I have a data set similar to the table below (simplified for brevity)
I need to calculate the total spend per conversion per team for every month, with ability to plot this as time based line chart being an additional nicety. The total spend is equal to the sum of Phone Expenditure, Travel allowance & Misc. Allowance, this can be a calculated field.
I cannot add a calculated field for the ratio, as for some sales person, the number of conversion can be 0 for a given month. So, averaging over team is not option. How can I go about this?
Thanks for help and suggestions in advance!
I've discussed the question with the Harish offline. I've learned that he is trying to calculate ratio per group, not per row.
To perform calculations per group, users can add calculated fields inside a QuickSight analysis and use level aware aggregation expressions. (Note that level aware aggregations can only be used in an analysis, not in the data prep view). Here is a link to the documentation about level aware aggregations if you want to learn more about this area https://docs.aws.amazon.com/quicksight/latest/user/level-aware-aggregations.html

I usually do it in Excel but it is not easy for me to do it in KIBANA as well
I have this table in Excel and every hour I want to average for all instancs in the fiels "detail" but excluding the lowest three values (nine details each hour, the average should be only for the the six highest of them). In Excel I use the LARGE function.
https://docs.google.com/spreadsheets/d/1LcKO8TGl49dz6usWNwxRx0oVgQb9s_h1/edit?usp=sharing&ouid=114168049607741321864&rtpof=true&sd=true
In your opinion is there any chance to do it directly in KIBANA?
No idea how to proceed
You can use lens table visualization and set the number of rows to 6 and order rows by descending order of your CPU load. Look at the sample data table here
The average here is calculated for the top 6 values of bytes only.
Here are the settings:
You can try replacing the clientIP here by details and bytes by CPU load
No, it is not possible to automatically remove the last N results from the equation in Kibana. You should be manually filtering out from the list in the visualization every time.
The only alternative I see is to add an extra step that deletes or flags the 3 results per hour you want to exclude, and then in Kibana you just add a regular filter.
The easiest way I can think of is creating a watcher that groups the results by hour, sort by CPU, and then ingest the first 6 results in a different index you can query using Kibana.
Docs: https://www.elastic.co/guide/en/elasticsearch/reference/current/xpack-alerting.html
If this acceptable for you I can edit this answer with more details about the Watcher I would create.
whenever I use the periodOverPeriodPercentDifference in the quicksight pivot table, it only gives the values for the lowest granularity on the row-wise basis and if I collapse all then all I can see is a blank in that calculated field. Is there any alternative for the periodOverPeriodPercentDifference in quicksight?
I tried with periodOverPeriodPercentDifference it's but no use so I want an alternative for that. can anyone help me with that?
short description:
Calculates Percent difference of the measure over two different time periods as specified by Period Granularity (** defaults to visual aggregation granularity **) and Offset (defaults to 1).
I'm facing a following problem. In Kibana 4 I've created a line chart based on my input from elasticeasrch but I can only display average, min, max instead of an actual value of the field per time, e.g. sent bytes.
Most answears to that question on stackoverflow are about Kibana 3 (How to create value over time chart with Kibana 3?) and seem to include a Histogram on a X axis, yet I can't seem to find one which will enable me to apply them to Kibana 4. I was unable to find the histogram panel and once I click on the discover tab there is the constant Searching loading.
If I have the following fields in my _source:
{"timestamp":"2015-06-02T10:16:44.0855","time":587,"threadName":"Thread Group 1-957","byte":1372,"status":"false","latence":306,"registerCall":"404"}
and I would like to have the number of bytes on the Y-axis and on the X-axis my timestamp.
Any help in the right direction will be appreciated :)
To create a value over time line chart in Kibana, follow these steps:
Go to visualize tab and select line chart
In the X-axis, select X-axis, Aggregation as Date Histogram and then select your timestamp field as the date field.
Next for the Y-Axis, select Sum as the aggregation and then bytes as the field.
For the X axis, what Alcanzar said is good, but as you notice, the Y axis is problematic.
Sum (suggested by "Limit") works, but since it's aggregated, it shows the total used in each aggregated bucket, but that may be meaningless depending on what you are trying to show. Your question isn't clear on what you want, so I'm just guessing here. One hour of requests, each of which ran for one minute and sent 1 megabyte is indeed 60 megabytes-minutes, if you are trying to show total capacity used over than hour (maybe you are paying a bill based on usage per time). On the other hand, if you are trying to show peak usage in each time, it would be wrong.
You said you already looked and Max and Min and they don't meet your needs. I don't suppose Standard Deviation would be any better?
I have the same concern. The best I've been able to do so far is
display Min and Max simultaneously in the Y axis. When they diverge, I know I'm zoomed out too far, so I zoom in until they align.
This is how I know I'm seeing individual events.
In any case, I share your frustration. I too would like to be able to show time series as easily as I can in, say, Excel.
I am building a finance cube and trying to understand the best practice while designing my main fact table.
What do you think will be a better solution:
Have one column in the fact (amount) and have an additional field which will indicate the type of financial transaction (costs, income, tax, refund, etc).
T
TransType Amount Date
Costs 10 Aug-1
Income 15 Aug-1
Refunds 5 Aug-2
Costs 5 Aug-2
"Pivot" the table to create several columns according to the type of the transaction.
Costs Income Refund Date
10 15 NULL Aug-1
5 NULL 5 Aug-2
Of course, the cube will follow whatever option is selected - several real measures vs several calculated measures which each one of the are based on one main measure while being sliced on a member from a "Transaction Type" dimension.
(in general all transaction types has the same number of rows)
thank you in advanced.

