Simple pivot table:
In this case, I'm pulling back 5 fields from the database:
Category
Year
Quarter
Numerator
Divisor
2 unfortunate facts. First, the year/quarters drift to provide a rolling 8-quarter view. Consequently, there will usually be 1 full year and 2 partials with their respective quarters. Second, the measures to be displayed are ratios of numerator to divisor. Naturally, Crystal is assuming that I want to divide everything and then total it, which is not correct.
How do you get the pivot table totals to calculate correctly as SUM({Numerator})/SUM({Denominator})? Since there are multiple levels in play, the Sum({Numerator}, {Attribute})/Sum({Denominator}, {Attribute}) doesn't seem to work or I'm missing an extra element to it.
This crosstab is intended to replace a report that individually calculated every cell, and is not viable for long-term maintenance. If the totals can't be corrected, we'll have to revert back to that format.
Once you create a cross tab... you can insert saperate column or row inside the existing column using the option embeeded summary
Right click---> Embeeded Summary ---> insert embeeded summary
This will insert a row as Edit This Formula.
Now on the newly created cell
Right click---> Embeeded Summary ---> Edit Calculation formula
This will open a window there write your division formula.

Im fairly sure what im attempting is not the ideal way to do things due to my lack of knowledge of power BI but here goes:
I have two tables in the form of:
One has the actual power against wind and the other is a reference
I created calculated columns that add a corresponding binned speed to each row (so 1-2, 2-3, 3-4 etc)
I have filters and slicers applied on the page / visual that will keep changing.
What i want is to create a pivot or a grouped table that is changed dynamically based on my filters.
The reason i want this is currently the table ive got has totals that are averaged (because individual row is averaged) but i want a sum of an average by category. If i can have this as a calculated table instead of a visual (picture below) i would likely be able to aggregate this again to get what i want
so on the above table i want to totals to be sum of individual rows. I also want to be able to use these totals to carry out other calculations (simple stuff like total divided by fixed number etc)
I am using Power Bi to produce several reports, one of it is the NPS score for support. However, I am coming across an issue with the clustered column chart. It is showing the value against the total number rather than for each row.
What I want to see if the following (within Excel),
The NPS score is shown as a percentage for each week.
e.g. Week 3 has the Promoter at 95.5% and Detractor at 4.5%
However, when using Power Bi, I am shown the following, which is a Percentage of the grand total, instead of each week.
Using a Matrix, I could see the following as total numbers.
I can copy this Matrix and show it as a Percentage of each Row, which is also correctly showing the results.
I have the dates already set up using a feeder table to allow me to get the week number etc from a date within the main raw data, so they sort in the correct order..
My Chart is using the following table entries
Cal Week and WeekNo are both from the feeder table (Fiscal)
Net Promoter and Count of Case Num are from the RawData table.
How can I get the chart to show the percentages per week instead of the total?
I am also planning to use slicers to filter down further, for example, Regions (which are in the RawData).
I believe I will need to add an extra column to the RawData, but no idea what to put in it and then how to use that in the chart, and still allow it to slice.
Any help would be greatly appreciated.
Thanks

I am trying to show the change in moving average by county on a map.
Currently, I have the calculated field for this:
IF ISNULL(LOOKUP(SUM([Covid Count]),-14)) THEN NULL ELSE
WINDOW_AVG(SUM([Covid Count]), -7, 0)-WINDOW_AVG(SUM([Covid Count]), -14, -7)
END
This works in creating a line graph where I filter the dates to only include 15 consecutive dates. This results in one point with the correct change in average.
I would like this to number to be plotted on a map but it says there are just null values.
The formula is only one part of defining a table calculation (a class of calculations performed client side tableau taking the aggregate query results returned from the data source)
Equally critical are the dimensions in play on the view to determine the level of detail of the query, and the instructions you provide to tell Tableau how to slice up or layout the query results before applying the table calc formula. This critical step is known as setting the “partitioning and addressing” for the table calc, sometimes also as setting the “compute using”. Read about it in the online help for table calcs. You can experiment with using the Edit Table Calc dialog by clicking on the corresponding pill.
In short, you probably have to a dimension, such as your Date field to some shelf - likely the detail shelf, and the set the partitioning and addressing, probably to partition by county and address by state.
If you have more than a couple of weeks of data, then you’ll get multiple marks per county. You may need to decide how to handle that on your map.
I've got a bar chart with three months worth of data. Each column in the chart is one month's data showing the percentage of Rows that met a certain criterion for that month. In the first month, 100% of 2 rows meet the measure. In the second month, 24.2% of 641 rows meet the measure. In the 3rd month, 28.3% of 1004 rows meet the measure. My reference line which is supposed to show the average across the entire time-frame is showing 50.8%, the simple average (i.e. [100+24.2+28.3]/3) instead of the weighted average (i.e. [100*2+641*24.2+1004*28.3]/[2+641+1004]).
In the rows shelf, I have a measure called "% that meet the criterion", this is defined as SUM([Criterion])/SUM([NUMBER OF RECORDS])
The criterion measure is 1 for any record that qualifies and null for any that do not qualify.
If I go to Analysis >> Totals >> Show Row Grand Totals, a 4th bar is added, and that bar shows the correct weighted average of the other three bars (26.8%), but I really want this to be shown as a reference line instead of having an extra bar on the chart. (Adding the Grand Total bar also drops the reference line down to 44.8%, which is the simple average of the 4 bars now shown on the chart--I can't think of a less useful piece of information than that).
How can I add the weighted average as a reference line?
Instead of using 'Average' as your aggregation, try using 'Total' instead in the Edit Reference Line dialogue window.
I have to say it's a bit counter-intuitive, but this is what the Tableau online help has to say about it:
http://onlinehelp.tableau.com/current/pro/online/mac/en-us/reflines_addlines.html
Total - places a line at the aggregate of all the values in either the cell, pane, or the entire view. This option is particularly useful when computing a weighted average rather than an average of averages. It is also useful when working with a calculation with a custom aggregation. The total is computed using the underlying data and behaves the same as selecting one of the totals option the Analysis menu.
If you are using Tableau 9, you can make second calculated field using an LOD expression
{ SUM([Criterion]) / SUM([NUMBER OF RECORDS]) }
This will calculate the ratio for the entire data set after applying context and data source filters, without partitioning the data by any of the other dimensions in your view (such as month in your case)
If you place that new field on the detail shelf then you can use it to create a reference line.
There are other ways to generate a weighted average, but this is probably the simplest in your case.
I need to create a report where each page contains four columns. I initialy had them as subreports but I guess they dont need to be.
How do I make it so each entry in a supplied dataset is represented as a column? Say if I had a dataset with 6 rows, the report would span two pages with four columns on the first and two on the second.
In other horizontal reports I had one dataset row represented as a row in the detail section of the report. But now I need four dataset set rows for each detail section, as the detail section contains four columns.
Guess what I really am looking for is a vertical detail section, sort of, while retaining the rest of the report horizontal.
I suggest using a Crosstab - these are the Crystal equivalent of pivot tables in Excel, or matrixes in SSRS.
