public abstract class ChartDataset
extends ChartObj

This is the abstract base class for all dataset classes used by the plot routines in this software. A dataset class encapsulates x- and y-data values that are to be used as source of chart information. Copies of the original data arrays are stored. The original source data can be deleted once the dataset is created. If you want to make any changes to the data, you must change the data in the dataset, not the original source data.

Field Summary

boolean	initialCondition Specifies that the buffer has not been incremented yet.
int	markLookaheadLimit Specifies that mark read ahead limit used in the Dataset ReadAsResource routines

Method Detail

calcNearestPoint

public abstract boolean calcNearestPoint(PhysicalCoordinates transform,
                                         ChartPoint2D testpoint,
                                         int nmode,
                                         NearestPointData nearestpoint)

This method abstract is the prototype for a data point nearness test. It compares a test point against all of the xy points in a dataset and calculates which point in the dataset is nearest the test point. The nearness test has many different forms: Nearness Mode Constant Description FNP_X nearest x FNP_Y nearest y FNP_DIST shortest distance FNP_NORMX nearest normalized x FNP_NORMY nearest normalized y FNP_NORMDIST shortest normalized distance Subclasses should this method.

Parameters:

transform - The PhysicalCoordinates coordinate system associated with these points.

testpoint - The test point for the nearness calculation.

nmode - Specifies the algorithm used in the nearness calculation.

nearestpoint - Returns the xy values of the dataset point nearest the test point.

Returns:

Returns true if a valid data point is found and returned.

copy

public void copy(ChartDataset source)

Copies the source dataset.

Parameters:

source - The source dataset object.

errorCheck

public int errorCheck(int nerror)

Checks the current dataset object for common errors.

Overrides:

errorCheck in class ChartObj

Parameters:

nerror - Current error state.

Returns:

Returns an error code.

getAutoCompressDatasetModeX

public int getAutoCompressDatasetModeX()

The compression type for the x-values. Use one of the data compression type constants: DATACOMPRESS_NONE (returns a dataset containing the points in the specified range, no compression), DATACOMPRESS_SKIP (sample the dataset every interval points), DATACOMPRESS_AVERAGE (use the average x- and y-value in each interval), DATACOMPRESS_MIN (use the minimum x- and y-value in each interval), DATACOMPRESS_MAX (use the maximum x- and y-value in each interval), and DATACOMPRESS_MINMAX (use the minimum and maximum x- and y-value in each interval). The DATACOMPRESS_MINMAX compression type is best used when the compressed data values number more than 1000, where adjacent data values in the rendered chart differ by one horizontal pixel or less. The DATACOMPRESS_MINMAX compression type will guarantee that the chart displays the same minimums and maximums as the original dataset.

getAutoCompressDatasetModeY

public int getAutoCompressDatasetModeY()

Use one of the data compression type constants: DATACOMPRESS_NONE (returns a dataset containing the points in the specified range, no compression), DATACOMPRESS_SKIP (sample the dataset every interval points), DATACOMPRESS_AVERAGE (use the average x- and y-value in each interval), DATACOMPRESS_MIN (use the minimum x- and y-value in each interval), DATACOMPRESS_MAX (use the maximum x- and y-value in each interval), and DATACOMPRESS_MINMAX (use the minimum and maximum x- and y-value in each interval). The DATACOMPRESS_MINMAX compression type is best used when the compressed data values number more than 1000, where adjacent data values in the rendered chart differ by one horizontal pixel or less. The DATACOMPRESS_MINMAX compression type will guarantee that the chart displays the same minimums and maximums as the original dataset.

getAutoCompressDivisor

public int getAutoCompressDivisor()
