Before learning how to create charts, we'll learn how associative logic works. Associative logic is a key functionality in Qlik Sense – it allows a business user without technical knowledge to explore the data.
In the following screenshot, we'll see the Qlik Sense main screen in the Edit mode. The screen is divided into three areas. In the center pane, you can see the sheet you're developing; the current screenshot shows an empty sheet. The right-hand pane shows the properties of the active object. In this case, the right-hand pane shows the sheet properties – Title, Description, and Thumbnail. The left-hand pane has a tab row with three options – Charts, Fields, and Master items; in this chapter, we'll use Charts and Fields, as shown here:
From the left-hand side tab row, select Fields; you'll see all fields in alphabetical order. Drag the Channel_Desc field and drop it into the central area, as shown in the following screenshot:
This action will add a filter pane to your new sheet. The filter pane has four arrows – up, down, right, and left. Use these arrows to move and resize the filter pane. You will be able to move and resize all visual objects in Qlik Sense, as shown here:
After placing Channel_Desc, add two fields as pane filters in your sheet – Region_Desc and Customer_ID. Finally, click on the Done button to exit the edit mode, as shown in the following screenshot:
You've learned in Chapter 1, Getting Ready with Predictive Analysis, how to use a filter in Qlik Sense. The following screenshot illustrates that the two filters that have been selected, turned green in color. Use these two filters to answer the question: which retail customers do I have in Porto?
You've selected Retail and Porto in the Channel_Desc and Region_Desc filters. In the Customer_ID pane, you can see some customers with a white background and some customers with a dark grey background. The customers with the white background are customers associated to Retail and Porto, so these customers are Retail customers from Porto. The dark grey customers are not related to Porto and Retail, so they are not Retail customers from Porto.
Using filters, a business user with no technical knowledge can ask everything about his dataset.
