Marking points selected on the graph instantly while using ginput()

Hi,

Is there a way in the code below to mark and show selected points on the graph instantly while selecting them? (48 -52 code lines)

clear all;
close all;
% Select the figure you want to digitize
% filename = uigetfile('Select a SPECTRUM file'); %open spec file
filename='Psat_vs_Frequency.png'
% Read image
image=imread(filename);
% Averages the RGB components of the image and plot
imageave=sum(image./size(image,3),3);
screen_size = get(0,'ScreenSize');
f1 = figure(1);
imshow(imageave,[]);
set(f1,'Position',[0 0 screen_size(3) screen_size(4)]);
% Define your axes limits
prompt = {'Enter xmin:','Enter xmax:','Enter ymin:','Enter ymax:'};
dlg_title = 'Input parameters';
num_lines = 1;
def = {'','','',''};
answer = inputdlg(prompt,dlg_title,num_lines,def);
xmin=str2num(answer{1});
xmax=str2num(answer{2});
ymin=str2num(answer{3});
ymax=str2num(answer{4});
% Check if any axis is in log scale
buttonx = questdlg('Is the x-axis in log scale?');
buttony = questdlg('Is the y-axis in log scale?');
% Select xmin, xmax, ymin, ymax
title(['Select xmin = ',num2str(xmin)]);
[x0(1),y0(1)]=ginput(1);                  % Modified on 06/13/2020
line(x0(1),y0(1),'Marker','o','Color','r','MarkerSize',13) % Create Green dot for marking XMIN
title(['Select xmax = ',num2str(xmax)]);
[x0(2),y0(2)]=ginput(1);                  % Modified on 06/13/2020
line(x0(2),y0(2),'Marker','o','Color','r','MarkerSize',13) % Create  Blue dot for marking XMAX
title(['Select ymin = ',num2str(ymin)]);
[x0(3),y0(3)]=ginput(1);                 % Modified on 06/13/2020
line(x0(3),y0(3),'Marker','o','Color','r','MarkerSize',13) % Create  Green dot for marking YMIN
title(['Select ymax = ',num2str(ymax)]);
[x0(4),y0(4)]=ginput(1);                % Modified on 06/13/2020
line(x0(4),y0(4),'Marker','o','Color','r','MarkerSize',13) % Create  Blue dot for marking YMAX
title('Now click on the data points and press enter when done');

% Select npoints on the plot
%[x,y]=ginputRed();                   % Modified on 06/13/2020


[x, y] = ginput();
 
line(x,y, 'Marker','+','Color','r','MarkerSize',13)

% Coordinate transformations
if strcmp(buttonx,'No')==1;
    output(:,1)=[(x-x0(1))/(x0(2)-x0(1))].*(xmax-xmin)+xmin;

        output(:,1)=exp([(x-x0(1))/(x0(2)-x0(1))].*log(xmax/xmin)+log(xmin));
    end
end

    output(:,2)=[(y-y0(3))/(y0(4)-y0(3))].*(ymax-ymin)+ymin;

    end
end

% Save results
button = questdlg('Do you want to save the digitized data as a txt file?')
if strcmp(button,'Yes')==1
    prompt = {'Write file name without extension:'};
    dlg_title = '';
    num_lines = 1;
    def = {''};
    answer = inputdlg(prompt,dlg_title,num_lines,def);
    dlmwrite([answer{1},'.txt'],output,'\t');
end

Thank you,
