Heatbar, dynamic position offset of text

[dunham]

I want to insert a new column in my report to graphically display a "needle" displaying the position in a range of 0% - 100% like so:

I am looking for ideas please!

My idea

• Use graphic (rainbow 0%-100% in every detail column).
• Use a pixel offset (somehow??) where I simply place an overly large "|" type. So if 0%-100% are 200px that would mean that to display the needle at 50% I would offset the type 100px!
