not necessarily. gwt java does introduce some overhead, but the gwt compiler generates optimized javascript from the java code, and just leaves native code as you wrote it. so all things being equal, java code is probably often faster than native code, especially long native methods like the one you sent. > and > want to try if it works? but now i switch back to java wrapper as i > can't solve the native method issue. > > On Jul 9, 1:25 pm, MC Get Vizzy <[email protected]> wrote: > > is there a reason you're using the AjaxLoader directly instead of the > > VisualizationUtils? > > thanks, > > > > MC Get Vizzy > > > > P.S. is there a reason that you're doing so much stuff in a native > method > > instead of in java? > > > > On Thu, Jul 9, 2009 at 12:47 PM, imgnik <[email protected]> wrote: > > > > > hi all, > > > > > i tried but the motion chart doesn't seems to appear when load with > > > ajaxloader. please advise me. below is my code: > > > > > public void onModuleLoad() { > > > > > > verticalPanel.getElement().getStyle().setPropertyPx("margin", > > > 10); > > > verticalPanel.setSpacing(10); > > > RootPanel.get().add(verticalPanel); > > > > > AjaxLoaderOptions options = AjaxLoaderOptions.newInstance(); > > > options.setPackages("motionchart"); > > > > > AjaxLoader.loadApi("visualization", "1", new Runnable() { > > > > > public void run() { > > > motionChartLoaded(); > > > } > > > }, options); > > > } > > > > > private native void nativeMakeMotionChart(Element chartDiv) > /*-{ > > > var data = new $wnd.google.visualization.DataTable(); > > > data.addRows(6); > > > data.addColumn('string', 'Fruit'); > > > data.addColumn('date', 'Date'); > > > data.addColumn('number', 'Sales'); > > > data.addColumn('number', 'Expenses'); > > > data.addColumn('string', 'Location'); > > > data.setValue(0, 0, 'Apples'); > > > data.setValue(0, 1, new Date (1988,0,1)); > > > data.setValue(0, 2, 1000); > > > data.setValue(0, 3, 300); > > > data.setValue(0, 4, 'East'); > > > data.setValue(1, 0, 'Oranges'); > > > data.setValue(1, 1, new Date (1988,0,1)); > > > data.setValue(1, 2, 950); > > > data.setValue(1, 3, 200); > > > data.setValue(1, 4, 'West'); > > > data.setValue(2, 0, 'Bananas'); > > > data.setValue(2, 1, new Date (1988,0,1)); > > > data.setValue(2, 2, 300); > > > data.setValue(2, 3, 250); > > > data.setValue(2, 4, 'West'); > > > data.setValue(3, 0, 'Apples'); > > > data.setValue(3, 1, new Date(1988,1,1)); > > > data.setValue(3, 2, 1200); > > > data.setValue(3, 3, 400); > > > data.setValue(3, 4, "East"); > > > data.setValue(4, 0, 'Oranges'); > > > data.setValue(4, 1, new Date(1988,1,1)); > > > data.setValue(4, 2, 900); > > > data.setValue(4, 3, 150); > > > data.setValue(4, 4, "West"); > > > data.setValue(5, 0, 'Bananas'); > > > data.setValue(5, 1, new Date(1988,1,1)); > > > data.setValue(5, 2, 788); > > > data.setValue(5, 3, 617); > > > data.setValue(5, 4, "West"); > > > > > var chart = new > > > $wnd.google.visualization.MotionChart(chartDiv); > > > var options = {}; > > > options['state'] ='{"iconKeySettings":[],"stateVersion": > > > 3,"time":"notime","xAxisOption":"_NOTHING","playDuration": > > > > > > 15,"iconType":"BUBBLE","sizeOption":"_NOTHING","xZoomedDataMin":null,"xZoomedIn":false,"duration": > > > {"multiplier":1,"timeUnit":"none"},"yZoomedDataMin":null,"xLambda": > > > 1,"colorOption":"_NOTHING","nonSelectedAlpha":0.4,"dimensions": > > > {"iconDimensions": > > > []},"yZoomedIn":false,"yAxisOption":"_NOTHING","yLambda": > > > 1,"yZoomedDataMax":null,"showTrails":true,"xZoomedDataMax":null};'; > > > options['width'] = 600; > > > options['height'] = 400; > > > > > chart.draw(data, options); > > > }-*/; > > > > > private void motionChartLoaded() { > > > verticalPanel.add(new Label("Motion Chart")); > > > SimplePanel motionPanel = new SimplePanel(); > > > nativeMakeMotionChart(motionPanel.getElement()); > > > verticalPanel.add(motionPanel); > > > } > > > } > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
