android - GAE Reading from Datastore -

-

i want return myhighscores datastore: i.e.: paul,1200 tom,1000 kevin,800

private void returnhighscores(httpservletresponse resp, string game, int max) throws ioexception {     datastoreservice datastore = datastoreservicefactory.getdatastoreservice();     key gamekey = keyfactory.createkey("game", game);     query query = new query("highscore", gamekey);     query.addsort("points", query.sortdirection.descending);     list<entity> highscores = datastore.prepare(query).aslist(fetchoptions.builder.withlimit(max));      for(entity e : highscores) {         resp.getwriter().println(e.getproperty("name") + "," + e.getproperty("points"));     } }

and working :) ! when want read returned highscores , add string textview with:

androidhttpclient client = androidhttpclient.newinstance("mueckenfang");         httppost request = new httppost(highscore_server_base_url + "?game=" + highscoreserver_game_id);          httpresponse response = client.execute(request);         httpentity entity = response.getentity();         inputstreamreader reader = new inputstreamreader(entity.getcontent(), "utf-8");         int c = reader.read();         while (c > 0) {              highscores += (char) c;             c = reader.read();         }         textview tv = (textview) findviewbyid(r.id.highscoretv);         tv.settext(highscores);

i html code like:

><html><head><meta http-euiv="content-type"content="text/html;charset=utf-8"><title>405 gttp method post is....

but want paul,1200 tom,1000 kevin 800 , on

httppost not accepted query parameter, "?game=" + highscoreserver_game_id.

you need pass values 

androidhttpclient client = androidhttpclient.newinstance("mueckenfang"); httppost request = new httppost(highscore_server_base_url); list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(1);   namevaluepairs.add(new basicnamevaluepair("game", string.valueof(highscoreserver_game_id)));     request.setentity(new urlencodedformentity(namevaluepairs));  httpresponse response = client.execute(request); httpentity entity = response.getentity();

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...
