import uikit import coredata  let appdelegate: appdelegate = uiapplication.sharedapplication().delegate as! appdelegate let context: nsmanagedobjectcontext = appdelegate.managedobjectcontext class garageviewcontroller: uiviewcontroller, uicollectionviewdelegate,uicollectionviewdatasource {  @iboutlet weak var backgroundview: uiimageview!  @iboutlet weak var collectionview: uicollectionview!  var voitures: [voiture]  = [voiture]()  override func viewdidload() {     super.viewdidload()      collectionview.reloaddata()      let fetchrequest = nsfetchrequest(entityname: "voiture")     fetchrequest.resulttype = .dictionaryresulttype      {         try voitures = context.executefetchrequest(fetchrequest) as! [voiture]     }     catch let fetcherror nserror {         print("voiturefetch error: \(fetcherror.localizeddescription)")     }      if (voitures.count > 0) {         voiture in voitures [voiture] {              print(voiture.nom!)          }     }     else {         print("aucune voiture")     }  }

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...
