嗨,我正在尝试使用此库绘制图表,但其条目静态如下:
LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
new DataPoint(0, 1),
new DataPoint(1, 5),
new DataPoint(2, 3),
new DataPoint(3, 2),
new DataPoint(4, 6)
});
graph.addSeries(series);

我如何解决这个接受前的问题.在运行时创建的列表视图元素?基本上我想要这样的东西:
for (int i = 0; i < list.size(); i++) {
LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
new DataPoint(i, list.getElement()),
});
}

尝试这样的事情:
DataPoint[] dataPoints = new DataPoint[list.size()]; // declare an array of DataPoint objects with the same size as your list
for (int i = 0; i < list.size(); i++) {
// add new DataPoint object to the array for each of your list entries
dataPoints[i] = new DataPoint(i, list.getElement()); // not sure but I think the second argument should be of type double
}
LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(dataPoints); // This one should be obvious right? :)
