Graded beds in lithology track: PSICAT 1.2.0 #13

Open jllancaster opened 3 months ago

jllancaster commented 3 months ago

It appears that the feature allowing representation of a graded bed graphically in the lithology column by assigning different grain sizes to the top and bottom of the bed is now called the lithology (ANDRIL) column. The new CSD lithology column with grain size set in the grain size column does not appear to allow for representation of a graded bed. How does CSD represent graded beds with the new default lithology column? Similar to below?

If you're looking for a way to draw an oblique line from a Lithology interval's top-right to base-right, there is no way to do so at present. I would recommend reverting to the legacy (Andrill) Lithology column in that case, but that comes with other caveats. The column persists in 1.2.0 primarily to preserve compatibility with older projects. We do not suggest using it for new projects.

Your pictured approach of using increasingly larger Grain Size intervals to increment the width of corresponding Lithology intervals certainly works, as long as you don't mind the "stepped" look!

That said, our intention for representing graded beds in 1.2.0 was to use the "Graded bedding, normal/reverse" options in the Bedding column. Creating such a Bedding interval will not affect the visual appearance of corresponding Lithology intervals. If there is sufficient interest, we might consider going down that road, but inter-column interactions between two columns (Lithology and Grain Size) is already a bit complex: adding a third (and inevitably fourth, fifth...) column to that stew could present challenges both visually and computationally.
