Chart in Sub Vi is empty

Question

Hi,
I created a Sub VI that creates a chart, formats it and exports the chart to JPG format. Now when I call the Sub Vi this doesn't work. I am only getting an empty chart displayed in the JPG format. It only works if I have the Sub Vi open at the same time I am running the main program. This is not a permanent solution since I need to compile the program as stand alone.
Anyone an idea or work around?
I somehow this it muse be some of refresh method of the pane or chart object.
I am using LV 8.2.1

You can set it to show the FP when called, but make the FP 100% transparent.
Some comments:
You don't need to write all these font, etc. properties. They are saved with the VI and only need to be set when things change.
Initiaizing to default will clear the history also, so you don't need to do that twice.
Overall, your code is way too chopped up with local variables and sequences.
Since everything is quite linear and execution order is defined by the error cluster, all you need is a flat diagram (see attached draft).
You should avoid manipulating paths as strings, it breaks OS independence. Your cluster should have a path constant instead of a string.
