Dynamic charting

[#1]

Hi all

I am working on a requirement where we need to create a chart which dynamically adds/removes dimensions or calculations based on selections made. I have seen a sample dynamic charting app but it involves heavy macros and i am not familiar with VB.

What i need to do is, say (Period Count) is my selection.

For Period Count = 5, the chart shall display the following,
ExpressionA = sum({<CURVE_POINT_FACTORS._PERIOD = {'0'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))
1= sum({<CURVE_POINT_FACTORS._PERIOD = {'1'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))
2= sum({<CURVE_POINT_FACTORS._PERIOD = {'1'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))
.....

5= sum({<CURVE_POINT_FACTORS._PERIOD = {'5'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))

For Period Count = 3, the chart shall display the following,
ExpressionA = sum({<CURVE_POINT_FACTORS._PERIOD = {'0'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))
1= sum({<CURVE_POINT_FACTORS._PERIOD = {'1'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))
.....

3= sum({<CURVE_POINT_FACTORS._PERIOD = {'3'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))

Sample screenshot above is how the straight table chart should look like but when i select period =5, i am supposed to dynamically see 5 more additional columns IMM1, IMM2, IMM3, IMM4, IMM5.

Can anyone out there help?

Thank you

So you're basically just selecting how many of the expressions to show?

Put a conditional show on each expression. For instance, for expression IMM3:

IMM_Period_Count >= 3

But looking at your data, it looks like CURVE_POINT_FACTORS._PERIOD ought to just be selectable and a dimension. Not sure why you're using set analysis and dynamically showing expressions here. It seems like a lot of trouble to do something that should be very simple with another dimension.

Hello John

Thanks for your input. Yes I have thought of using conditional show, however that will require the expression to be created beforehand, and need to know how many periods are there, and then put a conditional show.

If i want to do it dynamically to automatically create the expression, just based on my period count, do i need to create a loop or some sort for i=i to selectedperiod_count, create expression:

IMM($i)sum({<CURVE_POINT_FACTORS._PERIOD = {'$i'}>} (QTY_ORIGINAL * CURVE_POINT_FACTORS._FACTOR))

Is it possible?

It should be possible, but it sounds like it would be a fairly complicated macro.

What is preventing you from just adding CURVE_POINT_FACTORS._PERIOD as a dimension?
