BinaryBlock, Block, DataBlock

public class BarChartBlock
extends ChartBlock
implements DataBlock

Bar Chart graph.

The following properties are supported, in addition to Chart-generic ones:

• maxdata - Maximum amount of data items to plot (can supersede those specified in the dataspec).
• x_axis_label_format - A FormatPrinter-style format specification for X axis data (eg. "${year,-5T}")
• datasets - Number of data sets to plot in parallel
• dataset_param_N - Name of the dataset-N parameter to be plot (eg. "age")
• dataset_caption_N - Caption to be used for the specified dataset-N parameter (eg. "Subject age")
• dataset_color_N - The color to be used when plotting the dataset-N. It can be specified by spec_id (eg. "red") or RGB integer values ("R,G,B" or "R-G-B" where R, G and B are between 0 and 255)
• x_axis_title - Label for the X axis
• y_axis_title - Label for the Y axis

Method Detail

init

public void init()
          throws info.informatica.doc.DocumentFormatException

Description copied from class: AbstractBlock

Arranges the block for printing. This method must be called before printing.

Note that blocks implementing NativeBlock must also call initRender(), after init().

This method needs to be called only once, typically before generating the data to be able to check for configuration errors.

Specified by:

init in interface Block

Overrides:

init in class ImageBlock

Throws:

info.informatica.doc.DocumentFormatException - if is unable to initialize due to a syntax or formatting problem.

print

public void print(ReportWriter rw,
                  Dataset rd)
           throws info.informatica.doc.RenderingException,
                  DatasetException

Description copied from interface: DataBlock

Prints a Dataset object.

Uses the ReportWriter object to draw an object representation of the printed data.

Specified by:

print in interface DataBlock

Overrides:

print in class ChartBlock

Parameters:

rw - the ReportWriter object.

rd - the dataset.

Throws:

info.informatica.doc.RenderingException - if a problem occurred when rendering the block.

DatasetException - if there was a problem using the data.
