Bubble chart coloring

Migrateduser

<p><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">Hi again, Here is another kind of question about charts : bubble chart. I am building a bubble chart and I wish to assign a color according to a value of my dataset which is not in the chart. I suppose that I have to use code in order to realize it (Cf. attachment : screenshot) On the screenshot the result that I wish : assign a special color to the area. Any idea to implement this for HTML5 Charts in iHub3? Thank you.</span></p>
