How to specify Markers in Octave/Matlab Plot?
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)
