Multiple Plots on Single Figures in Loop

Hello - I currently have large datasets that makes loading them all first inpractical. So I created a large loop that will go through and plot everything I need from the first dataset, then delete that from memory, and load the next data set. It will put the plots on the same Figure (#) as the prior data set so I get a series of Figures with many plots across multiple sets of data.

However, I'm trying to add titles to the figures (not above the actual plot, but so that plot browser show's a description instead of Figure 1, 2, etc. , but now it creates a new figure each time through the loop with another data set.

plotbrowser('on') %turn plot browser on
figure (1) %Plot vehicle speed trace
figure('Name', 'Vehicle Speed','NumberTitle','off');   <--- If I comment this out it functions correctly, but the figures are missing titles I desire.
title('Vehicle Speed Trace');
hold on

'It will put the plots on the same Figure (#) as the prior data set so I get a series of Figures with many plots across multiple sets of data.'

are you plotting on the same axes, creating new axes on the same figure, or are you creating a new figure along with a new figures.

Mulitple sets of data on the same plot with the same axis.

figure()

will automatically create a new figure.

figure (1) %Plot vehicle speed trace
figure('Name', 'Vehicle Speed','NumberTitle','off');   <--- If I comment this out it functions correctly, but the figures are missing titles I desire.

^ you are creating two figures here.

What I would do is assign handles to the figures, and I can always refer back to them elsewhere in my code. Assigning handles/tags to your axes can help in referring to them too.

for example:

f= figure
set(f,'Name','VehicleSpeed','NumberTitle','off')

let me know if this helps.

Sorry I'm not super experienced here... I tried your solution (I think?).

Outside the loop I put your code:

f= figure
set(f,'Name','VehicleSpeed','NumberTitle','off')

Inside the loop I just called the figure

figure(f)

However I'm still getting a figure each time through the loop. What I don't understand is why when I just call it a generic number Figure (1), it creates a single Figure (1), and each time through the loop it adds the new plot with the other plots. But that doesn't seem to work when I called it Figure(xyz).

[Kevin Phung]

that's strange. Can I see how you're plotting? If you just the data on one figure, you dont need to call it again in the loop. Although I dont think this should have mattered.

Also, you can access properties of a figure by just calling out its handle.

Can you verify with me that the 'NextPlot' property of the figure is 'add'

f.NextPlot

[MustangManiac]

plotbrowser('on') %turn plot browser on
figure (1) %Plot vehicle speed trace
% figure('Name', 'Vehicle Speed','NumberTitle','off'); 
title('Vehicle Speed Trace');
hold on

VehSpeed_Interp = interp1(Data.test_data(index).data.time, Data.test_data(index).data2.vspd_corrected, TimeIndex); 
a1 = plot(TimeIndex,VehSpeed_Interp); %Plot
legend (a1,l1);
legend('

This is what each figure in the loop is basically like.

');

what confuses me is your goal: you want to plot data sets in a loop but have them erased before each new iteration.. your end result is just going to be a plot of whatever your last data set is.

Can you try to not call out the figure in the loop?
