Libre office Calc 5.0.5.2.
Ubuntu 15.10.
Created spread sheet by opening text file and then graphing the data. But every option for saving the file results in an error message: “Error saving the document result:
Wrong parameter.
The operation was started under an invalid parameter.”
I found the following link which could be useful…How can I save a spreadsheet with a chart on it?
Make certain that you have NOT selected the chart before saving the file…Peter
