Amibroker 6 shows blank chart when formula applied....why does this happen

#1
I ve been using Amibroker 6.2 for quite some time and I ve noticed that many formulas when applied in amibroker displays only blank chart despite the formula is errors free and all the plot commands are properly coded.........I didnt face such problem with Ami5.7 which was a very stable version I believe.........does anyone know why this happens and am I the only one facing this problem...............below are few formulas with which I faced this blank chart problem..........
