net.sourceforge.chart2d.PieArea
| PieArea | | final class PieArea extends Area (Code) | | A container for many variables and components relating to a pie area.
A pie area is the area that contains only the pie of a pie chart. It doesn't
have a legend.
Features:
Allows for charting both floats and int values. Works fine even if all
values are zero. Does not accept negative values. Outputs center points
of sectors so that labels can be drawn into the sectors, touching these
points. Outpouts how many sectors are in each quarter of the pie, so that
appropriate placement of labels can be decided. The first datum in the
data set will be the first sector beginning from the angle of 135 degrees and
ending somewhere clockwise to it It will have the first color in the
colors set. The remaining sectors are laid out similarly, clockwise.

| PieArea | | PieArea()(Code) | | Creates a pie area with the default values.
|

The colors of the lines. |
| getDataset | | final float[] getDataset()(Code) | | Returns the raw numbers to represent by the pie.
The raw numbers to represent by the pie. |

| getNumSectors | | final int getNumSectors()(Code) | | Returns this property.
The number of sectors in this pie. |
| getNumSectorsInQuarters | | final int[] getNumSectorsInQuarters()(Code) | | Returns this property. This property allows figuring out where to place
labels if one wants to label this pie, more than is provided by the legend
in PieChartArea. One can use a
HorizontalTextListArea for the TOP and BOTTOM labels; and a
VerticalTextListArea for the LEFT and RIGHT labels.
This information helps them figure out how many and which labels belong in
each text list.
The number of sectors in the quarters. Actually, the number ofcenter points of sectors in this quarter. Quarters are defined as follows:TOP = 135 to 45, LEFT = 45 to 315, BOTTOM = 315 to 225, RIGHT = 225 to 135. |
| getOutlineSectors | | final boolean getOutlineSectors()(Code) | | Returns whether the sectors should have a thin outline.

| getPointsInSectors | | final Point[] getPointsInSectors()(Code) | | Returns a point in each sector at the depth specified by
setSectorsPointDepthRatio(float).
Point[] The points inside the sectors. |
| getPointsOutSectors | | final Point[] getPointsOutSectors()(Code) | | Returns a point in out of each sector at the location indicated by

getPointsInSectors() method are.
The ratio on the radius of the circle. |
| paintComponent | | final void paintComponent(Graphics2D g2D)(Code) | | Paints all the components of this class. First all variables are updated.
Parameters:
g2D - The graphics context for calculations and painting. |
| resetPieAreaModel | | final void resetPieAreaModel(boolean reset)(Code) | | 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 maxsizing. |
| setColors | | final void setColors(Color[] colors)(Code) | | For input of the color of each sector that represents a datum of the data
set. Array element i is sector i, clockise from degree 135.
Parameters:
colors - The colors of the sectors. |
| setCustomSpaceSize | | final void setCustomSpaceSize(boolean customize, Dimension size)(Code) | | Sets the "minimum" size of the pie directly. If the minimum is too
large, then the size will be the pie's maximum size.
Parameters:
size - The number to multiply to get the minimum size. |
| setDataset | | final void setDataset(float[] values)(Code) | | For input of the raw numbers to represent by the pie. Array element i
is sector i, clockwise from degree 135.
Parameters:
values - The raw numbers to represent by the pie. |
| setLightSource | | final void setLightSource(int source)(Code) | | Sets from which direction the light is coming for shading of the pie sectors.
Parameters:
source - The direction of the light. |
| setOutlineSectors | | final void setOutlineSectors(boolean outline)(Code) | | Indicates whether the sectors should have a thin outline.
Parameters:
outline - If true, then the outline exists. |
| setOutlineSectorsColor | | final void setOutlineSectorsColor(Color color)(Code) | | Indicates the color of the sectors outline if it exists.
Parameters:
color - The color for the outline. |
| setPiePrefSizeModel | | final void setPiePrefSizeModel(int size)(Code) | | Sets the model size of the pie. When initially drawn, the pie will be
at least this size, if this size is less than the max space size of this
area. After that and if magnificying, the pie size will be applied to the
size ratios.
Parameters:
size - The model size of the pie. |
| setSectorGapPointRatio | | final void setSectorGapPointRatio(float ratio)(Code) | | Determines how far out of the sector the points from the
getPointsOutSectors() method are.
Parameters:
ratio - The ratio on the radius of the circle. |
| setSectorPointDepthRatio | | final void setSectorPointDepthRatio(float ratio)(Code) | | Determines how far into the sector the depth of the points from the
getPointsInSectors() method are.
Parameters:
ratio - The ratio on the radius of the circle. |
| updatePieArea | | final void updatePieArea()(Code) | | Updates this parent's variables, and this' variables.
