Answer 3

can you attach your m file for me? I want to try it out on my end

Answer 4

thanks

Answer 5

ok so I forgot that the find function spits out the indices

Answer 6

let me fix

Answer 7

% get snow depth
snow_depth = gcdata2(:,5);

% find the snow depth data in nov 2013 and dec 2013
snow_depth_indices1 = find(year == 2013 & (month == 11 | month == 12));
snow_depth1 = snow_depth(snow_depth_indices1);

% find the snow depth data in jan and feb 2014
snow_depth_indices2= find(year == 2014 & (month == 1 | month == 2));
snow_depth2 = snow_depth(snow_depth_indices2);

% combine the two snow depths
winter13_14_sd = [snow_depth1' snow_depth2'];

Answer 8

now I need to use plotyy right?

Answer 9

you do the same for the snowfall data, then you use plotyy

Answer 10

working and thinking

Answer 11

change `winter13_14_sd` to `winter13_14_sf`

Answer 12

% get snowfall depth
snow_fall = gcdata(:,6);

% find the snowfall data
snow_fall_indices1 = find(year == 2013 & (month == 11 | month == 2));
snow_fall_1 = snow_fall(snow_fall_indices1);

% find the snowfall data
snow_fall_indices2= find(year == 2014 & (month == 1 | month == 2));
snow_fall_2 = snow_fall(snow_fall_indices2);

% combine the two snowfalls
winter13_14_sf = [snow_fall_1' snow_fall_2'];

Answer 13

better

Answer 14

hmm strange, the winter13_14_sf variable has 3 less items than winter13_14_sd

Answer 15

you used the wrong data matrix to get the snowfall

you should use gcdata2

Answer 16

wow... I always do that... lol

Answer 17

they all look the same so I don't blame you

Answer 18

for some reason, it's kicking out 0 values

Answer 19

hmm maybe not, but I'm still coming up with 117 vs 120

Answer 20

winter13_14_sf should have 120 values in it, but for some reason, it only has 117

Answer 21

hmmmm

Answer 22

oh I see what went wrong

you wrote
`snow_fall_indices1 = find(year == 2013 & (month == 11 | month == 2));`
when it should be
`snow_fall_indices1 = find(year == 2013 & (month == 11 | month == 12));`

Answer 23

so you were pulling feb and nov 2013 data

Answer 24

okay, so from here on out I can use plotyy ?

Answer 25

yes

Answer 26

you'll have [1:1:120] as the x vector to represent day 1 through 120 (nov 1st through feb 28th)

the y values will differ for the 2 data sets

see the figure at the top of page 4

Answer 27

thinking

Answer 28

so my y values are winter13_14_sf and winter12_14_sd ?

Answer 29

correct

Answer 30

plotyy([1:1:120], winter13_14_sd, [1:1:120], winter13_14_sf);

Answer 31

yeah that should work

Answer 32

so i suppressed the previous plots. When I run the code it displays four subplots, the 4th one displaying two graphs in one box.

Answer 33

that's not supposed to happen

hmm

Answer 34

you need to create an entire new figure for the new plot

Answer 35

plotyy([1:1:120], winter13_14_sd, [1:1:120], winter13_14_sf);

so it looks like it works when I suppress the previous subplots

Answer 36

let me attach an image

Answer 37

I'm not sure how to make a new figure, so I guess the best way to do it is to break it up into different cells. Cell 1 has figure 1, cell 2 with figure 2, etc etc

Answer 38

okay

Answer 39

but the graph you posted looks good
