Just suggestion for plotting constants on HP Prime in Function Application.
I do not know if that is possible, but why not introduce in function definition the “WHERE” option, eg. F1(X)=X|(X=const) and plot the vertical line at X=const. Just thinking.

“WHERE” can currently be used in the Function app; F1(X)=(K+COS(K))|(K=2), for example, will plot as F1(X)=2+COS(2). (That said, how the Function app deals with “|(X=…)” in definitions of functions to be plotted should be adjusted.)

Being able to switch the independent variable for some of the functions could allow one to plot, e.g., F1(Y)=const, but would also require changes in other places (such as the Numeric view, but also the Fcn choices in Plot views). This could become a bit of a can of worms… (And, from a certain viewpoint, the ”X” is a placeholder in F1(X) — it is, simply, the name of the variable to be used in the definition, and the Plot view works with functions from R to R [the name ”X” is bound within the definition and not visible from outside the definition].)

Perhaps some tick customization options could get you what you want: being able to add specific X values to a list (in Plot Setup) that would then be dashed lines in plot views. Comments?
Hello,
I've never tried "WHER" in Function Application. It is nice to know.
Thank you.
