I have to plot a figure like this.

Please help. Below is my code.

Real Coefficient= [0.0723, -11.0000, 0.001, 0.0011, 0.0012, 0.0013, 0.0014, 0.0015, 0.0016, 0.0017, 0.0018, 0.0019, 0.00110, 0.00111, 0.00112, 0.00113, 0.00114, 0.00115, 0.00116, 0.00117, 0.00118, 0.00119, 0.00120, 0.00121, -1, -1] ;

Predicted Coefficient= [-0.9265, -11.0000, 0.001, 0.0011, 0.0012, 0.0013, 0.0014, 0.0015, 0.0016, 0.0017, 0.0018, 0.0011, 0.0011, 0.0011, 0.0011, 0.0011, 0.0011, 0.0012, 0.0012, 0.0012, 0.0012, 0.0012, 0.0012, 0.0012, -1, -1] ;

close all; clear all; clc;
data= [0.0723, -0.9265;
      -11.0000, -11.0000;
       0.001, 0.001
       0.0011, 0.0011
       0.0012, 0.0012
       0.0013, 0.0013
       0.0014, 0.0014
       0.0015, 0.0015
       0.0016, 0.0016
       0.0017, 0.0017
       0.0018, 0.0018
       0.0019, 0.0011
       0.00110,0.0011

       0.00113,0.0011
       0.00114,0.0011
       0.00115,0.0012
       0.00116,0.0012
       0.00117,0.0012
       0.00118,0.0012
       0.00119,0.0012
       0.00120,0.0012
       0.00121,0.0012
      -1.0000,-1.0000
      -1.0000,-1.0000];
dy=0.2;
f=figure;
t=tiledlayout("flow");
nexttile(t);
h=scatter(x,y,100,'filled','MarkerEdgeColor','k');
C = jet(numel(x));
h.CData = C;
set(gca, 'colormap', C)
colorbar()

why not use normal plot command?

RealCoefficient= [0.0723, -11.0000, 0.001, 0.0011, 0.0012, 0.0013, 0.0014, 0.0015, 0.0016, 0.0017, 0.0018, 0.0019, 0.00110, 0.00111, 0.00112, 0.00113, 0.00114, 0.00115, 0.00116, 0.00117, 0.00118, 0.00119, 0.00120, 0.00121, -1, -1] ;

PredictedCoefficient= [-0.9265, -11.0000, 0.001, 0.0011, 0.0012, 0.0013, 0.0014, 0.0015, 0.0016, 0.0017, 0.0018, 0.0011, 0.0011, 0.0011, 0.0011, 0.0011, 0.0011, 0.0012, 0.0012, 0.0012, 0.0012, 0.0012, 0.0012, 0.0012, -1, -1] ;

plot(PredictedCoefficient,'or')

hold on;

plot(RealCoefficient,'+k');

xlabel('Term ID');

ylabel('V');

legend('Predicted Coeff.','Real Coeff.')
