Muddy y axis and plotting using coordinates

Hi everyone,
I am a newbee of Matlab. I am having some issues with plotting. I could use some help.
When I try to plot multiple sets of data, the axies get mudy. I assue it's caused by the overlapping of different scales. Is there a way to clean it up?
T1=[50 53 55 58 59 60 61 61 62]
T2=[ 48 50 52 54 55 57 58 59 60 61 62 62 63]
dCoF1=[2.088360144 2.348487525 2.48784046 2.67016458 2.795948305 2.84171836 2.619815575 2.663693217 2.6249562]
dCoF2=[3.370696371 2.075218238 2.272783201 2.440811388 2.444426417 2.614530643 2.585023679 2.531044092 2.666287724 2.59727857 2.603275966 3.366966847 2.685168655]
p=plot (T1,dCoF1,"-k",T2,dCoF2,"-c")
p(1).Marker="*"
p(2).Marker="o"
Another issue is that I have a set of data that describe force reading under different temperatures. Naturally I want to visualize the data points. Making the data coordinates fall into "temperature bins". Currently I am using line plot, but I am sure there is a better way to do it.
My Data set:
[(Temperature, Reading)] = [(55,1.98);(58,1.88);(61,2.00);(55,1.93);(56,1.74);(56,1.88)]
I am thinking asking Matlab to plot based on coordinates, but I don't know how to use a matrix to store the coordinates, and use the plot function.Can you give me any insight?

I get a much ‘cleaner’ result that what you posted.
What MATLAB release are you using?
Have you updated it with the latest Update?

Hi Star Strider,
I am using '9.9.0.1592791 (R2020b) Update 5'.
This issue happened after I plot some data using "hold on".
Actually today I ran this section and the issue is gone. Maybe I should share this piece:
ax = axes;
ax.ColorOrder = [1 1 0;1 0 1; 0 1 1; 1 0 0; 0 1 0; 0 0 1; 1 1 1; 0 0 0]
hold on
for i = 1:22
plot([1:48285],result(:,i))
end
hold off
Please let me know.

If they all have the same length (with respect to the independent variable, as they appear to do in this Comment), try something like this:
x = 1:20;
y = rand(5,20)+(0:4).';
figure
plot(x, y)
ax = gca;
ax.ColorOrder = [1 1 0;1 0 1; 0 1 1; 1 0 0; 0 1 0; 0 0 1; 1 1 1; 0 0 0];
