html - javascript function to color using color array and for loop -

-

i have created function create html elements json object. have created array of 3 different colors , want loop through array, using each color @ time color part of sentence formed html elements. there 2 roles in particular object (ie. singlejsonobj.roles.length equal 2). trying print first html element "darksalmon" , next 1 "forestgreen" loops. is, however, printing both role names "darksalmon". please see code below. missing?

function createhtmlelementsforrolenumbers (singlejsonobj, xml) {  // result returned     var finalxml;      var colorarr = ["darksalmon", "forestgreen", "brown"]  // block of html elements created     var htmlforrolenumbers = "";      ( var i=0; i< singlejsonobj.roles.length; i++)     {         // each time creating 1 html element.         // e.g. if length above 2, create 2 h4 elements.         htmlforrolenumbers = htmlforrolenumbers +             "<h4><br> - a(n) <font color='" + colorarr[i] + "'>" +                 singlejsonobj.roles[i].name +             "</font><br></h4>";      }     finalxml =  string(xml).replace(/role_numbers/g,htmlforrolenumbers)      // output     return finalxml; }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
