Workflow Control - Exercise
Activity III: CASE Switch Extend the workflow below with a switch that only creates one type of visualization. - Create a Single Selection Configuration node with the possible values "scatter" and "bar" - Use the CASE Switch Start node and add a data input port. The node activates the top/bottom branch depending on theselection scatter/bar (Use the "...(index)" flow variable to define the active port)- Combine the outputs of the two branches with the CASE Switch End node. Add a Data output port, and that adds two data inputports as well. Activity I: Write Multiple Excel Sheets into an Excel FileGoal: Build a loop that will create an Excel file with separate Excel sheets for the records of different products. - Read the table CurrentDetailData.table (Table Reader node) - Start a loop that handles the records for the different products in separate iterations (Group Loop Start node) - For each product write one Excel sheet into a single Excel file (Excel Writer node) Tip: Control the flow variable sheet_name in the Flow Variable tab by using a flow variable created by the Group Loop Startnode - Close and execute the loop (Variable Loop End node) Activity II: Concatenate Multiple Excel SheetsGoal: Create a loop that reads and concatenates all the sheets in an Excel file. - Create a table that contains all sheet names (Read Excel Sheet Names node) - Start a loop that iterates over the sheet names (Table Row to Variable Loop Start node) - Read the Excel sheet with the sheet name in the current iteration (Excel Reader node) Tip: Use the flow variable created by the Table Row to Variable Loop node to control the setting sheet_name in the FlowVariable tab - Close the loop and concatenate the tables from the different iterations (Loop End node) Customer data Image To Table Image To Table Scatter Plot Bar Chart Table Reader Activity III: CASE Switch Extend the workflow below with a switch that only creates one type of visualization. - Create a Single Selection Configuration node with the possible values "scatter" and "bar" - Use the CASE Switch Start node and add a data input port.
