How to change x and y labels limts

Hi,

I have a problem with my plot axes labels. I want to have my own range on x-axis and y-axis. On the y - 0:200 and the interval 20. On the x (time mm:ss) - 00:00 : 20:00 and the interval 2 minutes.

a=['00:00';
'00:42';
'00:49';
'00:56';
'02:00';
'02:24';
'02:52';
'03:23';
'04:22';
'05:52';
'06:41';
'08:40';
'09:18';
'10:27';
'11:01';
'11:14';
'11:31';
'11:49';
'12:04']
b=[27.6;
32.1;
37.9;
41.1;
68;
79.6;
89.7;
92.5;
93.4;
93.4;
93.7;
100.3;
109.8;
135.8;
151.1;
160.4;
167.5;
174.6;
179.7]

c=datenum(a, 'MM:SS'); 
plot(c,b,"-o");
xlabel("Czas [min:sec]")
ylabel("Temperatura [%%cC]")
hold on;
datetick('x','MM:SS')

Use duration instead of deprecated datenum/datetick and set the xtick values as desired.

You likely won't have sufficient room to show that many tick marks with time as the axis label.

Can you help me with the code? I don't know how to use duration.

[dpb]

How did you learn to use datenum? Read the doc first and give it a go...much faster than waiting on us.

Anyone else can help me with my problem?

[Ameer Hamza]

dpb told you a method. Have your tried that?

[Damian Konaszewski]

Yes. When I put duration i got error. When I use xtick, the label didnt; fit to reality.

"When I put duration i got error. When I use xtick, the label didnt; fit to reality. "

Must not have tried very hard or read the doc at all... :(

d=duration(cellstr(a),'InputFormat','hh:mm','Format','hh:mm');
plot(d,b)
xlim([hours(0) hours(14)])
ylim([0 200])
xticks(hours(0:2:14))
grid on

produces:
