Example 1 with TimelineChart

use of org.gephi.timeline.api.TimelineChart in project gephi by gephi.

the class Sparkline method getImage.

public BufferedImage getImage(TimelineModel model, int width, int height) {
    double newMin = model.getCustomMin();
    double newMax = model.getCustomMax();
    TimelineChart newChart = model.getChart();
    if (chart == null || newMax != max || newMin != min || image.getWidth() != width || image.getHeight() != height || newChart != chart) {

        if (chart != null) {
            double minX = chart.getMinX().doubleValue();
