Question

Day	High temperature, C	Low temperature, C
1	30	25
2	32	26
3	34	23
4	29	20
5	31	19
6	30	21
7	25	18

The high and low temperatures of each day in Wichita KS are given in Table. (1 pt) (a) Plot the high temperature for 7 days as a function of day, i.e., high temperature on y-axis, and day # on x-axis. Use the red, empty square as a marker with the solid line. (b) Plot both the high and low temperature for 7 days as a function of day in the same plot. Use the red, empty square as a marker with the solid line for high temperature, and blue, empty circle as a marker with the dotted line for low temperature.

For Octave/Matlab

Answer 1

a)

Matlab Code:

day = [ 1 2 3 4 5 6 7];
High_temp = [30 32 34 29 31 30 25];
Low_temp = [25 26 23 20 19 21 18];
plot(day,High_temp,'-s','MarkerSize',10,...
'MarkerEdgeColor','red',...
'MarkerFaceColor','red')
xlabel('Day');
ylabel('Temperature');

b) .

Matlab Code:

day = [ 1 2 3 4 5 6 7];
High_temp = [30 32 34 29 31 30 25];
Low_temp = [25 26 23 20 19 21 18];
plot(day,High_temp,'-s','MarkerSize',10,...
'MarkerEdgeColor','red',...
'MarkerFaceColor','red')
hold on
plot(day,Low_temp,'-o','MarkerSize',10,...
'MarkerEdgeColor','blue',...
'MarkerFaceColor','none')
legend('High temperature','Low temperature')
xlabel('Day');
ylabel('Temperature');
