How to display data on plot without overlapping displayed data.

I've been trying to display the data that my plot is displaying, but my problem is certain data is overlapping the other one.

Is there a way were I can display the numbers without them covering each other?

% Get the data and construct the polynomial interpolant.
n = 11; ind = transpose([1:11]);
x  = -4+8*(ind-1)/(n-1);
x2 =  4*cos((pi*(2*ind-1))/(2*n));
y  =  exp(-x.^2);
c  = interpnewt(x,y);
%c2 = interpnewt(x2,y);
plot(x, y, 'rx')
hold on
z  = transpose(linspace(-4,4,500));
p  = hornernewt(c,x,z);
%p1 = hornernewt(c2,x2,z);
set(gca, 'fontsize', 9)
fp = plot(z,p)
strValues = strtrim(cellstr(num2str([round(x(:),3,'significant') round(y(:),3,'significant')],'(%df3,%df3)')));
text(x,y,strValues,'HorizontalAlignment','center','FontSize',14);
fp(1).LineWidth=3;
