I have installed SPM version 12, and subsequently, I installed spm1d version M.0.4.10 (dated September 23, 2022). I used the following code to perform a paired t-test:
spm = spm1d.stats.ttest_paired(Ext_D, Ext_F);
spmi = spm.inference(0.05, 'two_tailed', true);
spm.plot();
The spmi object is successfully created, but when I attempt to plot it in MATLAB, I encounter a warning: 'Unrecognized method, property, or field 'plot' for class 'spm1d.stats.spm.SPM0D'.'
I'm seeking assistance to resolve this issue. Can someone please help me?

Sorry, I posted this in the comments section by mistake.
spm1d.plot.plot_meanSD(YA,'color','r');
hold on;
spm1d.plot.plot_meanSD(YB,'color','b');
title('Data','FontSize',18);
legend({'YA','YA SD','YB','YB SD'});
%(1) Conduct SPM analysis:
spm = spm1d.stats.ttest2(YA, YB);
spmi = spm.inference(0.05, 'two_tailed',true, 'interp',true);
% disp(spmi);
%(2) Plot:
subplot(1,2,2);
spmi.plot();
spmi.plot_threshold_label();
spmi.plot_p_values();
title('SPM analysis','FontSize',18);

Hi!
Seeing your data, you data size is [250,1].
Does the row represent time point?
If you want to do SPM1d, the size of the data should be [subject, timepoint].
