Help with using variables in an Inline load for use with a Pick function

kdmarkee — Fri, 15 Nov 2024 23:45:56 GMT

How can I create the chart below by using a dimension that takes the user’s chosen “As of Date” value (in this example the user choose an As of Date of 11/1/2020) and then show the first of the month for each month going back 3 months. (My real life scenario will go back 12 months, but using 3 for now in the example.) So in my example, I would need plot 4 to actually be 11/1/2020, 3 to be 10/1/2020, 2 to be 9/1/2020 and 1 to be 8/1/2020. “As of Date” is always a single value so it cannot be used as a dimension like a typical calendar field.

To create the chart above I used the following in my script

DimDummy:
LOAD * Inline [
DimDummy
1
2
3
4
];

And in my chart object as an expression, I then can control each value for each dimension plot 1-4:

=Pick(DimDummy,
Num([3moback] / [Avg Daily Charges],'#,##0'),
Num([2moback] / [Avg Daily Charges],'#,##0'),
Num([1moback] / [Avg Daily Charges],'#,##0'),
Num([as of selected] / [Avg Daily Charges],'#,##0')
)

I cannot seem to make a DimDummy Inline table to reflect the dynamic dates I need. I tried to establish variables (ie, AddMonths(AsOfDate, -2) would represent my plot number 3) and then use the variables in the inline load but it is not working (for starters, I cannot get past the comma in the variable giving me problems even if I try chr(44) in its place).

How would I do this or is there a better way to achieve my chart? Thanks.

That won't work because the calculations are dynamic based on selections and therefore cannot be done in script, which is what I think you are suggesting. I did actually find a rather simple solution by using an IF statement in a calculated dimension which basically builds my labels/plots so I can use my chart expression along with it... like so...

=Date(
if(DimDummy=1, AsOfDate,
if(DimDummy=2, AddMonths(AsOfDate, -1),
if(DimDummy=3, AddMonths(AsOfDate, -2),
if(DimDummy=4, AddMonths(AsOfDate, -3)
))))
)
