Property graphs

The Overview component also displays graphs of the cargo variations in crude properties. Each cargo is plotted as a single point on each graph, together with assay data, and a trend line is displayed to show the general changes in the property being observed. Note that the trend line relates to cargo data only, not to assay data, and will not appear if there are no cargo data points on the graph. Red shading on each graph displays the error range in the measurements calculated from the spread in values of each property. The display shown on the graph is controlled using the Graph Controls section.
