Your reference will be shown as a blue ring-width curve and a black normalized curve based on the P2Yrs method (ref 1).
Your current measurements (not yet saved) or your current .pos file will be plotted on top of your reference curve as a green ring width curve and a
red curve of normalized data, i.e. all curves are shown as in CDendro.
To synchronize the curves, click on the button to the right of the "Offset:-box" above the curves. Current correlation coefficient,
T-value and overlap are then shown as text on top of that button.
At the bottom of the curve diagram you will find correlation coefficients plotted every 10th year and calculated from 20 years long successively overlapping segments.
To change the offset between your measurement curve and the reference (i.e. to shift your curve along the reference curve)
either use the small "arrow-buttons" at the sides of the "Offset:-box" or use
the arrow keys of your keyboard like in CDendro (then first click on the curve diagram to make it focused before pressing an arrow button).
When you move the curves in relation to each other, all correlation values will be automatically updated.
If you click on the curve, the corresponding point within the upper picture will be "selected", i.e. made bold - see point 9 in the picture above.
Correspondingly: If you select one of your points in the upper diagram, a vertical short green line will be drawn across the ring width curve at the corresponding position.
The ring width of that point is shown in the textbox to the left of the "Offset:-box".
If your image has its youngest ring width to the left (instead of to the right as shown above) you may prefer to have your curves
displayed correspondingly. In that case, click the "<--Times-->" button to make the curves plotted the other way.
