I want to write a MATLAB code to draw the intensity of a LED. I have a data set of angle (20, 40, 60, 80, 110, 130, 150) and its lux are (14, 20, 26, 30, 27, 21, 13) respectively. The height is 1m fixed. The graph should be similar to the above where it also shows the intensity bar. The code is above (I COPIED THIS FROM SOMEONE ELSE ONLINE. THIS IS NOT MY CODE OR PLOT). Please help with MATLAB codes also!
