Im trying to show the total number of people in each geography when they hover over using crossfilter, but my current code is only showing the total of all geographies. So what is the equivalent in crossfilter to the sql query: SELECT COUNT(*) GROUP BY dma
This is my code so far
//geography that is being hovered over, getting dma name and removing everything that is after the comma
sel_geog = layer.feature.properties.dma_1;
sel_geog = sel_geog.split(",")[0];
console.log(sel_geog);
//crossfilter to get total number of people of each geography
var dmaDim = voter_data.dimension(function(d) {return d.dma == sel_geog}),
dma_grp = dmaDim.groupAll().reduceCount().value();
console.log(dma_grp);
Crossfilter isn't meant to be used in a way where you are building new dimensions and groups for each user interaction. It's meant to build dimensions and groups before interactions take place and then update them quickly when filtering based on user interactions.
It's not really clear from this question what your data looks like or what you are trying to do, but you probably want to create dimensions and group for your dma property and then build your map based on that:
var voter_data = crossfilter(my_data);
var dmaDim = voter_data.dimension(function(d) { return d.dma; });
var dmaGroup = dmaDim.group();
At this point dmaGroup.all() will be an array of objects that looks like { key: 'dmaKey', value: 10 } where 10 is the count of all records where d.dma === 'dmaKey'. There are lots of ways you can aggregate differently with Crossfilter, but that may get you started.

I have two datasets:
Dataset 1 - Records the details of a store visit. Merchandiser name, location, date & a relation to SKU (Dataset 2)
Dataset 2 - This is the SKU data, where the stock levels for each sku are input as a new record, each associated to a visit from Dataset 1.
I have two issues:
I want to combine this data into a single table. I want to show each SKU record, with additional columns for the visit information (such as the location & date). How do I do this.
How do I combine this data for use elsewhere, such as google data studio. Essentially I want to be able to see an SKU's stock-level's history, or the date it was last updated.
You need to create Calculated Data Source. You can refer this sample.
On a high Level
Add data source in Appmaker.
Select Calculated, provide Name and Create the data source.
Once your Calculated Model is in place. Add fields as per need basis. e.g. If you want to store Sum of two fields, create one Integer field in Calculated Model. Here's how your calculated data model will look like.
Now go to Second Tab which is "Datasources". Click on the Data Model name there. You should see an option to write server side script.
Here you should write your logic for combining your data sources. I can provide you one sample to achieve this.
//server script
var calculatedModelRecords = [];
var recordsByStatus = {};
var allRecord = app.models.Request.newQuery().run(); //your existing data source.
for (var i = 0; i < allRecord.length; i++) {
var record = allRecord[i];
var draftRecord = app.models.TAT.newRecord(); //new data source
draftRecord.CreatedOn = record.CreatedOn;
draftRecord.DocumentName = record.DocumentName;
draftRecord.DueDate = record.DueDate;
draftRecord.DaysPerStage = record.DaysPerStage;
draftRecord.Status = record.Status;
calculatedModelRecords.push(draftRecord);
}
return calculatedModelRecords;
this might look simple.. but dk how to do it
this is the information:
So.. i got the Cumulative Total using this function:
CumulativeTotal = CALCULATE(
SUM(vnxcritical[Used Space GB]),
FILTER(ALL(Datesonly[Date]),
Datesonly[Date] <= MAX(Datesonly[Date])))
But what i need is to get the differences between the dates, in the first date and the second the difference will be of 210. I need to get another column with that information. know the formula to do that?
ok..
