Unlike other pie-type charts in Domo, Stream Funnel charts allow you to include series data (though this is not required). Legends are not shown in a Stream Funnel chart unless series data is included. Stream Funnel charts also do not show value data except upon mouse-over. Therefore they are most effective for showing relative differences between stages rather than representing exact amounts. This chart type is exactly the same as a [Stream chart](/docs/s/article/360043429533 "Stream Graph") (classified in the Chart Picker as an Area chart rather than a pie-type chart) but is shown vertically rather than horizontally. The following example shows a Stream Funnel without series data: stream_funnel_without_series.png Whereas the next example shows the same chart with series data applied: stream_funnel_with_series.png Also unlike other types of Funnel charts, drill path is available in Stream Funnel charts. For more information about drilling, see [Adding Drill Path to Your Chart](/docs/s/article/360042924094 "Adding Drill Path to Your Chart"). ## Powering Stream Funnel Charts Stream Funnel charts require two columns or rows of data from your DataSet—a category column or row containing the names of each stage, and a value column or row containing the corresponding values for each stage. You can also add a column containing series data if you want. For information about value, category, and series data, see [Understanding Chart Data](/docs/s/article/360043428693 "Understanding Chart Data"). In the Analyzer, you choose the columns containing the data for your Stream Funnel chart. For more information about choosing data columns, see [Applying DataSet Columns to Your Chart](/docs/s/article/360043428713 "Applying DataSet Columns to Your Chart"). For more information about formatting charts in the Analyzer, see [Visualization Card Building Part 2: The Analyzer](/docs/s/topic/0TO5w000000ZaoUGAS "KPI Card Building Part 2: The Analyzer"). The following graphic shows you how the data from the category, value, and series columns in a typical column-based spreadsheet is converted into a Stream Funnel chart: stream_funnel_spreadsheet_example.png ## Customizing Stream Funnel Charts You can customize the appearance of a Stream Funnel chart by editing its **Chart Properties**. For information about all chart properties, see [Chart Properties](/docs/s/topic/0TO5w000000ZaodGAC "Chart Properties").
