i need place label @ right, above of fitted average horizontal rule. have y-coordinate of rule, don't know coordinate of right border of graph. i saw, use at graph 0.5,0.8 syntax, if horizontal rule fixed, isn't. you can use different coordinate systems x , y values. available coordinate systems are: first : value on left , bottom axes. second : value on right , top axes. graph : relative area within axes, 0,0 bottom left , 1,1 top right. screen : relative entire canvas. character : depends on chosen font size. so, if x-value should relative graph, use graph 0.5 , y-value can use first yval : set label @ graph 0.5, first yval+ofs here, yval y-value of horizontal line, , ofs offset in order displace label bit.
