You can read tables from a PDF and convert them into a pandas DataFrame. Please note that while we make every effort to keep references to third-party content accurate, the information we provide here might change without notice as content on their website changes.Tabula-py is a simple Python wrapper of tabula-java, which can read tables in a PDF. Viewers can set up their own reports, save their parameter settings, and share views with others.įor information about building views dynamically, see Swap Measures Using Parameters (Link opens in a new window).įor information about the different areas in the Tableau interface in which you can create and incorporate parameters, see Create Parameters and its related topics in the Tableau Help.ĭisclaimer: This topic includes information about parameters from a third-party blog, The Information Lab: Data School. Reset all parameters to None and publish the workbook to Tableau Server. Sort the dynamic dimension fields alphabetically. Test your parameters by selecting fields in the parameter controls.

In this example, Sales is placed on Label on the Marks card. Under Parameters, right-click the parameter and select Show Parameter Control.įrom the Data pane, drag the calculated fields you created to the Columns and Rows shelves.įrom the Data pane, drag a measure to the view. Next, expose the parameter control so users can select the categories they want to display.įor each parameter you created, do the following: Give viewers a way to interact with views The basic formula for each calculated field is the same as in the previous step, except that you reference a different parameter in each CASE statement. Note: ELSE accounts for the None value that you included in the parameter, and it returns an empty string.Ĭreate three more calculated fields, one for each of the additional parameters you created: Parameter name WHEN 'Customer Segment' THEN Ĭonfirm that the status message indicates that the formula is valid, and then click OK.

This article covers only the single data type scenario. You would do this when you build the calculated field, using the STR() function. If you wanted to include a measure such as profit in this list, one option would be to convert the measure to a string value. These are all dimensions of the same data type (string).

Note: This example uses the customer name, customer segment, region, department, and category fields. Complete the list by typing the names of the additional dimension fields that you want to expose through the parameter.This example uses Select Column 1 Heading.įor Allowable Values, select List, type None as the first value in the list, and then press Enter. Name the parameter so that viewers can tell what changing it will do. In the Create Parameter dialog box, complete the following steps: Upper right corner and select Create Parameter. In the Data pane, click the drop-down arrow in the These steps use the Superstore sample to create new parameters.
