(You will be asked for a Company name and an email address. We will only use this to contact you about MeterGrapher updates.)
N.B. Re-installing will overwrite AnswerGrapher.xlsm and MGUsageCalcs.xlsm - please save these with new names if you have data in them.
Please look at the User Docs. MeterGrapher is feature-rich and you will get the best out of it if you know what it can do!
