Right-click on the object and ensure that Show Missing Values is checked.We are going to start building our Worksheet: But using these created Calculated Fields, we are now going to build our Worksheet. I would suggest going through each line to try and understand what is going on here. We have individual logical to draw the A, A and AnB parts of our Venn Diagram.This is based on the P_Outer parameter and how we are drawing our outer circle components. We are finding the point where we bend the circle in as opposed to being completed.Suffice to say, what we are doing with the X and Y Calculated fields looks quite crazy, however: TC_Circle Distance from Center WINDOW_MAX(SIN(*PI()/180))Д®LSEIF > (180-) AND < (180+) THEN Right click on Path, go to CreateВ and select BinsвЂ¦.Note: We will use this parameter to control the amount of overlap between our two circles. Add a Value of 35 and Display asВ to Maximum.Add a Value of 40 and Display asВ to Large.Add a Value of 45 and Display asВ to Medium.Add a Value of 50 and Display as to Small.In Allowable values select List and enter the following values:.With our data set loaded into Tableau, we are going to create the following Parameter, Calculated Fields and Bins: Note: we need two records for each stage as we are going to be drawing polygons and using densification to get more points on our canvas. Load the following data into Tableau Desktop / Public. Note: As always never choose a data visualisation type and try to fit your data into it, instead, understand your data and choose the best visualization for your data consumers.
