Something that in excel would be pretty easy but i can't figure out how to translate something like this into Spotfire. That exact expression won't work becuase the resulting values are inconsistent: some are strings like "Q1" and 0 is an integer.
To resolve you would need to make your 0 a string by wrapping it in quotes, like:. You can use nested If functions but it is very inefficient and confusing.
It is better to use a case statement in situations like this:. This Question already has a 'Best Answer'. If you believe this answer is better, you must first uncheck the current Best Answer.Combine and Link Multiple Datasets in Spotfire X - Join Data - Add Columns and Rows

Compensate for missing values required for Cross Table. Can I compare two values from different data tables? How to create new hierarchy column in data table by IronPython script? Haven't found what you are looking for? Ask a Question. Set Preferences SET.As you remember, we discussed a few IF formulas for numbers, dates and text values as well as how to write an IF statement for blank and non-blank cells. However, for powerful data analysis, you may often need to evaluate multiple conditions at a time, meaning you have to construct more sophisticated logical tests using multiple IF functions in one formula.
The formula examples that follow below will show you how to do this correctly. Suppose, you have a table with the results of two exam scores.
The first score, stored in column C, must be equal to or greater than The second score, listed in column D, must be equal to or exceed Only when both of the above conditions are met, a student passes the final exam. Easy, isn't it? Otherwise, the formula returns "Fail". The avoid this, you should use a nested IF function :. Column E will have the "Pass" mark if either the first score is equal to or greater than 20 OR the second score is equal to or greater than As you see in the screenshot below, our students have a better chance to pass the final exam with such conditions Scott being particularly unlucky failing by just 1 point :.
The formula might seem tricky, but in a moment, you will see that it is not! You just have to express two conditions as AND statements and enclose them in the OR function since you do not require both conditions to be met, either will suffice:.
The screenshot below indicates that we've got the formula right:. You can use as many logical functions as your business logic requires, provided that:.
These multiple IF functions are called nested IF functions and they may prove particularly useful if you want your formula to return 3 or more different results. For instance:.Cushman hawk
And now, let's write a nested IF function based on the above conditions. It's considered a good practice to start with the most important condition and make your functions as simple as possible.I am trying to create a calculated field based on multiple criteria and multiple columns.
The source data is from our Aspect ACD tables. I have attached an example of the results we are seeing in. The third column is what I am seeing using the failed Ad-Hoc Grouping. The last column highlighted in yellow is what I want to see. However, I am needing to write this same type of statement in Tableau, and am having difficulty figuring out how to do it. Any assistance in this would be most appreciated. Also, please let me know if I need to provide any additional information.
So the thing that's missing, it appears to me, is the IN operator. It looks like that SQL would translate to this unwieldy calc:. Thanks for the responses! I imagine that will be much easier to manage, as there at least applicaitons among all the call centers. Are there any constraints to the complexity of the IF statements?
For example, in Excelat leastthe limit is 7 nested IF statements The reason I ask about this, is that there are four Locations, and up to 8 call types per call center. For reference, I have begun testing this on my own, and have successfully added constraints for 14 of the above list. I'm still adding the other constraints, but it looks like this is going to work! Thanks Joe; that's better.
Fezzikjr - you might consider using a translation table in your database rather than writing this as a function. Then you just join in the translation table to get the answer. I'm trying to create 11 groups of percent ranges. I have the following nested if logic as a created field and it limits me to only 6 groups. I'm pretty sure there's no limits that way.
I didn't realise there was a limit on nesting IIF s though, either. I agree that Richard's suggestion that using an IF with a series of ELSEIF statements is the best solution for your question, but if anyone does run into an issue complexity limits, extracting the data allows you to get around the complexity limits of MS Jet. Samy AbdulSorry for re? To be fair, this re-resurrection's not all that bad a couple months. I will say that in In 10 years, I'm hoping that some of Tableau's query engine has evolved.
James Baker 's original solution was pretty straightforward as well, and was a completely valid suggestion.You can perform calculations on your data, and display the results as values in a new column that is added to the data table. In the expression used for the calculation, you can use an OVER statement.
How to use CASE Statements in Calculated Columns in Spotfire
However, using the OVER statement in calculated columns works differently from using it in custom expressions. In calculated columns, the OVER expression is used to calculate separate, fixed, values for different groups and the OVER expression might cause the data to be 'sliced into fewer records'. When you work with calculated columns, there are no axes available to navigate over, as in the case with custom expressions. Instead, you use the OVER expression to refer to a data column or hierarchy.
The calculated column with fewer records may not be very useful as a standalone column. However, let us add another column, where the previous expression is a part of the expression used:. This expression calculates each sales transaction's relative contribution to the total sales over the years within its fruit type.
In the bar chart below, the calculated column is selected on the Value axis using the Sum aggregation. In the expression used for calculating a column, you can use the OVER statement in combination with a node navigation method.
