I want values from a comma separated file to plot data on my TChart. Heres my problem. I tried doint a StrToFloat, all the data from the file is in the form 3434.3434. My input locale is danish where we use comma instead. I tried both doing ti with 334.3434, and with 3424,24545 and always get an error about it "not being a floating point value". Another issue with this, is the program has to run on machines with different input locales. How to i make this independent, the file it has to read is always in the same format.

Hi Loke, Setting DecimalSeparator (either dot or comma) before populating series, like the code below, works fine here: DecimalSeparator:=','; Series1.Add(StrToFloat('32145,32155')); Series1.Add(StrToFloat('33145,32155')); Series1.Add(StrToFloat('34145,32155')); Series1.Add(StrToFloat('35145,32155')); -- Best Regards, Narcís Calvet http://support.steema.com "Important note: If you are a TeeChart registered customer, please post your support questions at Steema's Support monitored Forums for customers: http://support.steema.com for a prompter reply."
