2009-06-27 Thread Stan Schymanski
Sorry, the behaviour I reported is caused by something else. I copied the cell code that produced different plots at every evaluation into a new notebook and got consistent results every time. Even copying and pasting into a new cell got rid of the random behaviour of the axes. Very weird. I t

In this case, I suspect that evaluation at the boundaries themselves is missing. The function I was plotting decreases monotonically with a large slope at the lower boundary, so the y-value at the lower boundary should be the highest value of the plot. I assume that the show boundaries overwri

This makes sense, thanks. The function that made me discover this behaviour does indeed tend towards an infinite slope at the boundary of the range I prescribed. However, I am not sure if I understand correctly. Can it happen that points outside of the range specified by xmin and xmax are eval

Yes, solving # 5448 might solve it all. Thanks for pointing it out. I'm glad mhansen is working on it, although the last post was 3 months ago. Cheers, Stan kcrisman wrote: >> I remember that the axes labelling in plot() has been discussed a >> while ago, but it seems that it still has not been

Would it help to open a ticket for motivation? I noticed another issue, namely that the y-axis range is chosen randomly and the plots look different every time they are evaluated. I remember reading something about this bug a while ago but I don't remember where. Stan William Stein wrote: > O
