To change a line texture part way through a line, you need to draw a different line for each part that has a different texture. For example,
idx1 = find(x < -0.8);
idx2 = find(-0.8 <= x & x <= 0.8);
idx3 = find(0.8 < x);
idx1t = [idx1(:); idx2(1)];
idx2t = idx2;
idx3t = [idx2(:); idx3(1)];
plot( x([idx1t), y(idxt), '-');
hold on
plot(x(idx2t), y(idx2t), '--');
plot(x(idx3t), y(idx3t), '-');
The extra work with the *t variables is to allow the segments to join up.