Note: Calculated columns are always calculated on all values in the column, no matter how you filter your data. That is, for each row, the total sum of sales for the fruit type in question is presented in the new column. The effect is slicing into fewer values and Note: The new column values will not change when data is filtered out afterwards. For example, if the data row at the top is filtered out, the calculated column values for the 'Apples' rows will still be Extended example The calculated column with fewer records may not be very useful as a standalone column.
Combining OVER with a node navigation method in a calculated column In the expression used for calculating a column, you can use the OVER statement in combination with a node navigation method.The OVER function is a very useful function in Spotfire that calculates expressions and aggregations across different groups of data. This post has additional examples using the OVER function, focusing on multiple columns and expressions requiring the Intersect function.
A common performance metric is the 90 Day IP. This is the average oil production during the first 90 days of production history. The next group to evaluate would include the rest of the wells in the North Field — those using Completion Type B:. We could get the same result without inserting a calculated column by using a Cross Table or Bar Chart or some other type of visualization as shown below. That leaves 2 groups of data that we want to compare Team and Seasonand each group has 2 unique values, for a total of 4 combinations.
We should end up with 4 unique values in our calculated column:. Thankfully Spotfire has a built-in function that does this for us. To calculate the average points per game to date, use the following expression:. So to calculate the average to date, Spotfire takes the average only when Season type regular or playoffs intersects with all previous seasons for a given row.Intervento del presidente sergio santoro
AllPrevious does include the current row in the calculation in our example above, the Avg PPG for the season. It gets a little trickier if we want to exclude this value from the calculation:. Another way to write that complex expression, since we already calculated Last Seasons Avg Points per Game to Dateis to just use the Previous function:.
This also demonstrates that sometimes its easier to do a calculation in 2 steps with 2 calculated columns, instead of 1 column with a complex expression. With this new column, Last Seasons Avg Points per Game to Datenow we can see for a given season whether his performance improved or not compared to the average of all previous seasons:.
His playoff performance compared to previous years is up and down over time. Can you please share that as well? Whoops, forgot to embed the data in Spotfire.
Thanks for pointing that out!! Just fixed it — you should be able to access that link again and get a new Zip folder with the updated Spotfire file with embedded data. I have a question. Can I know like how to put this in SPF. I am trying to calculate the 90 day IP for oil for oil production.Ms onedrive rest api
I would like to create a calculated column with a value for the maximum count of records with a certain category for each employee on any given day.
For example, if the category being reviewed is "dinner", we would like to know what is the maximum number of dinner transactions charged on any given day. But when trying to get the max count over days, I cant seem to get it to work. Here is the expression used:. This seems to provide the same answer as the first expression. Any idea on how to get this code to identify the value on the date with the most expenses for each employee? You may need to cast [Transaction Date] as a date if it is an actual DateTime.
Otherwise you'd get one for each unique DT. Learn more. Asked 2 years, 5 months ago. Active 1 year, 8 months ago. Viewed 2k times. I have a table of travel expenses for analysis. Do you have a date column? I would like to perform the calculation in the original table I understand that every record for that employee would have the same value, but that is the intention.
Yes, it is the [Transaction Date] value in the second expression. Active Oldest Votes. If i understand your question and comments correctly, you should be able to use intersect.The Arg1 expression is evaluated and when Arg1 is equal to Arg2 then Arg3 is returned. Arg1 is of type boolean, usually the result of a comparison.
Arg2 and Arg3 can be of any type, but must both be of the same type or null. The second and third argument only process subsets of the rows, which impacts all column-based and accumulating methods.
See below for more information. Used within an If- or Case- statement, to determine whether or not an expression yields an empty value null value. If [Column] Is Not Null, "value was not null", "value was null". If an expression contains empty values null valuesyou can use the SN function to substitute the null values with the specified value.
If [Column] Is Null, "value was null", "value was not null".
When you are using an If-statement in an expression, the condition in the first argument limits the values to be evaluated in the third argument. To understand how it works, first take a simple integer column as an example:.Ugc approved international journals with low publication fee
This will result in a new column with two different values; one for case when the max for all values that are smaller than 2 and one showing the max value for the rest of the values which also is the max of the entire column :.
The If-function is designed to split the column into two groups and then to continue evaluating the expression on the new groups. If you are using a Percentile expression instead, you will get different results on the same percentile expression depending on how the first condition has split the column:. As you can see, the value of the percentile will change depending on how 'If' has grouped the data.
When working with case expressions, the condition after "when" is calculated on the entire column. If multiple "when- then" pairs are included in the expression a "then" is limited by all previous conditions as well as the last one. Insert two calculated columns, called Case Min and Case Max, using the following expressions:. The case statement has two different forms. If Arg1,Arg2,Arg3. Is Not Null. Is Null.
