I'm trying to construct a graph that represents a set impulse delta functions by creating a set of line segments with the following code:
series.appendData(new DataPoint(0,0), true, 30);
series.appendData(new DataPoint(0,1), true, 30);
series.appendData(new DataPoint(0,0), true, 30);
series.appendData(new DataPoint(1,0), true, 30);
series.appendData(new DataPoint(1,1), true, 30);
series.appendData(new DataPoint(1,0), true, 30);
series.appendData(new DataPoint(2,0), true, 30);
However, each vertical line segment beyond the first does not plot on the graph as illustrated in the attached screenshot.
Perhaps you have some insight as why the vertical line segments are not being plotted.
