# Diagrams

Diagrams are charts which are based on the data available in the report. Beware that even if a graph is placed in a band, the data used in that graph is taken from the whole report. Normally a diagram is positioned in bands that are only output once - otherwise diagrams are displayed multiple times.

To create a diagram, add a chart to your layout and click on 'Run Designer'.

Here, you can define via series, arguments and properties how the chart should look like.&#x20;

* The link between data and diagrams is made via series
* Every series contains a grouping argument (x-axis) and a value (y-axis) which is usually calculated using an aggregation function (sum, count, average, etc.)
* For the use of 2D diagrams, series can be added individually
