```Show[Plot[x^2, {x, -5 , 10}],
RegionPlot[0 < y < x^2, {x, 2, 7}, {y, 0, 100}]]

Plot[{x^2, Piecewise[{{x^2, 2 < x < 7}}]}, {x, -5 , 10},
Filling -> {2 -> Axis}]

Hello everyone,

I'd like to fill a plot down to the x-axis but restrict the fill to lie between two x values, and am not sure how to do it.  For example, if I plot a parabola f[x] = x^2, with x in the range =E2=88=9210 to 10, I'd like to be able to fill to the x-axis between x = 2 and x = 7, essentially creating a filled column.  Is there any way to do that?

Regards,

Gregory
