Hello, I am having problems overplotting a symbol on a plot that has a logged axis. For example, when I use the commands below, the symbols are not placed in the appropriate position (I tried uploading my example plot, but I received a permissions error). I would like to put a symbol at the [2,2] position, but that particular symbol is outside of the graphics domain. It is also unclear why the 0.1, 0.2 & 0.5 symbols are on the plot when they are not within the X and Y range of the plot. Will you please tell me what I am doing wrong in the code and how to get the symbols in the correct locations. This is not a problem when both axes are not logged, but it is a problem when only one axis is logged. P = PLOT(FINDGEN(10),FINDGEN(10),/XLOG,/YLOG) S = SYMBOL([0.1,0.2,0.5,1,2], [0.1,0.2,0.5,1,2], 'SQUARE', /DATA,SYM_COLOR=['RED','BLUE','YELLOW','PURPLE','ORANGE'], /SYM_FILLED) Thank you, KH
