How to 'input' a required selection ?

[#1]

Hi,

In my dashboard, at the script side, I am calculating a calender table with columns like Year, Quarter and Month

The customer requirement at UI now changed and they want a filter of the following sort,

..that is, they want in a multibox, with two dropdowns. 1)Period 2)Range

In period dropdown, they want to see the values Year, Quarter and Month

In range dropdown, they want to see the values from 1-10

Now on selecting say Year in the Period dropdown and on selecting say 5 from the Range dropdown, they want the dashboad selection to be set for last five years.

I have no idea how to implement this without altering the current way the data is structured at the script side.

If anyone can guide me with suggestions/ideas..that would be of great help.

Thanks,

Vishnu

vishnu,

why not use the range as a parameter that will act somthing like a 'top n' values?

in dimension limits, you select top n limitation and put there a parameter

then, you create a slider or a drop down list with only number and when selecting a number it will be put into the parameter allowing to calculate the top n years in your case....

It is easy to implement with variables.

Instead of multibox add input box with two new variables to select Period and Range (use "predefined values in drop-down" as constrain).

Then create a variable vRangeStart to store required starting date of dashboard data.

For this variable add expression to recalculate the date every time user changes Period or Range.

Something like this:

=date(

  if(vPeriod = 'Year', makedate(year(today())-vRange),

  if(vPeriod = 'Month', addmonths(monthstart(today()), -vRange),

  if(vPeriod = 'Quarter', addmonths(quarterstart(today()), -vRange * 3))))

  )

In dashboard expressions add if-statement or set-analysis syntax to always limit the data to

Date >=vRangeStart.
