overlap ylabel with values axis

i have this problem both for x axis anz y axis, how can i solve?

another question: how can i convert input data to character? Sometimes i use the option x='1.2e7' but i would to generalize and use it both for legend and write a new file. I have tried to use num2str but the number 1.2e7 becomes 12000000

Answer 1

[Walter Roberson]

format long g
x = 1.2e7

x = 
    12000000

num2str(x, '%.1e')

ans = '1.2e+07'

sprintf('%.1e', x)

ans = '1.2e+07'

compose('%.1e', x)

ans = 1×1 cell array
    {'1.2e+07'}

num2str() invokes sprintf() internally (except for integers, if I recall -- I think it calls int2str() for those.)

compose() can be useful for outputing arrays; sprintf() is a nuisance for outputing arrays of different types.

However... if you need to be able to distinguish between x = 12.e6 and x=1.2e7 and automatically output exactly the same way that it was input, then you are going to need to input as character (or string) and str2double() when you need the numeric form.

If you ask to retrieve the YLabel property of the axes, then you will get back a text() object. text() objects have a Position property, which you can change to move the place the text is placed.

[AndresVar]

many ways to modify the label position: modify position property, if in latex add \quad, etc

the easy way is to control the horizontal alignment

a = (1:3)/10

a = 1×3

0.1000 0.2000 0.3000

figure;
plot(a);
yl=ylabel('aaaaaaaaaaaa','Rotation',0);

figure;
plot(a);
yl=ylabel('aaaaaaaaaaaa','Rotation',0,'HorizontalAlignment','right');
