I disagree. Thinking that putting "RTX_" 12-19 times on an overly crowded graph is at all reasonable is simply a complete lack of proficiency in presenting data, and a lesser oversight in thinking things thru. Which is different from, say, gathering data (the reviews here are very good, imho!). This is a simple, and very specific, lack of skill in presenting information, which can be easily addressed if the person so chooses, and a complete failure to recognize the issue (which is a perceptual issue, which can be trickier). Up till now, I was being (I think) somewhat polite about it, despite the egregious claims, but...eh. The argument made is laughably indefensible, and an appeal to authority for a provably incorrect defense is hardly better. Sayin "it can't be done" and "it's a software problem" is simply incorrect. The nice person can, and would benefit from, learning to present data better. Or, they can just keep the status quo. But claims of "not my fault" are just wrong.
You, of course, can have a nice day.
