I want to see the text & strings in a single line of Xlabel

Hi,

I wish to see the text and string in a single line as

"Timeseries 2019-09-04T14:53:20 to 2019-09-04T15:10:00".

But I get the xlabel as 4 lines (4 different array) as

"Timeseries

2019-09-04T14:53:20

to

2019-09-04T15:10:00"

xlabel(['Timeseries' string(timestamp(end-1)) 'to' string(timestamp(end))]);

Can anybody pull me out from here? Thanks in advance

Try this:

timeseries = ['2019-09-04T14:53:20';'2019-09-04T15:10:00'];                     % Create Array
xlabel(sprintf("Timeseries %s to %s", string(timeseries(end-1:end,:))))

.

this doesn't work here. The following message comes

Error: "Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses."

My test code ran without error when I tested it. I do not have your ‘timestamp’ array so I cannot test my code with it.

My approach uses the sprintf function rather than concatenating strings to produce the xlabel string. That is generally a better approach.

I just finished the comment thanking you @VBBV

"The interesting thing is that 'Star Strider' he used the array which also works! So, both answers are correct."

Now, I'm confused which answer need to be accepted?

Thanks both of you.

For my part, my pleasure!

Answer 2

%if true
  xlabel(['Timeseries' num2str(timestamp(end-1)) 'to' num2str(timestamp(end))]);

Use num2str

[SA]

Thanks but 'num2str' doesn't work in this case. error message like

"Error using num2str (line 53)

Input to num2str must be numeric."

N.B.: timestamp is 2019-09-04T14:53:20 format

[VBBV]

%if true
 timeseries = {'2019-09-04T14:53:20';'2019-09-04T15:10:00'}; 
xlabel(['Timeseries', timeseries{1}, 'to',timeseries{2}])

This should work

[SA]

your piece of code is wright but can't work for me. my timeseries look like

timeseries =datetime(TimeStamp,'ConvertFrom', 'yyyymmdd', ...
                     'TimeZone', 'UTC', ...
                     'Format', 'uuuu-MM-dd''T''HH:mm:ss');

error: "Cell contents reference from a non-cell array."- as my case timeseries is an array of size=N-by-1

[VBBV]

In that case convert timeseries to cell array as shown below and access the first and last values as below

%if tru
T = cellstr(timeseries);
xlabel(['Timeseries', T{1}, 'to',T{end}])

[SA]

This time it works! The interesting thing is that 'Star Strider' he used the array which also works! So, both answers are correct. Now, I'm confused which answer need to be accepted?

Thanks both of you.
