Docs are available before the release of Designer Cloud so you can get a sneak peek. This content might change between now and the official release.
One Tool Example
Tile has a One Tool Example. Visit Sample Workflows to learn how to access this and many other examples directly in Alteryx Designer Cloud.
Use Tile to assign a value (tile) based on ranges in the data. The tool does this based on the user specifying 1 of 5 methods.
2 columns are appended to the data:
- Tile_Num is the assigned tile of the row.
- Tile_SequenceNum is the row number of the row's position within the Tile.
Configure the Tool
Tile Method: Select the range pattern used to assign tile value.
Assigns tiles to cover a range of values where each tile has the same total of the Sum field based on the sort order of the incoming rows.
Create Tiles with Equal Total Values
The total of the Sum field is as close as it can be for each tile without breaking a record.
- Numeric Column to Sum: Specify how many groups to assign to the data.
- Column to Sum: Specify the column to tile that results in ranges where the sum of this number is equally distributed across the tiles.
- Column to Sort By (Optional): If you select a column from this dropdown list, the data is sorted on the specified column before it is assigned to a tile. If no field is specified, the rows are assigned to tiles based on their incoming sort order.
Input rows are divided into the specified amount of tiles so that each tile is assigned the same amount of rows.
Divide Records Equally
- Select the Number of Tiles to assign to the data.
- Don't Split Tile on Column (Optional): If you select a column from this dropdown list, a tile is not split across this column. If no column is selected, the tile number takes preference over the specified column data, thus potentially splitting groups.
- Column to Sort By (Optional): If you select a column from this drop-down list, the data will be sorted (in descending order for numbers and ascending order for all other column types) on the specified column before it is assigned to a tile.
The number of rows in the input might not be equally divisible by the number of tiles you specify. This is based solely on the row's position in the input file unless the Sort column is specified.
Creates tiles based on the Standard Deviation of the values in the specified column. The tiles assigned indicate whether the row's value falls within the average range (=0), above the average (1), or below the average (-1), etc.
Sort Rows by Variance from the Average
The tile value represents the mean of the data range. The tile numbers explain the range directly. The range always starts at -0.5 and ends at +0.5:
|0||-0.5 to 0.5|
|-1||-1.5 to -0.5|
|1||0.5 to 1.5|
- Numeric Column to Group (Must be Numeric): Choose the column to tile by. This column must contain a numeric value.
- Select the naming convention applied to the output field:
- Don't Output Column with Tile Labels: No additional output column name is generated.
- Output Column with Tile Labels: Outputs tile labels only. Descriptors include Average, Above Average, High, Extremely High, Below Average, Low, and Extremely Low.
- Output Column with Verbose Tile Label: Outputs tile labels and the corresponding ranges. For example, High (12750 to 155000).
For each unique value in a specified column or columns, a unique tile is assigned. If multiple columns are specified, a tile is assigned based on that combination of values.
Create Tiles for Unique Values
- Create Unique Tiles From: Check the box of the column or columns to tile by.
- If the Sort Output checkbox is checked, the table is automatically sorted by the field or fields you specified for the tile.
The user can specify the cutoffs for the tiles by typing a value on a new line for each range.
Set Up Rules Manually
- Numeric Column to Group (Must be Numeric): Select the column to tile by.
- Enter Upper Limits for Each Tile: Enter each tile's upper limit on a new line in the box provided.
Tiles are applied in Manual mode but the rows are not sorted. You must add a Sort tool and specify the columns to sort by, if that is how you want the data displayed.
