Plots not showing data

I am plotting 2 figures.

figure 2 is plotting 2 (1,12) arrays.

figure 3 is plotting 2 (1,365) arrays.

for some reason there is no data in the plots despite the limits on the axis being correct.

here is what my code looks like

Month{1}=Electricity(1:744);
Month{2}=Electricity(745:1416);
Month{3}=Electricity(1417:2160);
Month{4}=Electricity(2161:2880);
Month{5}=Electricity(2881:3624);
Month{6}=Electricity(3625:4344);
Month{7}=Electricity(4345:5088);
Month{8}=Electricity(5081:5832);
Month{9}=Electricity(5833:6552);
Month{10}=Electricity(6553:7296);
Month{11}=Electricity(7297:8016);
Month{12}=Electricity(8017:8760);
figure(2);
for i=1:12
    MonthSum(i)=sum(Month{i});
   plot((i),MonthSum(i))
   hold on
end

hold off
z=1;
figure(3)
for j=1:365
    Daily{j}=Electricity(z:z+23);
    z=z+length(Daily{j});
    DailySum(j)=sum(Daily{j});
end
x1=linspace(1,365,365);
    y1=DailySum(:);
    plot(x1,y1);

(same for figure 3)

thanks for the help.

how about this...

clear;
clc;
Electricity=randi(100,8760,1);
Month{1}=Electricity(1:744);
Month{2}=Electricity(745:1416);
Month{3}=Electricity(1417:2160);
Month{4}=Electricity(2161:2880);
Month{5}=Electricity(2881:3624);
Month{6}=Electricity(3625:4344);
Month{7}=Electricity(4345:5088);
Month{8}=Electricity(5081:5832);
Month{9}=Electricity(5833:6552);
Month{10}=Electricity(6553:7296);
Month{11}=Electricity(7297:8016);
Month{12}=Electricity(8017:8760);
figure(2);
for i=1:12
    MonthSum(i)=sum(Month{i});
   plot((i),MonthSum(i),'*')
   hold on
end
hold off

z=1;
figure(3)
for j=1:365
    Daily{j}=Electricity(z:z+23);
    z=z+length(Daily{j});
    DailySum(j)=sum(Daily{j});
end
x1=linspace(1,365,365);
    y1=DailySum(:);
    plot(x1,y1);

Hi Dillon,

It is my understanding that you are trying to plot coordinates of month number and "MonthSum" on x and y-axis respectively.

The plot function, by default plots a line which requires at least two points in the form of vector. You may specify "Marker" type as shown below to plot individual point coordinates:

plot((i),MonthSum(i),"o"); 

You may refer to the following documentation to know more about "Marker" types.

Specify Line Style, Color, and Marker

I hope it helps you.
