Here is piece of code which is applied after grouping is done and the GroupingCollection is assigned to the grid.
//Sorting grid once grouping done
dataGrid.validateNow();
var s:Sort = new Sort();
s.fields = [new SortField("hazardnum")];
s.compareFunction = hazardSortItems;
dataGrid.dataProvider.sort=s;
dataGrid.dataProvider.refresh();
Here is my compare function,
private function hazardSortItems(a:Object, b:Object,fields:Array=null):int {
return ObjectUtil.stringCompare(a.hazardnum.toString(),b.hazardnum.toString(),false);
}

Split a list into groups of consecutive elements based on a condition in Kotlin
(4 answers)
Closed 7 months ago.
I want to groupBy a list of items by its value, but only if subsequent, and ignore grouping otherwise:
input:
val values = listOf("Apple", "Apple", "Grape", "Grape", "Apple", "Cherry", "Cherry", "Grape")
output: {"Apple"=2, "Grape"=2, "Apple"=1, "Cherry"=2, "Grape"=1}
There's no built in option for this in Kotlin - it has to be custom, so there are many different options.
Because you need to keep track of the previous element, to compare the current one against, you need to have some sort of state. To achieve this you could use zipWithNext or windowed to group elements. Or use fold and accumulate the values into a list - removing and adding the last element depending on whether there's a break in the sequence.
To try and keep things a bit more clearer (even if it breaks the norms a bit) I recommend using vars and a single loop. I used the buildList { } DSL, which creates a clear scope for the operation.
val result: List<Pair<String, Int>> = buildList {
var previousElement: String? = null
var currentCount: Int = 0
// iterate over each incoming value
values.forEach { currentElement: String ->
// currentElement is new - so increment the count
currentCount++
// if we have a break in the sequence...
if (currentElement != previousElement) {
// then add the current element and count to our output
add(currentElement to currentCount)
// reset the count
currentCount = 0
}
// end this iteration - update 'previous'
previousElement = currentElement
}
}
Note that result will match the order of your initial list.
You cloud use MultiValueMap which can has duplicated keys. Since there is no native model you should implement yourself or use the open-source library.
Here is a reference.
Map implementation with duplicate keys
For comparison purposes, here's a short but inefficient solution written in the functional style using fold():
fun <E> List<E>.mergeConsecutive(): List<Pair<E, Int>>
= fold(listOf()) { acc, e ->
if (acc.isNotEmpty() && acc.last().first == e) {
val currentTotal = acc.last().second
acc.dropLast(1) + (e to currentTotal + 1)
} else
acc + (e to 1)
}
The accumulator builds up the list of pairs, incrementing its last entry when we get a duplicate, or appending a new entry when there's a different item. (You could make it slightly shorter by replacing the currentTotal with a call to let(), but that would be even harder to read.)
It uses immutable Lists and Pairs, and so has to create a load of temporary ones as it goes — which makes this pretty inefficient (𝒪(𝑛²)), and I wouldn't recommend it for production code. But hopefully it's instructive.
I am trying to add columnSummary to my table using Handsontable. But it seems that the function does not fire. The stretchH value gets set and is set properly. But it does not react to the columnSummary option:
this.$refs.hot.hotInstance.updateSettings({stretchH: 'all',columnSummary: [
{
destinationRow: 0,
destinationColumn: 2,
reversedRowCoords: true,
type: 'custom',
customFunction: function(endpoint) {
console.log("TEST");
}
}]
}, false);
I have also tried with type:'sum' without any luck.
Thanks for all help and guidance!
columnSummary cannot be changed with updateSettings: GH #3597
You can set columnSummary settings at the initialization of Handsontable.
One workaround would be to somehow manage your own column summary, since Handsontable one could give you some headeache. So you may try to add one additional row to put your arithmetic in, but it is messy (it needs fixed rows number and does not work with filtering and sorting operations. Still, it could work well under some circumstances.
In my humble opinion though, a summary column has to be fully functionnal. We then need to set our summary row out of the table data. What comes to mind is to take the above mentioned additional row and take it away from the table data "area" but it would force us to make that out of the table row always looks like it still was in the table.
So I thought that instead of having a new line we could just have to add our column summary within column header:
Here is a working JSFiddle example.
Once the Handsontable table is rendered, we need to iterate through the columns and set our column summary right in the table cell HTML content:
for(var i=0;i<tableConfig.columns.length;i++) {
var columnHeader = document.querySelectorAll('.ht_clone_top th')[i];
if(columnHeader) { // Just to be sure column header exists
var summaryColumnHeader = document.createElement('div');
summaryColumnHeader.className = 'custom-column-summary';
columnHeader.appendChild( summaryColumnHeader );
}
}
Now that our placeholders are set, we have to update them with some arithmetic results:
var printedData = hotInstance.getData();
for(var i=0;i<tableConfig.columns.length;i++) {
var summaryColumnHeader = document.querySelectorAll('.ht_clone_top th')[i].querySelector('.custom-column-summary'); // Get back our column summary for each column
if(summaryColumnHeader) {
var res = 0;
printedData.forEach(function(row) { res += row[i] }); // Count all data that are stored under that column
summaryColumnHeader.innerText = '= '+ res;
}
}
This piece of code function may be called anytime it should be:
var hotInstance = new Handsontable(/* ... */);
setMySummaryHeaderCalc(); // When Handsontable table is printed
Handsontable.hooks.add('afterFilter', function(conditionsStack) { // When Handsontable table is filtered
setMySummaryHeaderCalc();
}, hotInstance);
Feel free to comment, I could improve my answer.
I've got a system that generates and automatically maintains lots of spreadsheets on a Drive account.
