Operating system requirements: iOS 5.0 or later.
Mobile device: iPad.
This example displays an express report bubble chart, for which a legend is hidden. After starting the example the development environment console displays the following information:
Timeline value.
Name of file with bubble chart settings.
Names and keys of color, size, X and Y axis metrics.
Number of bubble chart settings.
Number of values of data series and specific series value for color, size, X and Y axes.
Series label with specified identifier.
Key of the metric dimension used at the moment.
Number of fixed dimensions.
Name of territory and calendar dimensions.
Name of observations objects.
Executing the example requires to place the following code in the body of the executeExample method of the ViewController class (see the Displaying of Express Report section):
// Get bubble chart data view controller
MAExpressAnalysisReportViewController *contr = (MAExpressAnalysisReportViewController*)m_controller;
NSArray *controllers = [contr dataViewControllers];
MABubbleDataViewController *bubbleDataViewController;
for (int i = 0; i < controllers.count; i++){
if([controllers[i] isKindOfClass:[MABubbleDataViewController class]]){
bubbleDataViewController = controllers[i];
// Display bubble chart
[contr setDataViewMode:kViewModeBubble];
// Get bubble chart data source
BubbleDataViewDatasource *bubbleDataSource = bubbleDataViewController.bubbleDataSource;
// Get bubble chart data source and display timeline value
id<ChartDataSource> chartDataSource = bubbleDataViewController.dataSource;
printf("Timeline value: %d\n", [chartDataSource currentTimestamp]);
// Display name of file with bubble chart settings
printf("Name of file with bubble chart settings: %s\n", [[bubbleDataViewController settingsPlistName] UTF8String]);
// Display name and key of metric that determines bubble color
if(bubbleDataSource.getColorMetricName != NULL) {
printf("Name of metric that determines bubble color: %s\n", [[bubbleDataSource getColorMetricName] UTF8String]);
printf("key of metric that determines bubble color: %lld\n", [bubbleDataSource colorMetricKey]);
}
// Display name and key of metric that determines bubble size
if(bubbleDataSource.getSizeMetricName != NULL) {
printf("Name of metric that determines bubble size: %s\n", [[bubbleDataSource getSizeMetricName] UTF8String]);
printf("Key of metric that determines bubble size: %lld\n", [bubbleDataSource sizeMetricKey]);
}
// Display name and key of metric that determines X axis values
if(bubbleDataSource.getXMetricName != NULL) {
printf("Name of metric that determines X axis values: %s\n", [[bubbleDataSource getXMetricName] UTF8String]);
printf("Key of metric that determines X axis values: %lld\n", [bubbleDataSource xMetricKey]);
}
// Display name and key of metric that determines Y axis values
if(bubbleDataSource.getYMetricName != NULL) {
printf("Name of metric that determines Y axis values: %s\n", [[bubbleDataSource getYMetricName] UTF8String]);
printf("Key of metric that determines Y axis values: %lld\n", [bubbleDataSource yMetricKey]);
}
// Display number of bubble chart settings
SNDictionary settings = [bubbleDataSource dumpSettings];
printf("Number of bubble chart settings: %d\n", settings->count());
// Display number of data series values for color, size, X and Y axes
if(bubbleDataSource.hasColorData)
printf("Number of data series values for color: %d\n", bubbleDataSource.colorValues.count);
if(bubbleDataSource.hasSizeData)
printf("Number of data series values for size: %d\n", bubbleDataSource.sizeValues.count);
printf("Number of data series values for X axis: %d\n", bubbleDataSource.xValues.count);
printf("Number of data series values for Y axis: %d\n", bubbleDataSource.yValues.count);
// Get data series identifier and display its label
NSString *seriesID = bubbleDataSource.seriesIDs[0];
NSString *seriesTitle = [bubbleDataSource seriesTitleWithID:seriesID];
printf("Data series label with the identifier %s: %s\n", [seriesID UTF8String], [seriesTitle UTF8String]);
// Display data series value for color
printf("%s %f\n", "Data series value for color", [[bubbleDataSource colorSeriesWithID: seriesID][0] doubleValue]);
// Display data series value for size
printf("%s %f\n", "Data series value for size", [[bubbleDataSource sizeSeriesWithID: seriesID][1] doubleValue]);
// Display data series value for X axis
printf("%s %f\n", "Data series value for X axis", [[bubbleDataSource xSeriesWithID: seriesID][2] doubleValue]);
