Hi
I would like to plot f(x,y)=1/(x?+y?) with maxima, but I have a problem. At (0,0), I have a giant peak to ~2e30 which erases all the details in the other part of the graph.
I thought about smthg like f(x,y):=(if (x^2+y^2)>0.01 then 1/(x^2+y^2) else 0), but :
1. it is ugly.
2. the plot presents now 4 peaks due to the discretisation of the plan.
I searched in the doc, there quantities about very complicated things like write a title in curve (very cute&usefull ...), but nothing about "simply" limit the z-axis.
Sorry for this prehistorical English, but like all the other French people, I don't know well foreign languages ...
Regards,
Sebastien
