Graph tiltle with multiple variables over 2 lines

I Have been tryint to make the variables contained in this title append over two maybe three lines, following the use of {} brackets. But so far it returns 3 per lines per num2str. Could anyone help point appropriate corrections to obtain 2 maybe three lines.

thanks

title({'Request dur= ' num2str(timeseriesMatPurgeRequest{II}{X}.time(end)),'s,  Request Dist = ' num2str(timeseriesMatPurgeRequestvalues(1)),'km', 'NOx eff = ' num2str(((timeseriesMatPurgeRequestvalues(1)-timeseriesMatPurgeRequest{II}{X}.ExM_mStrNOx_ExEle.signals.values(end))/timeseriesMat.values(1))*100) '%, Dilution = ' num2str(((timeseriesMatPurgeRequest.values(1)-timeseriesMatPurgeRequest{II}{X}.elomm_w_fio_out_01.signals.values(end))/timeseriesMatPurge.values(1))*100) '%','AcvRul = ' num2str(timeseriesMatPurgeRequest.values(1)) ', Total Rich Time = ' num2str(sum(mode(diff(timeseries.time))*numel(find(timeseriesMat.values<1)))) 's', 'NOx Remove Rate = ' num2str(((timeseriesMatvalues(1)-timeseriesMat.values(end))/(sum(mode(diff(timeseriesMatPurge.time))*numel(find(timeseriesMat.values<1))))))'})

Franc - try using sprintf to create one or more lines that you can use in your title. For example,

myTitle = sprintf('first row has integer: %d\nsecond row has float: %f\n', 42, pi);
title(myTitle);

Note how you do not have to convert any of your numbers into strings (the '\n' is used to indicate a new line). You may want to use local variables for the calculated values rather than trying to do them all on one line of code. i.e.

totalRichTime = sum(mode(diff(timeseries.time))*numel(find(timeseriesMat.values<1)));
duration = timeseriesMatPurgeRequest{II}{X}.time(end);
myTitle = sprintf('duration = %fs\ntotal rich time = %fs', duration, totalRichTime);

or something similar.

Great thanks, ill give it a try and respond

This solution has not worked out, it results is a repeat of a single variable across the plot

[Geoff Hayes]

please show your code and/or describe what you mean by a repeat of a single variable across the plot...

Hi

my code is as below, ultimately i'm looking to have max3 variables per line but the resultant variable of the just the one in the sprintf repeats 3 times on the graph and other line do not show. so maybe i have the syntax wrong.

Requestdur=  num2str(timeseriesMatPurgeRequest{II}{X}.ATSys_noATSysRgnReq.time(end));'s';  
                        RequestDist =  num2str(timeseriesMatPurgeRequest{II}{X}.OdometerMasterValue.signals.values(1)); 'km';
                         NOxeff =  num2str(((timeseriesMatPurgeRequest{II}{X}.ExM_mStrNOx_ExEle.signals.values(1)-timeseriesMatPurgeRequest{II}{X}.ExM_mStrNOx_ExEle.signals.values(end))/timeseriesMatPurgeRequest{II}{X}.ExM_mStrNOx_ExEle.signals.values(1))*100); '%'; 
                        Dilution =  num2str(((timeseriesMatPurgeRequest{II}{X}.elomm_w_fio_out_01.signals.values(1)-timeseriesMatPurgeRequest{II}{X}.elomm_w_fio_out_01.signals.values(end))/timeseriesMatPurgeRequest{II}{X}.elomm_w_fio_out_01.signals.values(1))*100); '%';
                         AcvRul =  num2str(timeseriesMatPurgeRequest{II}{X}.ATSys_noRgnAcvRul.signals.values(1));  
                         TotalRichTime =  num2str(sum(mode(diff(timeseriesMatPurgeRequest{II}{X}.LSU_rLam__0_.time))*numel(find(timeseriesMatPurgeRequest{II}{X}.LSU_rLam__0_.signals.values<1)))); 's';
                         NOxRemoveRate =  num2str((timeseriesMatPurgeRequest{II}{X}.ExM_mStrNOx_ExEle.signals.values(1)-timeseriesMatPurgeRequest{II}{X}.ExM_mStrNOx_ExEle.signals.values(end))/(sum(mode(diff(timeseriesMatPurgeRequest{II}{X}.LSU_rLam__0_.time))*numel(find(timeseriesMatPurgeRequest{II}{X}.LSU_rLam__0_.signals.values<1)))));'g/s';    
                         myTitle = sprintf('Requestdur = %fs' ,Requestdur);
                         title(myTitle);

Hi Franc - since we are using sprintf and %f, this means that we don't have to conver the Requestdur to a string. So we can simply do

Requestdur = timeseriesMatPurgeRequest{II}{X}.ATSys_noATSysRgnReq.time(end);  
myTitle = sprintf('Requestdur = %fs' ,Requestdur);
title(myTitle);

If it still prints three lines, then this could be because of the data. Is Requestdur a scalar or is it an array?

As for the other lines do not show, I don't know what you mean by this. Do you mean the other variables don't show? If that is the case, then that makes sense since you are only writing/including Requestdur in your title...and not the others.

[Franc]

Hi Geoff, added a screen shot of the result of the one line sprintf.

so you can see what the issue is, this is subplot of variable quantity and each one would have the same format output.

[Geoff Hayes]

Hi Franc - so it looks like your Requestdur is an array. Is that what you are expecting?

[Walter Roberson]

With the (end) indexing at the end of timeseriesMatPurgeRequest etc., then Requestdur would have to be a scalar. If II was non-scalar or X is non scalar or ATSys_noATSysRgnReq is a non-scalar structure, then you would have received a runtime error about attempting to index improperly. The only way you could get Requestdur as a vector there without significant changes to the code is if you omitted the (end) indexing.

[Franc]

Geoff/Walter, I was reading the documentation a bit more i realised I could use [ ] within the { } to partition the code and then using ; between the [ ] to add another line.

So really appreciate your helping me think through it. Sample added.