So.. i used this:
IncrmentalValueTEST =
VAR CurrDate = MAX(vnxcritical[Date])
VAR PrevDate = CALCULATE(LASTDATE(vnxcritical[Date]), vnxcritical[Date] < CurrDate)
RETURN SUM(vnxcritical[Used Space GB]) -
CALCULATE(SUM(vnxcritical[Used Space GB]), vnxcritical[Date] = PrevDate)
and this is the result:
Ok, so this is is my data table:
You can see all the dates that i have for now, this is a capacity report for diferents EMC Storage Arrays, for diferentes Pools. The idea would be to have the knolwdge to review the incremental space used in a determinated portion of time.
allready tried another idea to get this, but the result was the same.. i used this:
Diferencia =
Var Day = MAX(Datesonly[Month])
Var Month = MAX(Datesonly[Year])
RETURN
SUM('Used Space'[used_mb])
- CALCULATE(
SUM('Used Space'[used_mb])
,FILTER(ALL(Datesonly[Date]),Datesonly[Date] <= Max(Datesonly[Date])))
But the return is the same.. "47753152401"
i'm using graphical filters, and other things to get a minimal view, because there are only 5 weekly reports and the sql database got more than 150.000 rows.
and this is the relation that i made with a only a table full of "dates" in order to invoke the function in a better way, but the result is the same..
Try something along these lines:
IncrmentalValue =
VAR CurrDate = MAX(Datesonly[Date])
VAR PrevDate = CALCULATE(LASTDATE(Datesonly[Date]), Datesonly[Date] < CurrDate)
RETURN SUM(vnxcritical[Used Space GB]) -
CALCULATE(SUM(vnxcritical[Used Space GB]), Datesonly[Date] = PrevDate)
First, calculate the current date and then find the previous date by taking the last date that occurred before it. Then take the difference between the current value and the previous value.
In icCube reporting tool 6.1
is there a possibility to retrieve data like a cellValue(rowindex,columnindex) while i'm in a diffrent widget like chart box for example and wanna get a cell value from different table in the report? with Widget's JavaScript...? and also do other functions like column count or row count as i'm in the Widget's JavaScript of the actual table...?
UPDATED QUESTION
Example:
i wanna be able for example to get in the chart palette by Expression to
retrieve the number of the 1 row and column 2 (value 12)
and then for the example i wanna use this number and see if the number is greater then 10 then i will want the chart color to be Green and if less the blue... so i wanna know how to retrieve a specific cell from the table when the chart loads... and the chart will wait for a click on row from the table
so it will load after the table... so the rendering problem you've mentioned you have won't be a problem here.
You can share Table's data with global variable.
In On Data Received hook:
/**
* Return data object
*/
function(context, data, $box) {
window.ic3Data = {};
window.ic3Data.tableContext = context;
return data;
}
Then you can easily use PublicTableContext API from table widget in other charts. For example in a coloring expression for an AmChart:
return window.ic3Data.tableContext.cellValue(0,1) > 10 ? 'green' : 'red';
I've been searching for similar solutions out there but am coming up short so far. Here is what I want to accomplish:
I need to come up with a basic solution to sync inventory quantities at the end of each day. We take physical counts of inventory sold throughout the day but need something to log these changes and share between users. I would like to utilize two buttons (click one to subtract amount of items sold at the end of the day and click one button to add newly received inventory).
This is how my sheet is set up:
Col A: Product Tag
Col B: Product sku
Col C: Amount Sold Today
Col D: Total Inventory Quantity
Col E: Add New Inventory
Column D will be pre-populated with initial inventory counts. At the end of each day, I would like to go down my product list and fill in the amount of each item sold that day in Column C. Once Column C is fully populated, I would like to click the "subtract" button and have Column C subtracted from Column D.
On the other side, once we receive new stock of an item I would like to enter these counts into Column E. Once this column is fully populated, I would like to click the "Add" button and have Column E added to Column D. Ideally once the add or subtract function has been completed, columns C or E will be cleared and ready for the next days entry.
I already have designed my buttons, I just need help coming up with the scripts to accomplish this.
You can use Google Apps Script for this.
If you are unfamiliar, in your particular spreadsheet, go to Tools → Script Editor and then select the Blank Project option.
