[bunghole]

hi, i need to know if there is anyway to link bar graphs together to form a led analogue meter for a speedometer. Is it possible to use a LM3914M?

hi,
I use www.datasheetarchive.com

Type in the part number in the search box then click on 'pdf' to download.

Google for 'charlieplexing' it is good for twenty LED's and draws far less current, and you have a much better choice of display style. Microchip had this in their Tips-n-Tricks about 3 years ago.
