评论： Steen 2023-1-31

I am using the below code to import data from text file. The code is working, but the .Fig file are very slow afterwards

Is the code ok, or is there a better way

datafile = 'Test_1_pre_test_with_Prose_Fan_Load_streng_1_error_at_8_procent_115222_230119_TEST_1.txt';
T = readtable(datafile,'Format','auto');
T1 =T;
hold on
t = T1.TIME;
P = T1.Properties.VariableNames(2:end);
for K = 1 : length(P)
    fn = P{K};
    plot(t, T1.(fn), 'DisplayName', fn);
end
hold off
set(gcf, 'visible', 'on')
legend show

I might be because of file size. If I make a shorter file, I can save it. But I cant change the file size og why can do you think I can save the file, when using the below code

datafile = 'Test_1_pre_test_with_Prose_Fan_Load_streng_1_error_at_8_procent_115222_230119_TEST_1.txt';
T = readtable(datafile,'Format','auto');
T1 =T;
hold on
t = T1.TIME;
P = T1.Properties.VariableNames(2:end);
for K = 1 : length(P)
    fn = P{K};
    plot(t, T1.(fn), 'DisplayName', fn);
end
hold off
set(gcf, 'visible', 'on')
legend show