For a finance related cube, I believe it is much better to use account dimension functionality.
By using account dimension, you can add/remove accounts to the dimension without changing the structure of your model. Also if you use account dimension, time balance(aggregate function) functionality of the cube cube can help you a lot.
However SSAS account dimension has its own problems as well. For example, if you assign time balance to a formula or a hierachical parent, it is silently ignored and that is not documented as far as I know. So be ready to fix the calculations in the calculation script.
You can also use custom rollup member functionality to load your financial formulas.
In our case, we have 6000+ accounts, and the formulas can change without our control.
So having custom rollup member functionality helps a lot.
You need to be careful with solve orders(ratios..) etc, but that is as usual for any complicated/financial cube.
Tableau:
This may seem simple, but I ran out of the usual tricks I've used in other systems.
I want a variance column. Essentially adding a member 'Variance' to the Act/Plan dimension which only contains the members 'Actual' and 'Plan'
I've come in where the data structure and reporting is set up like so:
Actual | Plan
Profit measure
measure 2
measure 3
etc
The goal is to have a Variance column (calculated and not part of the Actual/Plan dimension)
Actual | Plan | Variance
Profit measure
measure 2
measure 3
etc
There are solutions where it works for one measure only, and I've looked into that.
ie, create calculated field as such
Profit_Actual | Profit_Plan | Variance
You put this on the columns, and you get a grid that I want... except a grid with only 1 measure.
This does not work if I want to run several measures on rows. Essentially the solution above will only display the Profit measure, not Measure 1_Actual , Measure 2_Plan etc.
So I tried a trick where I grouped a the 3 calculated measures, ie Profit_Actual | Profit_Plan | Profit_Variance as 'Profit_Measure'
Created a parameter list - 'Actual', 'Plan', 'Variance'
Now I can half achieve my goal, by having the parameter on columns and the 'Profit Measure' on Rows (so I can have Measure 123_group etc down on rows too). Trouble is, I found that parameters are single select only. Only if it can display all options in the custom paramater at once, I would've solved my problem.
Any ideas on how I can achieve the Variance column I want?

Okay. First thing, I had a really hard time trying to understand how your data is organized, try to be more clear (say how each entry in your database looks like, and not how a specific view in Tableau looks like).
But I think I got it. I guess you have a collection of entries, and each entry has a number of measure fields (profits and etc.) and an Act/Plan field, to identify whether that entry is an actual value or a planned value. Is that correct?
Well, if that's the case, I'm sorry to say you have to calculate a variance field for each dimension. Think about it, how your original dataset is structured. Do you think you can add a single field "Variance" to represent the variance of each measure? Well, you can, store the values in a string, and then collect it back using some string functions, but it's not very practical. The problem is that each entry have many measures, if it had only 1 measure, than 1 single variance field would suffice.
So, if you can re-organize your data, what would be an easier to work set (but with many more entries) is something with the fields: Measure, Value, Actual/Plan. The measure field would have a string to identify what you're measuring in that entry. Value would be a number to represent the actual measure. And the Actual/Plan is the same. For instance:
Measure Value Actual/Plan
Profit 100 Actual
So, each line in your current model would become n entries, where n is the number of measures you have right now. So a larger dataset in a way, but easier to work with. Think about, now you can have a calculated field, and use some table calculations to calculate the variance only for that measure and/or Actual/Plan. Just use WINDOW_VAR, and put Measure and/or Actual/Plan in the partition.
Table calculations are awesome, take a look at this to understand it better. http://onlinehelp.tableausoftware.com/current/pro/online/en-us/help.htm#calculations_tablecalculations_understanding_addressing.html
I generally like to have my data staged such that Actual is its own column and Plan is its own column in the data being fed to Tableau. It makes calculations so much easier.
If your data is such that there is a column called "Actual/Plan" and every row is populated with either "Actual" or "Plan" and there is another column called "Value" or "Measure" that is populated with the values, you can force Tableau to make them columns assuming you can't or won't rearrange your data.
Create a calculated field called "Actual" with the following calc:
IF [Actual/Plan] = 'Actual' THEN [Value] END
Similarly, create a calculated field called "Plan" with the following calc:
IF [Actual/Plan] = 'Plan' THEN [Value] END
Now, you can finally create your "Variance" and "Variance %" calculations (respectively):
SUM([Actual]) - SUM([Plan])
[Variance] / SUM([Plan])
