Printing hexadecimal characters in C
...
You are probably printing from a signed char array. Either print from an unsigned char array or mask the value with 0xff: e.g. ar[i] & 0xFF. The c0 values are being sign extended because the high (sign) bit is set.

Matplotlib scatter plot with different text at each data point

I'm not aware of any plotting method which takes arrays or lists but you could use annotate() while iterating over the values in n.
y = [2.56422, 3.77284, 3.52623, 3.51468, 3.02199]
z = [0.15, 0.3, 0.45, 0.6, 0.75]

...ng-point additions, but to cope with really bad cases you can keep a whole array of running totals at different magnitudes, add each new value to the total that best matches its magnitude, and when a running total starts to get too big for its magnitude, add it into the next total up and start a new...
