Mini Chart in crosstab row

Case:

You want to display a mini chart in the row of a crosstab.

Solution:

Create a crosstab report with for example: Product-line, year and sales.

Go to the Query Explorer and rename Query1 to Crosstab.

Go to the Query Explorer and copy the Crosstab query. Then click paste and rename the query to Chart.

Create a line chart with the query Chart as source. Add year-month from the date dimension into the query.

From the query drag year-month into the X-axis Catagory. Then drag Sales into Y-axis Default measure.

Define a sort on the X-axis. Select the abc on the X-axis, go to the properties and choose NO for Visible. Select the Y-axis and go to the properties and choose NO for Visible. In the properties of the Chart set Hide for Legend.

Set the size of the graph to 70px (height) and 140px (width) in the Size&Overflow properties of the Chart.

Unlock all objects in the report.

Drag a table into the row with the productlines in the crosstab (1 row, 2 columns).

Drag and drop Product-line into the table. Choose align left for that field of the table.

Now drag the chart into the left field of the table.

Go to the properties of the chart and click on Master Detail Relationships. A propertie box opens. In here create a new link between Product-line from the Query Crosstab and Product-line from the query Chart.

Now run the report to see the result.
