cool! now it become neater 
i am run into another issue here, instead of two state my ‘z’ value now include another state (0, 1, 2) and i wish to use discrete color scale with green for 1 and dark green for 2 but it turns out giving me red and orange.
colorscale=[[0, ‘rgb(238, 238, 238)’], [1, ‘rgb(48, 137, 29)’], [2, ‘rgb(118, 207, 99)’]]