// Display data series value for Y axis
printf("%s %f\n", "Data series value for Y axis", [[bubbleDataSource ySeriesWithID: seriesID][3] doubleValue]);
// Display key of currently used metrics dimension and number of fixed dimensions
printf("key of currently used metrics dimension: %lld\n", [bubbleDataSource currentMetricsDimensionKey]);
printf("Number of fixed dimensions: %d \n", bubbleDataSource.fixedDimensions->count());
// Display data source dimension names
printf("Territory dimension name: %s\n", [bubbleDataSource observationDimension]->name()->UTF8String());
printf("Observation object names: %s\n", [bubbleDataSource metricsDimension]->name()->UTF8String());
printf("Calendar dimension name: %s\n", [bubbleDataSource timelineDimension]->name()->UTF8String());
// Display timeline labels
NSArray *timeAxisTitles = [bubbleDataSource timeAxisTitles];
printf("Timeline labels: ");
for (int i = 0; i < timeAxisTitles.count; i++) {
printf("%s; ", [timeAxisTitles[i] UTF8String]);
}
// Display first element value of metrics dimensions names dictionary
NSDictionary *dimKeys = [bubbleDataSource metricsDimensionsKeys];
printf("\nFirst element value of metrics dimensions names dictionary: %s\n", [[[dimKeys allValues] objectAtIndex:0] UTF8String]);
// Display first element value of metrics dimension elements names dictionary
NSDictionary *elDimKeys = [bubbleDataSource metricsDimensionElementsKeys];
printf("First element value of metrics dimension elements names dictionary: %s\n", [[[elDimKeys allValues] objectAtIndex:0] UTF8String]);
return;
}
}
NSLog(@"Bubble chart data view is not available");
It is also required to replace the code in the static example file MAExpressAnalysisReportViewControllerDelegateImpl.mm in the initWithOlapReport: method in the block:
if (self.isBubbleEnabled)
with the following code:
// Get report settings
SNDictionary bubbleOlapPlist = m_olapReport->storageDictionary()->objectForKey<NDictionary>(BUBBLE_OLAP_KEY);
// Create a report
SPPLOlapReport bubbleOlapReport = NULL;
if (bubbleOlapPlist != NULL) {
bubbleOlapReport = PPLOlapReport::olapReport(m_olapReport->descriptor(), bubbleOlapPlist);
}
// Create a data table
m_bubblePivot = (bubbleOlapReport != NULL) ? PPLPivot::pivot(bubbleOlapReport) : PPLPivot::pivot(m_olapReport);
// Create a data source
m_bubbleDatasource = [[BubbleDataViewDatasource alloc] initWithPivot:m_bubblePivot];
// Create a metric selection controller
m_bubbleElementRoleSelector = [[MAElementDataSourceRoleSelectorViewController alloc] initWithBubbleDataSource:m_bubbleDatasource];
// Get bubble chart settings
SNDictionary bubbleSettings = m_olapReport->bubblesSettings();
// Get dimension element selection settings
SNDictionary selectionSetings = m_olapReport->selectionDictionary();
// Get bubble chart data source settings
SNDictionary bubbleDSSettings = m_olapReport->storageDictionary()->objectForKey<NDictionary>(BUBBLE_DS_KEY);
// Load settings
[m_bubbleDatasource loadSettings:bubbleSettings dataStorageSettings:bubbleDSSettings indicatorEmptySettings:selectionSetings];
And in the MAExpressAnalysisReportViewControllerFactory.mm file in the createReport: method in the block:
if (delegate.isBubbleEnabled)
with the following code:
// Create bubble chart data view controller MABubbleDataViewController *controller = [[MABubbleDataViewController alloc] initWithDatasource:(BubbleDataViewDatasource *)delegate.bubbleDatasource]; // Set title visibility controller.isDataViewTitleVisible = !!delegate.olapReport->title(); // Set controller delegate controller.delegate = report; // Set controller tag controller.tag = kViewModeBubble; // Set value for coefficient of correlation between bubble chart area size and its elements sizes, at which elements must be hidden controller.contentOptimizationFactor = 1; // Hide bubble chart elements that do not fit controller.optimizeOn = YES; // Enable zoom gesture controller.zoomEnabled = YES; // Set settings file name controller.settingsPlistName = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ? @"settings_ea_ipad.plist" : @"settings_ea_iphone.plist"); // Add controller to array of controllers [controllers addObject:controller]; // Adds controller to pool of objects, for which links are automatically counted [controller autorelease];
After executing the example the bubble chart with the hidden legend is displayed:
The browser console also displays values of bubble chart settings and its data source:
