For my project i need to to a regression with a bunch of data I've gathered. I have 7 variables and i did the regression in excel and got the ANOVA and everything. But i don't know how to plot all of these in one graph. Note that 5 of my variables are dummy variables and can only take on 1 or 0 as values. Basically how do i plot:

y = b0 + b1x1 + b2x2 + .... +b7x7

in excel on one 2d graph, if its even possible?

If anyone knows how to do this in any other software such as R, its acceptable as well.