Whenever I add data to the sheet I run a 'format' method to pass over and make sure everything is ok.
This generally does things like:
set the default font and size across the sheet
set up the heading row
freeze rows
In addition, I have the code below to make sure the first two columns (index 0 and 1) in the sheet are autoresizing to fit their contents. when I run it though, this element doesn't seem to make a difference. The font, column freezes etc all work.
Other notes:
I only want those 2 columns to auto-resize
the amount of rows in a sheet can vary
this job is appended to the end of several in requestList
My code:
requestList.Requests.Add(new Google.Apis.Sheets.v4.Data.Request()
{
AutoResizeDimensions = new AutoResizeDimensionsRequest()
{
Dimensions = new DimensionRange()
{
SheetId = Convert.ToInt32(sheetId),
Dimension = "COLUMNS",
StartIndex = 0,
EndIndex = 1
}
}
});
var updateRequest = sheetService.Spreadsheets.BatchUpdate(requestList, spreadSheetId);
var updateResponse = updateRequest.Execute();
Could the order which I request the 'format' changes be affecting things maybe? Can anyone help?
As written in the documentation,
the start index is inclusive and the end index is exclusive.
So, For the first two columns, it should be
startIndex = 0,
endIndex = 2
I am building a spreadsheet that tracks work in progress as it moves through steps of a manufacturing process.
Each step of the process has a column with the total parts moved to each stage. To the left of this column is a column for number of parts moved to the stage (parts move through a few at a time).
My scrpit then takes the values in the "add" column, adds them to the "total" column, then reset the "add" column to "".
Here's the code:
function addColumns() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
// ss is now the spreadsheet the script is associated with
var sheet = ss.getSheets()[0]; // sheets are counted starting from 0
// sheet is the first worksheet in the spreadsheet
for (var i=4; i<500; i++ ) {
if(sheet.getRange(i,1).getValue()>0){ //Only run if order number not empty
//Breakout Column
var add = sheet.getRange(i,6);
var total = sheet.getRange(i,7);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
//CNC Column
var add = sheet.getRange(i,8);
var total = sheet.getRange(i,9);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
//CutSand Column
var add = sheet.getRange(i,10);
var total = sheet.getRange(i,11);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
//Lasered Column
var add = sheet.getRange(i,12);
var total = sheet.getRange(i,13);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
//To Finishing Column
var add = sheet.getRange(i,14);
var total = sheet.getRange(i,15);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
// Defective Column
var add = sheet.getRange(i,17);
var total = sheet.getRange(i,18);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
//Etsy Column
var add = sheet.getRange(i,20);
var total = sheet.getRange(i,21);
total.setValue(total.getValue() + add.getValue());
add.setValue("");
}
if(sheet.getRange(i,4).getValue()<1){i=500} //Once you find a blank order exit the loop
}
}
My code as written does accomplish this; it does exactly what I need. The problem is that since the code is accessing the spreadsheet on each loop it takes almost a full second per cell to run, and with 7 steps per order it can take minutes at a time to run through with lots of orders...
This is a pretty simple mathematical task, so there has to be a more efficient way of doing it, I just haven't been able to find the right keywords to describe what I need to do.
I am quite happy to learn whatever needs to be done, just need to know what direction to head.
Thanks in advance!
I would suggest to do something like this: (not tested)
function addColumns() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0]; // Refers to the first worksheet in the spreadsheet
var data = sheet.getDataRange().getValues(); // Acquires all values of the sheet
for (var i = 3; i < data.length; i++) { // Loop over every row
if (data[i][0].length > 0) { // Check if first column has a value
// Breakout
sheet.getRange(i+1,7).setValue(parseFloat(data[i][6]) + parseFloat(data[i][5]));
sheet.getRange(i+1,6).clear();
// Repeat code above for other columns
}
}
}
This code acquires all the data from the sheet instead of looping over a fixed amount of 500 rows. Assuming that your data starts at row 4, I've implemented this in the code above as well.
Variable data acquires all the data at one moment instead of trying to fetch values of every range (cell) all the time. I expect that this will save your script quite some time.
Because we acquire the data at once, the script sees the value as a string. Before we calculate the new value of the total column, we parse the value as a float (a number with decimals).
The code above is not tested as I don't have a sheet ready in the same format as you do but I think the logic is clear and if it doesn't work I suppose you should be able to adjust it to work for your sheet.
I have an issue with the Legend on a StackedColumn chart. I have set the following dataSeries and legend elements.
In the code, I have the following for loop to assign all the labels to the values so that they appear in the legend.
v = compositeData.dataSeries;
y = compositeData.legend;
for (i = 0; i < v.length; i++) {
dataSeries = v[i];
r += ' ynchart.addSeries("'+y[i]+'", ['+dataSeries+']);'+#NewLine();
}
When I run the code, I end up with
showing the legend except the order of the labels is not in the order I expected. Element [3] is first, followed by [0], 1 and 2. The color of the elements in the legend are in the correct order but somehow the label is not. I have no code in the script anywhere else that sorts anything. Why is the order of the legend label reordering itself and how do I fix it?
When you specify a parameter in a custom control as "multi-instance" you hand over a java.util.List. The List doesn't guarantee you any delivery sequence and that seems what is happening here. So you are probably better of handing over ONE parameter which you then split(). Of course that leans itself to the potential issue that your label and values get out of sync. So you might want to hand over a complete JSON with all included as parameter. Something like:
{ "values" : { "worldwide" : [10,20,30],
"NA" : [2,10,20],
"Europe" : [4,5,4],
"Japan" : [4,5,6]
}
}
You could consider a function that you hand the names of your fields that returns that string for you.
