count the occurence of values in a column in tableau - tableau-desktop

I have a data set with 900 000 rows. There's a column "event_id". I want to create a table of occurences of event_id.
occured once = 63K
occured twice = 114K
occured thrice = 54k
and so on.
How can I do this in Tableau?

step_1 = drag event_id to rows
step_2 = drag filename.csv(count) to TEXT.

How to match a world with a list of items

I have a sheet that imports data, and I need to have a Colum that returns a different word based on what would be in Colum H. So if the sheets loads in, and it has "Green" in Colum H I want Colum AH to return a skill or queue.
EXAMPLE:
Colum H = Green then Colum AH = Queue1, Colum H = Red then Colum AH = Queue2 (I have about 20 queues) - This would just populate the queue name when the information loads in.
What this does is display "Queue1" whenever H has the word green in it if it's blank it just displaces "not found" I need to do this, but with a list of items. green = queue1, blue = queue 2, red = queue 3 etc all in one formula.
=IF(COUNTIF(H1565,"Green"),"Queue1", "Not Found")
try:
=INDEX(IFNA(VLOOKUP(A2:A10; D:E; 2; ); "Not Found"))

Google Spreadsheet dynamic conditional formatting with merged dropdown

How my sheet works
I'm making a spreadsheet to show how much parts I have. By using a dropdown, am I able to show that I created a product. With conditional formatting I am showing that having 0 items isn't an issue when the product is created. Created products with 0 items change from red to purple. Purple means it doesn't matter to have 0 items from this product.
My issue
My issue starts with my dropdown. If I merge cells, The value will go into the upperleft cell. This means other cells inside the merged cell are blank. This gives me a problem with conditional formatting.
My conditional formatting code example:
=if($D2=0;$E2="Created")
I have to change this code for every cell because of the condition combined with a dropdown. Having more than 250 rows would be inhumanly hard to do by hand.
My questions
Are there ways to give all cells of a merged cell the value of the combined cell in an efficient way?
Is there a better way to make my conditional formatting code applyable to merged cells?
This is my sheet
Product items collected sheet link (Shows the problem and solution!)
Product items collected sheet image (Version 1)
Product items collected sheet image (Version 2)
At the heart of this question is the operation of merged cells. When a cell is merged, say over several rows, only the cell at the top left of the merged cell can contain data, respond to conditional formatting, and so on. In a manner of speaking the other cells cease to exist and values CANNOT be assign to them.
The questioner asks:
Q: Are there ways to give all cells of a merged cell the value of the combined cell in an efficient way?
A: No. Not just in an "efficient" way; it's just not possible.
Q: Is there a better way to make my conditional formatting code applicable to merged cells?
A: No and yes ;)
No. In so far as a merged cell is concerned, everything is driven by the value in the top cell of the merged range. There are no other options for the "rest" of the merged cell.
Yes. I'd create a "helper" cells in Column F as in this screenshot
The code to achieve this is dynamic - it will automatically adapt to adding more products, more items, etc.
The logic is fairly simple: Start in F2, test whether E2 has a value (that is, is it the top of the merged cell?). If yes, then assign the value of E2 to F2 AND put that value in a variable for the following cells. If no, the cell in Column E must be part of a merged cell, so assign the value for Column F to the variable that was saved earlier.

UPDATE 22 October 2018
For development purposes, I used a small range of only 14 rows in Column E. However the questioner's data covers over 250 rows, so I expanded development testing to cover 336 rows (yeah, I know, but I was copy/pasting and I ended up with 336 and was too lazy to delete any rows. OK?). I found that the code took over 81 seconds to process. Not good.
The primary reason (about 80 seconds worth) for the long processing time is that there is a getValue statement within the loop - var ECellVal = ECell.getValue();. This costs about 0.2 seconds per instance. Including getValue in a loop is a classic performance mistake. My bad. So I modified the code to get the values of Column E BEFORE the loop
var Evals = sheet.getRange("e2:E").getValues();.
I was surprised when the execution time stayed around the same mark. The reason was that the isBlank evaluation - if (ECell.isBlank()) { which previously took no time at all, was now consuming #0.2 second per instance. Not good++. So after searching Stack Overflow, I modified this line as follows:
if (!Evals[(i-dataStart)][0]) {.
Including setValues in a loop is also asking for trouble. An option would have been to write the values to an array and then, after the loop, update the Column E values with the array. However in this case, the execution time doesn't seem to have suffered and I'm leaving the setValues inside the loop.
With these two changes, total execution time is now 1.158 seconds. That's a percentage reduction of , um, a LOT.

send email on a change in a cell value with message from another cell

I am new to google scripts. I have a range where the cells in a column change. If the number of a cell from that column is above zero then the script has to send an email with the message being the content from a cell in the same row with the updated cell(that is, different column) Let's say If a value in column I changes then automatically it has to send an email with the message contained in the same row but column F for example. Please see below, I would appreciate some help.
function SendValue() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Dividend");
var values = sheet.getRange("I2:I").getValues();
//var values1 = sheet.getRange("G2:G").getValues();
var results = [];
for(var i=0;i<values.length;i++){
if(values[i]>0){
results.push(sheet.getIndex([+i+2]+"G"));
// +2 because the loop start at zero and first line is the second one (I2)
}
}
MailApp.sendEmail('sxxxxxx#gmail.com', 'EX-DIVIDEND', results );
};
getValues() returns a 2 dimensional array, or more accurately an array of arrays, even if one of the dimensions is 1. values[i] is not a value but rather an array representing the i row of the range. You will need to acess that array to get at the cell at a particular column in that row.
replace if(values[i]>0) with if(values[i][0]>0)
I suspect that results.push(sheet.getIndex([+i+2]+"G")); should be results.push(sheet.getRange("G"+(i+2)).getValue()); as getIndex() doesn't take arguments and that looks like it is meant to be A1 notation.
However there is a better option than trying to construct A1Notation.
getRange() supports using numbers to refer to rows and columns. getRange(7, i+2) is a better choice.

Sum of specific elements in array

I have a couple of tableviewcells. It has 2 rate values 200 and 300 respectively. These 2 values I’m adding to an array like so
let theRateElement = (Int(product?.theRate ?? "") ?? 0)
rateArray.append(theRateElement)
self.sumedArr = rateArray.reduce(0, { ($0 + $1)})
Now, my summedArr will have the value 500
I also have on my tableviewcell a picker textfield. The picker gives values from 1 to 10. If I select 2 from the pickerview of first cell, then that 2 will be multiplied with 200 to give 400 & if I select 3 from the pickerview of 2nd tableview cell, then then the value of 300 will become 900 (300*3)
I'm taking the sum of these 2 new values like so...(in picker didSelectRow)
let finalAmt = fixedRate * totalItems
let theRateElement = finalAmt
updatedRateArray.append(theRateElement)
self.sumedArr = updatedRateArray.reduce(0, { ($0 + $1)})
Now summedArr will have the value (200*2)+(300*3) = 1300
But what I want to achieve is if I multiply just the 1st value of 200 by 2 to get 400 and keep the 2nd value of 300 as it is then I should get the total as 400+300 = 700. But how to achieve this that I’m not able to figure out.
The issue could be fixed like so...
There is an array which has the initial values of 200 & 300. Now the value with which I will multiply 2, 3 etc. is surely one of the values of the initial array. So that is checked and those values are removed. Now the initial array will be left with those elements which is not multiplied by any number.
The nos. which are multiplied is also stored in an array. Now this array and the initial array are both combined and their elements are added. This finally gives me the sum of numbers multiplied by 2,3,4...etc. and those numbers which are not multiplied which is the desired result..
