chaco - Python: takes exactly 1 argument (0 given) Error -


i created method called create_plot pass x, y1, x_axis_name, y_axis_name values create python chaco graph. 

    def create_plot(self, x, y1, x_axis_name, y_axis_name):           self.x = x           self.y1 = y1           self.x_axis_name = x_axis_name           self.y_axis_name = y_axis_name           plotdata = arrayplotdata(x, y1)           plot = plot(plotdata)           plot.x_axis.title = x_axis_name #string example "(s)"           plot.y_axis.title = y_axis_name #string example "(m)"            renderer = plot.plot(("x", "y1"), type="line", color="blue",            width=2.0)[0]            renderer.overlays.append(lineinspector(renderer,            axis='value',write_metadata=true, is_listener=true))            plot.overlays.append(zoomtool(plot, tool_mode="range"))           plot.tools.append(pantool(plot))           container = hplotcontainer(background="lightgray")           container.add(plot)           return container       def _create_plot_component(self):            self.wind_speed_graph = self.create_plot(time_list,             data_list, "(s)", "(m)")       wind_speed_graph = instance(component)     def _wind_speed_graph_default(self):            return _create_plot_component()

when compile error "_create_plot_component() takes 1 argument (0 given)". "create_plot" right method created? how can fix error?

you need call method class instance (non-static) class method.

solution similar this. can't tell certain, because fair amount of code seems missing.

def _wind_speed_graph_default(self):     # note my_instance     return my_instance._create_plot_component()

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
