I am trying to use Tableau's row total function but am running into a challenge. In the same widget I have Rows 1 - 4 with Numbers. Row 5 is a percentage.
What I would like to do is have Rows 1 - 4 use a Sum Total and Row 5 use an Average total.
Any suggestions on how I can do this?
Thanks,
I don't believe you can use different total metrics on the same worksheet.
What you can do is to create 2 different worsheets, and bring them side by side on a dashboard. Then use the proper Total metric in each.
But beware on calculation average of percentages, because they might be twisted. Usually weighted average is required to accurately express the "average" of a percentage.
What you can do is to actually calculate the percentage (use a calculated field) via the division of two metrics. That way, when you do Totals you will actually a valid value for the "average" of the percentage.
As an exercise, suppose you have sales (in $) in first row, and # of clients in row 2. Now I create a calculated field called ticket, that is
SUM(sales) / sum([# of clients])
That way I can add that to a third row, and for each column I'll have the right number of ticket, and if I add a Row Grand Total, I'll get the actual average ticket value (that is total sales / total # clients), because Tableau will sum all sales, sum all # clients and them perform the calculation (the division)

I want to create a graph which shows the total capacity for each week relative to remaining availability across a series of specific dates. Just now when I attempt this in Power Bi it calculates this correctly for one of the values (remaining availability) but generates a value much higher than expected by manual calculation for the total capacity - instead showing the total for the entire column rather than for each specific date.
Why is Power Bi doing this and how can I solve it?
So far, I have tried generating the graph like this:
(https://i.stack.imgur.com/GV3vk.png)
and as you can see the capacity values are incredibly high they should be 25 days.
The total availability values are correct (ranging from 0 to 5.5 days).
When I create matrices to see the sum breakdown they are correct but it only appears to be that when combined together one of the values changes to the value for the whole column.
If anyone could help me with this issue that would be great! Thanks!
I am using RANK function in Tableau and I am displaying the Rank of calculated measure (Eg: 1 to 50)
The calculated Measure I have is Total Amount for Combined Periods.
When there is no Period displayed on the dashboard, the Total Amount is the sum of both periods and this is exactly what I want. I am good in this case.
However, When I want to display the Period in the Rows, the Total Amount changes to "Total Amount for Period 1 and Total Amount for Period 2".
How can I add a different axis to show Individual Periods as well as Rank of Total Amount for Combined Period?
I guess this might come down to Dual axis in Tableau and I believe this is not available yet and users are voting for this in Ideas.
I calculate the percent of total number of active customers for each SalesOwner in one of my Workbook sheets:
As you see, I have also added the SalesOwner as a filter.
The calculated field (segment_active_members) is computed using the following formula:
COUNTD(wk_customer)/ SUM({FIXED : COUNTD([wk_customer])})
What I want to do is create a side-by-side bar chart where upon filtering one of SalesOwners, I am able to compare it with the total (100%). So if I filter the above sheet by SalesOwner X which takes 5% of total. I'd like to see only two bars with one having 5% of the other one's length.
So I add another calculated filed to the above scenario where a fixed total is calculated:
SUM({FIXED : COUNTD([wk_customer])}
We will have a new column in the above picture with a fixed value of 100% for all rows.
I get what I want when my filter is on "All".
But as soon as I select a single filter (SalesOwner), my first percentage is also changed into 100% and I can never compare it to total.
How can I show the percentage against total for single segments?
This could be one of the solution:
Change the calculation of segment_active_members as follows
SUM({FIXED [Sales Owner]: COUNTD([wk_customer])})/SUM({COUNTD([wk_customer])})
Remove the table calculation for segment_active_members in the Measure Values shelf
You'll see that you are able to filter it down without any problem now
Cheers!
I need to calculate the average of multiple averages within Crystal Reports with specific criteria. My report averages scores for multiple courses by a developer. I need to get the average value of the averages, based on the number of courses for that developer:
Course 1 10 responses Course 1 Average 42.86
Course 2 12 responses Course 2 Average 39.36
How do I create a formula that give me the correct Average ((42.86 + 39.36)/2) of those two courses for that developer?
Try a Running Total for that field, where the Type of Summary is set to "Average". Specify that the total should reset every time it reaches a new Developer group.
Sometimes Crystal won't let you summarize a summary. If it gives you guff, you can achieve the same effect with Shared Variables. Simply add each average in turn to the shared variable, then divide by a distinct count of averages. The final Formula field would look something like:
Shared NumberVar sum;
Shared NumberVar count;
sum/count
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.
