class LBGraphArea

extends GraphArea

The area that the x axis and y axis attach to, and in which bars, lines, or dots are painted to represent the data set. The "LB" in the name of this class stands for Labels Bottom. This graph should always be used when the data descriptors for the the graph are located on the bottom. Data descriptors have values such as September and November, and not like 0 or 50. Features:
Provides bordering functionality. Allows lines to be painted that match up with y axis and x axis tick marks in order to know where the bars, dots, or plot lines are in relation to the y axis values. Supports vertical bar graphs, line charts, and scatter charts (dots), and any combintation thereof. If a bars are present in any graph, then it is highly recommended that the GraphArea method, allowComponentAlignment be passed the value of false. This will ensure that all the bars are visible on the graph. For graphs that do not have bars present, the opposite is advised. The GraphArea method should be passed the value of true. This provides a more intuitive representation of the data.

Constructor Detail

LBGraphArea

LBGraphArea()

Creates a graph area with GraphArea's default values. Default values: resetLBGraphAreaModel (true);

Method Detail

getPrefWidth

int getPrefWidth(int numSets,
                 int numCats,
                 int numCompsPerCat)

Does a quick calculation of the preferred width of the graph.

Parameters:

numSets - The number of data series.

numComps - The number of data categories per series.

numCompsPerCat - The number of data per series, per category.

Returns:

The preferred width.

getLBGraphAreaNeedsUpdate

boolean getLBGraphAreaNeedsUpdate()

Indicates whether some property of this class has changed.

Returns:

True if some property has changed.

resetLBGraphAreaModel

void resetLBGraphAreaModel(boolean reset)

Resets the model for this class. The model is used for shrinking and growing of its components based on the maximum size of this class. If this method is called, then the next time the maximum size is set, this classes model maximum size will be made equal to the new maximum size. Effectively what this does is ensure that whenever this objects maximum size is equal to the one given, then all of the components will take on their default model sizes. Note: This is only useful when auto model max sizing is disabled.

Parameters:

reset - True causes the max model size to be set upon the next max sizing.

updateLBGraphArea

void updateLBGraphArea()

Updates this parent's variables, and this' variables.

paintComponent

void paintComponent(java.awt.Graphics2D g2D)

Paints all the components of this class. First all variables are updated.

Overrides:

paintComponent in class GraphArea

Parameters:

g2D - The graphics context for calculations and painting.
