Hello, If i generate a scatterplot with the keyword magnitude then the colorbar is generated using the Y coordinates not the magnitude. How can i generate a colorbar for the magnitude? Only by hand? Is This a bug? example: t=scatterplot(2.*randomu(seed, 1000), 1.*randomu(seed, 1000), symbol='o', /sym_filled, rgb_table=13, magnitude=5.*randomu(seed, 1000)) ct= colorbar(target=t, /border, orientation=1) note that the colorbar indicates values from 0 to 1 wich is the Y range while it should show values fom 0 to 5. greetings, Ralf
