I had this problem a while ago (actually soon after I used the very useful feature of user symbols). The way to get around is to redefine the symbol to nothing in your layout: ## hide user define symbols # symbol-hide line u:mylinesymbol code metapost def l_u_mylinesymbol (expr P) = enddef; endcode Of course it would be better to have symbol-hide working on user-defined symbols but this is still feasible in many cases. Hope that helps. Xavier Le 28/01/2015 10:08, herich@speleodd.sk a écrit :
Hello, I don´t know what I am doing wrong, but if I use something like this in layout: symbol-hide line wall (or show, color, assign), everything works perfect. But, it doesn´t work with "u" , so symbol-hide line u:definedname will make an error with comment - unknown symbol specification. In layout there is a definition of u:definedname, as well as "initsymbol("l_u_definedname"); , outside layout is defined name for legend and everything works well, except symbol-hide (or so) command. Do you have any idea? Thank you Palo
