How to add a name to Matlab figure's title bar?

1. How to add a name to the Matlab figure's title bar? For example, Figure 1: Time of the year vs. Temperature.

figNum = 1;
figure(figNum)
set(figNum, 'Name', 'Time of the year vs. Temperature');

How to load the Matlab figure and extract data from the figure?

% To load figure

h = hgload('RectangularChipShape.fig')


get(h) % lists all the properties linked to this class
set(h) % lists all the properties that can be configured


Few examples:

set(gca,'fontsize',26);

hline = findobj(gcf, 'type', 'line');
hData = findobj(gcf, 'type', 'data');
set(hline,'LineWidth',4)
set(hline,'LineStyle',':')

idx = [4 5];
set(hline(idx),'Marker','*')


%To extract the data from the figure

axesObjs = get(h, 'Children'); %axes handles
dataObjs = get(axesObjs, 'Children'); %handles to low-level graphics objects in axes


objTypes = get(dataObjs{2});
xdata = get(dataObjs{2}, 'XData'); %data from low-level grahics objects
ydata = get(dataObjs{2}, 'YData');

%To extract data from Surf/Mesh plot
m = magic(10);

figure; h1 = mesh(m); % works for 'surf' also

h12 =gcf; % returns the figure number h1Children = get(h12,'Children');
h1Chotas = get(h1Children,'Children'); % this is equal to h1
xD = get(h1Chotas,'xdata')
yD = get(h1Chotas,'ydata')
zD = get(h1Chotas,'zdata'

How to save Matlab graphs/plots with high resolution/quality (suitable for publications)?

Use the export-figure file from:

http://www.mathworks.com/matlabcentral/fileexchange/23629-exportfig

Examples can be found at:

https://sites.google.com/site/oliverwoodford/software/export_fig


Other settings:

% Colour adjustmentsset(gcf, 'Color', 'w'); %background outside the plot
set(gca, 'Color', 'w'); %background of the plot

% Set figure format - Size
% set(gcf,'Position',[xpos ypos scale*width scale*height])
set(gcf, 'Position', [100 100 150 150])
%or,
scrsz = get(0,'ScreenSize'); %returns the screen size
set(gcf, 'Position', [0 0 0.85*scrsz(3) 1*scrsz(4)]);

% Saving figure using export_fig
figName = [fName(1:end-4) '.png'];

saveas(gcf, figName);
export_fig(figName);

% Example:

function [] = SaveAndExportFigure(figName)
set(gcf, 'Color', 'w'); %background outside the plot
set(gca, 'Color', 'w'); %background of the plot
scrsz = get(0,'ScreenSize');
set(gcf, 'Position', [0 0 0.85*scrsz(3) 1*scrsz(4)]);
saveas(gcf, figName);
export_fig(figName);
