To get better direct printing from LV, make a Print VI instead ofusing
the GetImage functions.
Copy the graph to a new VI and customize it however you would like for
the printout, typically you will make parts transparen
t or hide them,
perhaps move the legend. Set the VI to print at completion, and in your
program when you have data you want printed on the graph, call the subVI
passing the data to the graph. Note you will likely want to have a
string indicator or some numerics next to the graph to give information
about how the data was acquired or other useful information.
This VI will print at high resolution adapting to the printer it is
going to, unlike a jpg or any other image.
