I showed a client a draft of a Viz where I had the colour set as Diverging based on if they where over or above target. I also included the Key showing the Diverging colour. They loved the Key and decided that is what they want! Essentially they just want one Bar from 0-100 with a colour fading red to green and a mark on it based on their current position.
Is this possible as I have struggled to create it! I have included a print screen of what it is they are after. The Key showing the colour is exactly what they want but as a chart with mark for current position?
