f[x_] = Exp[-x/10];

ParametricPlot[
 {10*Log[10, x], NIntegrate[f[t], {t, 0, x}]},
 {x, 1, 100},
 AspectRatio -> 1,
 PlotRange -> All]

Hi, 
 
        I need to plot an Integral, that i need to solve numerically. I need to plot 10Log10[x] versus result of integral. If i plot

      Plot[nIntegrate[<my func here, in x>],{x,100,1,-1}]

   is easy, but the plot is wrong. i need to do 10Log10 of x, not only x. But if i plot

      LogLinearPlot[nIntegrate[<my func here, in x>],{x,100,1,-1}] the plot is a Log in x, but the values that appear isn't in log...How can i do this? i search alot in google, in help, in anywhere...What i'm doing wrong?

 Thanks a lot

Breno
