The Spider Web Chart can be used for presenting data with one dimension and one or more aggregations. The data will be displayed in the form of a spider web with the radial connections from the middle to the edges defining the axis of the chart. In theory it allows adding an infinite number of aggregations. However, as there is just one axis, only aggregations within a similar value range will deliver a reasonable result. An example for a Spider Web Chart can be seen in Figure 2.26.

Interaction with the Spider Web Chart
The Spider Web Chart is the only chart that does not allow for any filtering or zooming.
As can be seen in Figure 2.26, a legend at the bottom of the chart shows the dimensions of the Scatter Plot. By clicking on one of the legend entries, it is possible to hide single correlations from the chart. However, this only makes sense if there there is more than one aggregation involved, otherwise the one data series displayed will simply disappear. If a correlation is in hidden mode, its respective legend entry will be greyed out and the correlation will not be shown in the Spider Web Chart. Clicking its legend entry again will make the data series reappear.
If export was allowed during the configuration of the Spider Web Chart, the data providing the basis for the chart can be exported in View-Mode. In that case, a small disk icon (
) will appear on top of the chart. Clicking on it will lead to a download of the chart’s content as an xlsx file.
