Examples of org.jfree.chart.axis.AxisState

org.jfree.chart.axis.AxisState
Instances of this class are used to carry state information for an axis during the drawing process. By retaining this information in a separate object, it is possible for multiple threads to draw the same axis to different output targets (each drawing will maintain separate state information).


        // draw the shared axis
        CategoryAxis axis = getDomainAxis();
        RectangleEdge domainEdge = getDomainAxisEdge();
        double cursor = RectangleEdge.coordinate(dataArea, domainEdge);
        AxisState axisState = axis.draw(
            g2, cursor, area, dataArea, domainEdge, info
        );
        if (parentState == null) {
            parentState = new PlotState();
        }
