want to use an area chart if you have a sharp
contrast between specific data points. Use a line chart instead.
You can use more than one measure object on the Y-axis as long as the measures are of
the same type and scale; for example, Number of Guests, and Future Guests. There are
five types of area charts: absolute, stacked, percent, 3D area, and 3D surface.
Pie charts
Pie charts display data as segments of a whole. Pie charts are useful if you want to show
how each part of your report data contributes to the total.
You can only include one measure object in a pie chart. If you have several measures in
your report, you should choose another chart type. There are four types of pie charts: pie,
3D pie, ring, 3D ring.
Radar, Polar, and scatter charts
In radar charts, the X- and Y-axis connect at the chart’s center. Radar charts are useful if
you want to look at several different factors related to one item. For example, you could
use a radar chart to display revenue data for different services within a hotel. On one axis,
you could display revenue for the rooms. On another you could display revenue for the
restaurant, and so on.
Scatter charts are similar to line graphs, except that the data points are plotted without a
line connecting them. Scatter charts are useful if you want to make a comparison between
specific data points.
There are four types of radar, polar, and scatter charts: radar line, stacked radar, polar,
and scatter.
Creating charts
You can include one or multiple charts on the reports in a Web Intelligence document. You
can create a chart when you build or new document or insert charts into an existing
document.
If you are building a new document, you need to define the data definition of the
document by building a query before you select a chart template. For full information on
building data providers see ”Building basic data providers” on page 33.
