Parameters in Tableau
- 1. Letâs learn Tableau Data Visualization Software Version 2019.3.0 Made By: Kanika Nagpal LinkedIn Id: https://www.linkedin.com/in/kanika-nagpal/
- 2. Parameters A parameter is a global placeholder value such as a number, date, or string that can replace a constant value in a calculation.
- 3. What are Parameters? Parameters are user-generated values, that allows user and his audience to choose the inputs of calculated fields. Parameters allow user to use aggregated values that arenât available in the data and incorporate these values into dashboard reports. After creation, end user can control the input to see the results of the effect of parameter.

- 6. Dataset : US_Superstore Superstores are very large supermarkets or shops selling household goods and equipment. Superstores are usually built outside city centres away from other shops. The original dataset is available on Kaggle. List of columns used are as follows :- â˘Sub Category â˘Profit â˘Sales
- 8. Step 1: Create a Parameter ⢠Create a Bar graph using âSub Categoryâ and âSalesâ. Drag âProfitâ in color card. ⢠Click the drop down beside the âDimensionsâ section. ⢠Select âCreate ParameterâŚâ and a dialogue box will appear. Name it âSelect Optionâ. ⢠Under âPropertiesâ section, select âData typeâ as âStringâ and âAllowable Valuesâ as âListâ. ⢠In âList of valuesâ section, under âValuesâ write first âSalesâ and next âProfitâ. ⢠Click âOkâ and new section named âParametersâ is added below âMeasuresâ section and under it âSelect Optionâ field is created. ⢠Under âParametersâ section, right click on âSelect Optionâ and select âShow Parameter Controlâ.
- 9. Step 2: Define action to Parameter ⢠Click the drop down beside the âDimensionsâ section. ⢠Select âCreate Calculated FieldâŚâ and a dialogue box will appear. Name it âChoose Optionâ and write the formula as follows: Case [Select Option] When âSalesâ Then [Sales] When âProfitâ Then [Profit] End ⢠Click âOkâ and a âChoose Optionâ field is created under âMeasuresâ section.
- 10. Step 3: Integrate Parameter with action ⢠Click the drop down of âSub Categoryâ in âRowâ shelf. ⢠Select âSortâ and a dialogue box will appear. ⢠Under âSort Byâ, select option âFieldâ. ⢠Under âSort Orderâ, select âDescendingâ. ⢠Under âField Nameâ, select âChoose Optionâ. ⢠Close the dialogue box after the above are made. On selecting âSalesâ from the âChoose Optionâ parameter control, the data gets sorted in descending order basis the âSalesâ. And on selecting âProfitâ from the âChoose Optionâ parameter control, the data gets sorted in descending order basis the âProfitâ. Click next to check out the resulting graphs.
- 13. Different ways to use Parameters
- 14. Dynamic X axis or Y axis ⢠Dynamic X axis or Y axis: Using parameter user can change the Measure of X axis or Y axis. This is very helpful in case where user is unsure about which Measure user wants to see in any axis. Also, it provides the flexibility to user to analyze the same chart with different axis. ⢠Example: Consider a scatter chart, where X axis is Sales, but Y axis can be Discount, Profit or Quantity.
- 15. ⢠Filtering with parameter: Parameters can also be used to filter the data. It provides user the flexibility to change the filter Dimension depending upon the selection value of filter. ⢠Example: Consider the case where the requirement is to filter the data basis either product or sub-category or category. So in this case instead of providing 3 different filter for each type, using parameter and calculation (based on parameter) user can provide one filter. Filtering with Parameter
- 16. ⢠Use of Parameter across different data sources: Filters are specific to data sources but Parameters are common to all data sources and can be reused across the Workbook. ⢠Example: Consider a bar chart across countries from data source1 and another scatter chart showing counties across sales and profit from data source2. Now, if user wants to apply filter which is common for both charts, then using parameter it can be done easily. Parameter across data sources
