List of java2DToValue() Examples

Examples of java2DToValue()

com.positive.charts.axis.ValueAxis.java2DToValue()
Converts a coordinate in Java2D space to the corresponding data value, assuming that the axis runs along one edge of the specified dataArea. @param java2DValue the coordinate in Java2D space. @param area the area in which the data is plotted. @param edge the edge along which the axis lies. @return The data value. @see #valueToJava2D(double,Rectangle2D,RectangleEdge)
org.jfree.chart.axis.DateAxis.java2DToValue()
Translates a Java2D coordinate into the corresponding data value. To perform this translation, you need to know the area used for plotting data, and which edge the axis is located on. @param java2DValue the coordinate in Java2D space. @param area the rectangle (in Java2D space) where the data is to beplotted. @param edge the axis location. @return A data value.
org.jfree.chart.axis.LogAxis.java2DToValue()
Converts a Java2D coordinate to an axis value, assuming that the axis covers the specified edge of the area. @param java2DValue the Java2D coordinate. @param area the area. @param edge the edge that the axis belongs to. @return A value along the axis scale.
org.jfree.chart.axis.NumberAxis.java2DToValue()
Converts a coordinate in Java2D space to the corresponding data value, assuming that the axis runs along one edge of the specified dataArea. @param java2DValue the coordinate in Java2D space. @param area the area in which the data is plotted. @param edge the location. @return The data value. @see #valueToJava2D(double,Rectangle2D,RectangleEdge)
org.jfree.chart.axis.ValueAxis.java2DToValue()
Converts a coordinate in Java2D space to the corresponding data value, assuming that the axis runs along one edge of the specified dataArea. @param java2DValue the coordinate in Java2D space. @param area the area in which the data is plotted. @param edge the edge along which the axis lies. @return The data value. @see #valueToJava2D(double,Rectangle2D,RectangleEdge)
