Instead of using parameters, allow users to change the values and measures of a visual by choosing from a list of predefined list of items. Example 1: Imagine I have a bar chart with total sales as the measure. I need to use a parameter to change it to a per capita measure. Allow users to change this inside the visual by clicking on the label. This could also allow distinct formatting for each measure, like allowing decimals on per capita's and whole numbers on dollars in the data labels. Example 2: Imagine I have a stacked column chart showing patient's appointments with the date on the x-axis and the appointment type (initial visit, follow up visit, nurse visit, exam, etc) in the legend. Allow users to change the field in the legend to an appointment status (patients seen, cancelled, rescheduled, etc). Allow users to change the date in the x-axis to the office the appointment occured at.
