Final answer:
The statement is true. The 'hold on' command is used in platforms like MATLAB to prevent a figure from being overwritten by subsequent plot commands, thus allowing multiple datasets to be visualized together.
Step-by-step explanation:
True, the command hold on in programming environments, such as MATLAB, is used to allow multiple plots to be drawn on the same figure without overwriting previous plots.
This is particularly useful when you want to compare graphs or display multiple datasets together.
After you are done plotting all the desired data, you should use hold off to allow new plots to overwrite the figure as usual.
