Release Notes

1.7.0 (Sept 10th, 2024)​

New Features​

  • Fixed lines can now be added to category charts. This beta functionality can be accessed by enabling the EnabledBetaFeatures property on RevealSdkSettings. The fixed lines section in the editor can use data fields, or one of the highest, lower, average, or fixed value aggregate specialty fields.
  • Added support for dates in visualization filter API. For example, when you have a date-based visualization filter, such as "Last 7 days", you can use the following code to check the date range that the filter evaluated to by checking the From and To properties of the returning RVDateRange object.
var dateRange = revealView.Dashboard.Visualizations[0].Filters[0].DateRange;
  • Server side grid paging is now available without requiring the EnableBetaFeatures flag in RevealSdkSettings. Paging is supported in the following providers: SQL Server, MySQL, BigQuery, PostgreSQL, SyBase, Athena, and Oracle. The providers that support stored procedures will have grid paging disabled when a stored procedure is selected as these can't be queried like tables to return a range of rows. Additionally, paging is not available when processing data on server is false, as well as when using blended data.
  • Added visualization-level descriptions. When editing a visualization, you can now enter a description if desired.
  • Visualizations now automatically support dashboard linking. The default functionality can still be overridden using the instructions from the Linking Dashboards topic.
  • Visualizations can now individually be exported to PDF through their overflow menu when maximized.
  • The filter summary page can now be hidden in exports by setting the IncludeFiltersSummaryPage property on the ExportOptions object.
  • The background overlay when clicking overflow menus or filter search boxes is now lighter.
  • Added the ability to define hidden fields in Grid visualization, which can be used to define a URL or dashboard link.
  • (Beta) Compare filtered data within the same visualization. The series tooltip includes an option to filter by the selected value. The rest of the visualization will display both the filtered values and the original ones for easy comparison. In this release support was added for funnel, treemap, and gauges. This functionality is currently supported in the following chart types: Column, Bar, Line, Time Series, Area, Step Area, Spline, Stacked Column, Stacked Area, Stacked Bar, Funnel, Treemap, and Gauges. To enable this functionality, set HighlightedFilteringEnabled to true on the RevealView.
  • Windows Integrated Authentication is now supported in the Sql Server Analysis Services data source. To enable it, return a new instance of RVIntegratedAuthenticationCredential in your 'IRVAuthenticationProvider' implementation.
  • Sql Server Analysis Services data sources now support the EffectiveUserName property, which makes it possible to impersonate the given user. The property can be leveraged to achieve single sign on, e.g. by setting the property in the IRVDataSourceProvider implementation with the value of the current user, as set in the userContext.

Bugs​

  • Cached files were not removing .tmp file after adding an entry to the Reveal cache.
  • Configured sorting in the value or label field not reflected in Pie visualization.

1.6.7 (June 26th, 2024)​

New Features​

  • Added API to programmatically access visualization filters (aka Quick Filters) and modify their selected values.
//Add a selected value, specified by index from the list of available values, to a field given its name.
async Task AddSelValueToFilter(string fieldName, int valueIdx)
{
	var flt = RevealView.Dashboard.Visualizations[0].Filters.GetByFieldName(fieldName);
	var filterSelValues = flt.SelectedValues.ToList();
	var filterValues = (await flt.GetFilterValuesAsync()).ToList(); //Retrieve the selectable values for the filter
	filterSelValues.Add(filterValues[valueIdx]); //Add the specified value to the selection
	flt.SelectedValues = filterSelValues;
}
  • (Beta) Compare filtered data within the same visualization. The series tooltip includes an option to filter by the selected value. The rest of the visualization will display both the filtered values and the original ones for easy comparison. Currently supported in the following chart types: Column, Bar, Line, Time Series, Area, Step Area, Spline, Stacked Column, Stacked Area, Stacked Bar. To enable this functionality, set HighlightedFilteringEnabled to true on the RevealView.
  • (Beta) Visualization toolbar was added to quickly access trend-lines, labels, zooming, etc. To enable this functionality, set EnableNewToolbar to true on RevealSdkSettings.
  • Removed the ability to provide a custom query client-side on SQL-based data sources.

    {
        InitializeComponent();

        revealView.DashboardChanged += RevealView_DashboardChanged;
    }

    private void RevealView_DashboardChanged(object sender, DashboardChangedEventArgs e)
    {
        // Access the old and new dashboard
        var oldDashboard = e.OldValue;
        var newDashboard = e.NewValue;

        // Implement your logic here
        Console.WriteLine($"Dashboard has changed from {oldDashboard.Title} to {newDashboard.Title}");
    }
}
  • Tables in the data source dialog are now sorted alphabetically. This change applies to connectors for: SQL Server, MySql, Postgres, Redshift, Oracle, and Snowflake.
