Series data is optional in Stream chart. Series in a Stream chart, if included, are centered. They do not share the same baseline and do not overlap. These 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 Funnel chart](/docs/s/article/360043429513 "Stream Funnel Graph") (classified in the Chart Picker as a Pie/Funnel chart rather than an Area chart) but is shown horizontally rather than vertically. The following example shows a Stream chart without series data: stream_without_series.png Whereas the next example shows the same chart with series data applied: stream_with_series.png ## Powering Stream Charts Stream 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 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 chart: ## Customizing Stream Charts You can customize the appearance of a Funnel chart by editing its **Chart Properties**. For information about all chart properties, see [Chart Properties](/docs/s/topic/0TO5w000000ZaodGAC "Chart Properties").
