+#X text 25 13 Drawing instructions can be dynamically turned on and
+off \, either globally for all data of a given template \, or locally
+according to a data field. In this example the "drawcurve" instruction's
+arguments contain the leading flag "-v b" meaning that its visibility
+is turned on and off by the field b.;
+#X text 25 111 To turn a drawing instruction on and off globally \,
+send a number to its inlet. By default drawing instructions are initially
+visible \, unless given the "-n" flag.;
+#X text 21 169 Arrays have the additional possibility of turning on
+and off drawing instructions for their individual points as scalars.
+Use "-vs z" to make the variable z control this.;
