Is possible to dynamically resize the area occupied by the chart depending on the amount of information (variations of a category) to be displayed on it ?
One way of achieving this is to use a chart embedded inside another data region’s group. For instance, you could use a list data region with a detail group based on the following expression:
=Ceiling(RowNumber(Nothing)/20)
This will result in one group for every twenty detail rows. Embedding a chart inside that list will create chart instances at runtime for every twenty rows.
If you are looking for an inline bar visualization of data, you can use two different implementation approaches:
* Embedded image with dynamically calculated padding.
* Embedded bar chart with a calculated y-axis maximum value.
Both of these approaches are implemented side-by-side in the TableInlineCharts sample report attached to the bottom of this posting. The sample report is based on the Northwind database.
Note: the embedded image approach dynamically calculates the right padding values of the rectangle that contains the image and thereby achieves bars of variable length!
