I would like to plot a bar chart with a color gradient as its value change color must be change. How can I do that.

For example

data = [1.4 2.1 3.3 4.5 5.4];

c = [0.3 0.4 0.5 0.6 0.7];

I would like to have a single bar plot from 1.4 to 5.4, and each point on that bar chart has their own color based on the value in c array.

How can I do that ?

What I mean is forming graph from this equation

Z = (0.51019.*X)-Y;

gradient color is Z value.

x range of bar graph is the X value.

And each bar represent constant Y value in that equation.
