Examples with XYValueSeries com.codename1.charts.models.XYValueSeries used on opensource projects

Example 1 with XYValueSeries

use of com.codename1.charts.models.XYValueSeries in project CodenameOne by codenameone.

the class XYValueSeriesTransition method initTransition.

/**
 * Initializes the transition.  This can be overridden by subclasses to
 * provide their own functionality to be executed just before the transition
 * occurs.
 */
@Override
public void initTransition() {
    super.initTransition();
    // Now make sure that there are the same number of values in source and
    // target
    startVals = new XYValueSeries("Start");
    copyValues(series, startVals);
    endVals = new XYValueSeries("End");
    copyValues(cachedSeries, endVals);
}

Example 2 with XYValueSeries

use of com.codename1.charts.models.XYValueSeries in project CodenameOne by codenameone.

the class BubbleChart method drawSeries.

/**
 * The graphical representation of a series.
 *
 * @param canvas the canvas to paint to
 * @param paint the paint to be used for drawing
 * @param points the array of points to be used for drawing the series
 * @param seriesRenderer the series renderer
 * @param yAxisValue the minimum value of the y axis
 * @param seriesIndex the index of the series currently being drawn
 * @param startIndex the start index of the rendering points
