how to assign value to a point in a hexagonal coordinator system

Hi, I got xv,yv which are the vector positions of the points. I want to assign the value I_hex to these corresponding positions and then use "Surface and Mesh Plots commands" to plot the magnitude of each points. Please help Thanks

xv =[0   -0.5    0.5    1    0.5   -0.5 -1];
yv =[0   -0.8660   -0.866   0    0.866    0.866    0];
I_hex =[0.1508 + 5.2524i   0.1975 + 2.6562i   0.1975 + 2.6562i   0.1975 + 2.6562i   0.1975 + 2.6562i   0.1975 + 2.6562i    0.1975 + 2.6562i];
