I would like to have a text box in the interface that the user inputs a "sample ID" into. I have my setup logging the data to a file. So when this file is created I would like to retrieve the text from the text box and then log it to the file, as the first line.

Basically something like this ...

Phil,

Yes, changing line 120 in the library to be as shown below solves the problem and gives the same number of decimal places for both X and Y values.

m_rDestination.print(*xValues++, nDecimalPlaces);

Thanks,
Jeff

I am plotting data on an XYplot.

Here is the Arduino code that is sending the data. Note the 4 for nDecimalPlaces
void updateUserInterface() {
plotArticulation.SendData("Articulation", wirePullDistance, articulationAngle, 4 );
plotArticulation.SendData("Force", wirePullDistance, force, 4 ...
