Overview
Let’s learn the steps involved to specify markers in the Octave/Matlab plot command with attributes like edge color, face color, and marker size, etc. The octave script with comments shown below to plot the time vs velocity graph.
Octave Script
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Sample Octave Plot
% LineWidth = 7.0
% Plot line color = Blue
% MarkerEdgeColor = Green
% MarkerFaceColor = Red
% MarkerSize = 30
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
gravity=9.81 %m/s^2
mass=60 %kg
c=0.35
%time vector
time=linspace(0,30,30);
%Calculate v
velocity=sqrt(gravity*mass/c)* tanh(sqrt(gravity*c/mass).*time);
%Plot graph
figure
%plot command
plot(time,velocity,':bo','LineWidth',7.0,...
'MarkerEdgeColor','g',...
'MarkerFaceColor','r',...
'MarkerSize',30)
xlabel('time')
ylabel('velocity')
title('Sample Plot')
Plot with Marker
%plot command
plot(time,velocity,’:bo’,’LineWidth’,7.0,…
‘MarkerEdgeColor’,’g’,…
‘MarkerFaceColor’,’r’,…
‘MarkerSize’,30)
