I am using Colormix for a chart with a date/hh as dimension. I want the chart to go lighter and darker depending on HOUR in the day. So if the user is looking at 2 days, the bars between 6 am and 6 pm would be brigther and get darker going to midnight.
However I want the gradient shading to go in both directions. Getting brighter from about 5 am till about noon, then gradually darker from noon through the evening.
Using Colormix I have it gradient in one direction only and I have to pick the morning hour to start. I want it gradient in both direction with the midpoint being noon.
