make a png and each section should be divided into 24 regions 12 x 2 the top 12 are unpluged the bottom are plugged in. Left to Right being dead to full.
Just go to the batery meter in plazmic and where it says "Batter Meter," click it and hit edit. Make sure under preferences the application is set to GIMP or Photoshop or whatever you are using. Then you can just edit the colors, etc.
okay so do the dimensions have to be divisible by 12 x 2? what if it's a vertical-shaped meter instead of horizontal?
doesnt matter what shape as long as the width is divisable by 12 and the height by 2. the signal indicator is a little different its just one row and i forget how many sections.
