I have a plot with two lines. This plot was generated using a GUI that runs on MatLab. I want to change the width of the two lines using code rather than the plot editor. I used findobj to get the line handles but I can't get the code to work to change the width. I assume DataLine is the handle for both lines. I've tried variations of the last two lines below.

h2 = findobj('Type', 'line');
h2 = 
5×1 Line array:
Line    (TimeZeroLine)
Line    (Cursor)
Line
Line    (DataLine)
Line    (DataLine)
line(DataLine,'LineWidth',10);
set(DataLine,'LineWidth',10);

在 MATLAB Online 中打开

h2 = findobj('Type', 'line')
% h2 = 
% 5×1 Line array:
% Line    (TimeZeroLine)
% Line    (Cursor)
% Line
% Line    (DataLine)
% Line    (DataLine)
% use index in h2 to refer to the lines you want to modify
set(h2([4 5]),'LineWidth',10)
