 Jul2 comment Best way to illustrate Keplers 2nd law with tikz Not that anything stands against saving the path in a macro (TikZ does support this) you can also save it as a style with the help of insert path: the saveuse path key. Might be helpful in some cases. :) Jul2 revised hyperbola curve and its arc added 752 characters in body Jul2 answered hyperbola curve and its arc Jul2 comment Drawing a straight line over a coordinate Related: Confused at + and ++ in TikZ Jul2 comment Drawing a straight line over a coordinate No. The “pen” is still at (x1+x2,y1+y2), but further calculation of relative coordinates are done from (x1,y1). See my comments to Confused at + and ++ in TikZ. What I meant with my previous comment also is that ()+() is not seen as one entity (but works for move-tos and thus as a path-start) but simply to different operations. Jul2 comment Usage of final option with package animate @MHaaZ Happens to everybody. :) (My first sentence is obviously a joke.) Interestingly enough, I couldn’t compile your example with draft or final. Jul2 comment hyperbola curve and its arc What do you know about the “bow”? Is it a simple arc (fixed radius) or can it approximated by one? Is it sine? You can also plot it directly with TikZ. Jul2 answered Using \ifdraft like \iffalse Jul2 comment Iterate over certain matrix cells You need to use \pgfmathtruncatemacro otherwise you have a another . in the output: (m-1-0.0.south) (TikZ parses that as node name m-1-0 and anchor 0.south which it tries as an angle since no anchor is named 0.south. Besides that, there is a spurious { right before the relative coordinate and \itemtimesfour should be \itimesfour. Jul2 comment Can't use 'equal' in tikz-cd There is no need to update packages yourself, manually or by removing old files first. Simply use the updating manager from your distribution. Take a look at How do I update my TeX distribution? Jul2 answered Usage of final option with package animate Jul2 comment Create a Shmoo plot with pgfplots/tikz After reconsidering this might be something for the mesh or the surf plot, though it seems the colors of the z values are assigned to an area between coordinates and not an area around coordinates. Jul2 comment Create a Shmoo plot with pgfplots/tikz This could be something that can be easily coded for TikZ direct (e.g. a \matrix) or even a simple tabular. Especially if the x and y values are discrete like that. How does the input look like? Jul2 revised Create a Shmoo plot with pgfplots/tikz deleted 17 characters in body Jul1 comment Drawing a straight line over a coordinate Alternatively, you can say ([shift={(0:2cm)}] cor) (or xshift=2cm in this case) without calc. It might be helpful to note that a simple coordinate without --, to, edge, .., etc. is simply a move-to operation. So (x1,y1) + (x2,y2) will first move to (x1,y1) then to (x1+x2,y1+y2).
