Hi,
Does anyone know a simple solution to fit two different line measures with different date dimensions from each other into one graph? I am trying to visualize the cumulative returns (daily for midweek data) with the corresponding Model score (+/- weekly) for a stock.
I thought a simple combo chart will do the work, but because both measures use different dimensions (frequent vs less frequent dates) only either one will be shown correctly. My solution is to reload the less frequent measure (Model score) for the dates for which no model score is available. In this way there would be the same amount of data available for both measures and hopefully this will result in the graph I am looking for.
As this is a brand new territory for me, could someone please help me creating this script if this indeed seems the correct solution?
Thank you for your time.

Summary: Combo chart only supports one dimension for multiple measures. How to fit two different line measures with two different date dimensions into one graph? Dimensions are called "Dates" (daily for midweek data) for returns and "DatesCockpit" (+/- weekly) for Model scores.
Anjos, excuse me for my late responds. You are right on the frequency of DatesCockpit and Dates. Find bellow the new pictures using your code:
For some reason the frequency of Dates also became also weekly, instead of daily (see the second chart). The model score in the above figure is correct, the returns in the top figure are correct on a weekly basis, but I'd like to have them on a daily basis. As you can see in my earlier comment the daily returns (lowest figure) give a different outcome than the weekly returns.
Hi sebhesjuan
Since I am a latecomer to this thread and I have too much time to go over what has already happened, I would ask you to very briefly explain what is needed and may be the exact numbers you are looking to get? An Excel file which shows the numbers for the two lines would be great.
Best,

Hi Sunny T,
In short, I need a combo chart representing two different series (Returns and Model Scores). The problem is that both series have a different frequency of dates for which numbers are available (+/- daily vs +/- weekly respectively). I have added two excel files containing the required numbers. In the "Combo Chart with correct Model Scores"-file the cumulative return is not represented well due to the difference in date frequency. Please let me know if anything remains unclear after this explanation.
With kind regards,
Sebastian
I understand the required output, now the question is what would you want to see in your combo chart? Daily Data or Weekly Data?
In my combo chart I would like to see the same frequency as used for the returns (+/- daily).
However, the model score is on a weekly basis, which causes the problem. I originally thought if the model score could somehow be copied to the same frequency of dates as the return data, that this might provide the correct solution.
That is what I am trying to understand. Right now you have this
DatesCockpit | (Model) |
14-05-2014 | 123% |
19-05-2014 | 138% |
This would show on a daily chart like this?
DatesCockpit | (Model) |
14-05-2014 | 123% |
15-05-2014 | 123% |
16-05-2014 | 123% |
17-05-2014 | 123% |
18-05-2014 | 123% |
19-05-2014 | 138% |
or something else?
Yes, exactly. Please note that the dates of "Dates" is not exactly on a daily basis. Weekend are often omitted.
I am looking at your first attachement (2nd one only have weekly data for returns, so had to go to 1st attachment). Within that I am unable to get 123% for 14-05-2014? How are you getting this? Its not the Avg() or Sum() of all rows, right? What kind of aggregation do I need to get this 123%?
Try this for model with Dates as dimension
Aggr(If(Floor(Dates) >= Floor(WeekStart(DatesCockpit)) and Floor(Dates) <= Floor(WeekEnd(DatesCockpit)), Model), Dates, DatesCockpit)
In table, it would look like this:

Hi Sunny,
I should have stated that the Model score is not related to the return of the stock whatsoever. These are fixed numbers computed based on much different data which are not related to the returns at all.
Optimally, the combo chart should therefore give an impression to what extent the Model score indeed predicts the returns in the future.
Excuse me for the inconvenience.
