Question on lines joining points in ternary plots

I have drawn more than one curve in a ternary plot.

Is it possible to connect the points with more than one curve on a ternary diagram, either by defining which points belong to which curve, or by manually drawing lines between the points?

Also, is it possible to draw a line between two specific points only?

Mark,
Line segments will only be drawn between points that are part of the same curve, and in that case line segments will be drawn between all points. So the only way to do what you want is create new curves consisting of just the points you want line segments between. From your description I think the easiest way to do this will be to copy the data for one curve (Edit>Copy>Data values), then paste. That gives you a duplicate of the original. Then use Edit>Edit data to delete the points you don't want line segments between. Repeat as necessary.

Alternatively, select Edit>Edit Data. Select "new curve". With your mouse click on the location of the first point. Use Ctrl+left click to add more points. With "Snap mouse" checked the X and Y values will be (for ternary plots) rounded to the nearest integer. Unchecked, no rounding is done.

Thank you.
