How to make peaks of a plot smooth in MATLAB?

I want to make the edges shown in the figure smooth.

I have used interpolation but I want to makes these edges more smooth. Please help me.Below is my code.

clear all; close all; clc;
x= [0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1];
y1 = [0    0.0833    0.1583    0.2167    0.1500    0.3250    0.3750    0.3000    0.5917    0.3750    0.5000];
y2=  [ 0         0    0.0167    0.0750    0.1000    0.0917    0.1167    0.1583    0.1083    0.2000    0.1833];

figure(1)
plot (x,y1)
hold on
plot (x,y2)
figure (2)
Xi = 0:0.005:1;
Yi = pchip(x,y1,Xi);
plot(Xi,Yi)
hold on
Yj = pchip(x,y2,Xi);
plot(Xi,Yj)

If you want a smoother interpolation result, spline can be a better way for you.

plot (x,y1,'o')
hold on
plot (x,y2,'o')

Xi = 0:0.005:1;
Yi = pchip(x,y1,Xi);
Yi_spline = spline(x,y1,Xi);
h(1) = plot(Xi,Yi,'-','color',lines(1));
h(2) = plot(Xi, Yi_spline, '--', 'col