Then you can write functions like this to achieve what you want!
function subtractSold() {
var sheet = SpreadsheetApp.getActiveSheet();
var c1 = sheet.getRange("C2");
var c2 = sheet.getRange("D2");
while (!c1.isBlank() && !c2.isBlank()){
c2.setValue(c2.getValue() - c1.getValue());
c1.clear();
c1 = c1.offset(1, 0);
c2 = c2.offset(1, 0);
}
}
Basically what the function does is:
Get a reference to the active spreadsheet
Get references to the cells C2 and D2, for the first row of data.
Use a while loop to repeated go through the rows. Terminate when either cell is empty.
In the loop, we get the appropriate values, subtract and set the value back into the cell. Then we clear the cell in column C. We then move both cell references down by one row (the offset method returns a reference to the original cell, but offset by row, column).
Then assign the script to the button image by entering the name of the function (subtractSold in this case) in the "Assign script" option for the button.
I have made an example sheet here (go to File → Make a Copy to try the scripts and see the code): https://docs.google.com/spreadsheets/d/1qIJdTvG0d7ttWAUEov23HY5aLhq5wgv9Tdzk531yhfU/edit?usp=sharing
A bit faster
If you try the sheet above you can see it processes one row at a time, which might get pretty slow when you have a lot of rows. It is probably faster to process the entire column in bulk, but it may be a bit more complicated to understand:
function subtractSoldBulk() {
var sheet = SpreadsheetApp.getActiveSheet();
var maxRows = sheet.getMaxRows();
var soldRange = sheet.getRange(2, 3, maxRows); // row, column, number of rows
var totalRange = sheet.getRange(2, 4, maxRows);
var soldValues = soldRange.getValues();
var totalValues = totalRange.getValues();
for (var row in soldValues) {
var soldCellData = soldValues[row][0];
var totalCellData = totalValues[row][0];
if (soldCellData != "" && totalCellData != "") {
totalValues[row][0] = totalCellData - soldCellData;
soldValues[row][0] = "";
}
}
soldRange.setValues(soldValues);
totalRange.setValues(totalValues);
}
The difference here is that instead of getting one cell, we get one range of cells. The getValues() method then gives us a 2D array of the data in that range. We do the calculations on the two arrays, update the data in the arrays, and then set the values of the ranges based on the array data.
You can find documentation for the methods used above from Google's documentation: https://developers.google.com/apps-script/reference/spreadsheet/sheet
I'm creating a table that displays information from a MySQL database, I'm using foreignkeys all over the place to cross-reference data.
Basically I have a datagrid with a column named 'system.' The system is an int that represents the id of an object in another table. I've used lableFunction to cross-reference the two and rename the column. But now sorting doesn't work, I understand that you have to create a custom sorting function. I have tried cross-referencing the two tables again, but that takes ~30sec to sort 1200 rows. Now I'm just clueless as to what I should try next.
Is there any way to access the columns field label inside the sort function?
public function order(a:Object,b:Object):int
{
var v1:String = a.sys;
var v2:String = b.sys;
if ( v1 < v2 ){
trace(-1);
return -1;
}else if ( v1 > v2 ){
trace(1);
return 1;
}else {
trace(0);
return 0;
}
}
One way to handle this is to go through the objects you received and add the label as a property on each of them based on the cross-referenced id. Then you can specify your label property to display in your data grid column instead of using a label function. That way you would get sorting as you'd expect rather than having to create your own sort function.
The way that DataGrids, and other list based classes work is by using itemRenderers. Renderers are only created for the data that is shown on screen. In most cases there is a lot more data in your dataProvider than what is seen on screen.
Trying to sort your data based on something displayed by the dataGrid will most likely not give you the results you want.
But, there is no reason you can't call the same label function on your data objects in the sortFunction.
One way is to use the itemToLabel function of the dataGrid:
var v1:String = dataGrid.itemToLabel(a);
var v2:String = dataGrid.itemToLabel(b);
A second way is to just call the labelFunction explicitly:
var v1:String = labelFunction(a);
var v2:String = = labelFunction(b);
In my experience I have found sorting to be extremely quick, however you're recordset is slightly larger than what I usually load in memory at a single time.
