Problem $3$: Recreate the following viz: In this problem, you will need to use Parameters and Calculated Fields. Upload the $$Advancement$\_$donations$\_$and$\_$giving$\_$Combined.xlsx$$ file to Tableau. $$ Create two parameters $$ Min Gift Level $$ Major Donation Cut$-$off $$ Use Logarithmic axis and uncheck $$Include Zero$$ when plotting the Donation vs Date $$ Add a Reference Line at Major Donation Cut$-$off. Hint: Be careful with which axis you add the reference line to; you want to add it to the donation axis, not the date axis. $$ Use the parameters to do the following: $$ Created a calculated field to show only gifts above the Min Gift Level. Hint: Use the NULL function $$ Create a calculated field to highlight large donors $($those above the Major Donor Cut$-$ff$).$ Create a calculated field that can be used to label the Subcategory Allocation of large gifts
