My final requirement at this stage was to have something more graphical; a nice chart to show the trend of fans we have over time. The report designer allows the creation of charts using the KDChart library from KDAB and is used in the Calligra program KChart. It can be quite powerful, allowing the joining of chart data to the main report data (called master-child links), but for now, all I needed was a simple, single chart. The chart object expects data in a certain format. There must be 2 or more columns of data. The first column is used for the labels on the X axis, all other columns are used as series in the chart. I started by creating a query with 2 columns, date in ascending order and total fans, then created a new report. The report itself is not based on any data, so its Data Source was left empty. An empty data source will produce a report with 1 detail section, providing an area to add a minimal set of items to a report.
