### Code to plot graph in MATLAB

Let’s consider have two dimensional data set where equipment sales are plotted against days of week. Let’s say on day 1, the sales are 4.4 lakh, for day 2 4.5 lakh and so on:

Simply these three lines of code in M-file are enough to plot the table in MATLAB:

x = [1 2 3 4 5 6];

y = [4.4 4.5 5.7 6.3 6.9 8.2];

plot (x,y)

And the output is:

y = [4.4 4.5 5.7 6.3 6.9 8.2];

plot (x,y)

And the output is:

Congrats you plot a graph in MATLAB. But there are few visual problems. There are no lables, one can’t understand what this data set represents. Let’s improve our graph.

x = [1 2 3 4 5 6];

y = [4.4 4.5 5.7 6.3 6.9 8.2];

plot (x,y)

xlabel(‘Days’)

ylabel(‘Sales price in lakh’)

title(‘Sales graph per day’)

y = [4.4 4.5 5.7 6.3 6.9 8.2];

plot (x,y)

xlabel(‘Days’)

ylabel(‘Sales price in lakh’)

title(‘Sales graph per day’)

And the output will be:
