var buffer = require('buffer').buffer;  function stringtobytes(str) {      var bytes = [];      (var = 0; < str.length; ++i) {          bytes.push("0x"+bytetohex(str.charcodeat(i)));     }      return bytes; }  function bytetohex(b) {     var hexchar = ["0", "1", "2", "3", "4", "5", "6", "7","8", "9", "a", "b", "c", "d", "e", "f"];     return hexchar[(b >> 4) & 0x0f] + hexchar[b & 0x0f]; }   parse.cloud.define("exportdata", function (request, response) {     var jsonstring =[{"vehicle":"bmw","date":"30, jul 2013 09:24 am","location":"hauz khas, enclave, new delhi, delhi, india","speed":42},{"vehicle":"honda cbr","date":"30, jul 2013 12:00 am","location":"military road,  west bengal 734013,  india","speed":0},{"vehicle":"supra","date":"30, jul 2013 07:53 am","location":"sec-45, st. angel's school, gurgaon, haryana, india","speed":58},{"vehicle":"land cruiser","date":"30, jul 2013 09:35 am","location":"dlf phase i, marble market, gurgaon, haryana, india","speed":83},{"vehicle":"suzuki swift","date":"30, jul 2013 12:02 am","location":"behind central bank ro, ram krishna rd by-lane, siliguri, west bengal, india","speed":0},{"vehicle":"honda civic","date":"30, jul 2013 12:00 am","location":"behind central bank ro, ram krishna rd by-lane, siliguri, west bengal, india","speed":0},{"vehicle":"honda accord","date":"30, jul 2013 11:05 am","location":"dlf phase iv, super mart 1, gurgaon, haryana, india","speed":71}];     var csvstring = jsontocsvconvertor(jsonstring, "export", true);     var dataforfile = new buffer(csvstring).tostring('base64');     var dataforfile2 = stringtobytes(csvstring);     var parsefile = new parse.file("userid4_car.csv", dataforfile2);     parsefile.save().then(function() {         response.success(parsefile);     }, function(error) {         response.error(error);     });  });

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...
