+ * This is a single point (1D) dataset, all points are of the type (0, y1), (1,
+ * y2), (2,  y3)... Where the X-value is implicitly incremented. This is useful
+ * for example for barcharts, where you could fx. use an {@link
+ * Image_Graph_Dataset_Array} datapreprocessor to make sence of the x-values.
