Problem with Sgrayplot/plot

[FOURNIER Elisabeth]

Hello,


I have a problem with Sgrayplot and plot.

1. With Sgrayplot, I obtain a map for the data (carto.dat)
2. I want to plot just one point with a color. (Point [80,80]) with the plot 
or plot2d function.

Resultat : The point appears in color, but also a isoline ([x~10-20, 
y~10-20]) appears with the same color.

Why? What to do?
Thanks for your help

Elisabeth Fournier
