Using d3 in for loop


Using d3 in for loop

seems to work fine The biggest issue that I see is that you are running asynchronous code in a for loop.
d3.tsv() is asynchronous and returns a Promise
code :
for(var i = 0; i < 3; i++) {
    d3.tsv('//mydata/from/a/slow/server.tsv')
        .then(function callbackExecutesWhenDataReturned() {
            console.log('in callback, iteration: ' + i);
        });
    console.log('in for loop, iteration: ' + i);
}
in for loop, iteration: 1
in for loop, iteration: 2
in for loop, iteration: 3
in callback, iteration: 3 or undefined
in callback, iteration: 3 or undefined
in callback, iteration: 3 or undefined
Promise.all([
    d3.tsv('path/to/file1.tsv),
    d3.tsv('path/to/file2.tsv),
    d3.tsv('path/to/file3.tsv)
]).then(function processResponses(myArrayOfThreeResponses) {
    myArrayOfThreeResponses.forEach(function(response, index) {
        show_inst_now(response);
        Loaded_Data[index] = response;
    });
});

PHP while loop for HTML Generation: Should I Check Array values at each While Loop Iteration or use Post-Loop String Pro

it should still fix some issue I'm working on a PHP-written html calendar that writes each day of the month inside a while loop. , Here's another solution:
code :
$day = 1;
$strings = array();
while($day < 31) {
    if (array_key_exists($day, $array)) {
        $strings[$day] = $array['$day'] . " spots available";
    } else {
        $strings[$day] = "No spots available for this date";
    }
    $day += 1;
}
foreach ($strings as $day => $string) {
    echo '<td title="' . $string . '">' . $day . '</td>';
}

Does that help If you want m1 to be the cumulative list of means, then the last line needs to be indented to be inside the final while block.
code :
while d <335:     
    d = d + 1     
    y = fpsd[d]     
    y1 = y1 + [y]       
    m = np.mean(y1)
    m1 = m1 + [m]
Outer loop to loop over each row and nested loop to loop over each character

will be helpful for those in need You're attempting to compare a string (Layout.ROWS[i]) to a char. You should iterate over the Strings in your array, and for each such String iterate over the chars that make it up. While this can be acheived with a while loop, using for loops would be much cleaner:
code :
public static int count(char d) {
    int sum = 0; 

    // Iterate over all the strings in Layout.ROWS:
    for (String str : Layout.ROWS) {
        // Iterate over the chars of the string:
        for (int i = 0; i < str.length(); ++i) {
            if (d == str.charAt(i)) {
                ++sum;
            }
        }
    }
    return sum;
}
My loop works like this: loop, script, loop. I want this: loop, loop, code. The ForgottenServer 0.3.6

hop of those help? Can you just move the "set storage" to a second loop after the first? That's the only way that you'll be able to send all of the messages before doing any of the set storage calls.
code :
for _, pid in ipairs(getPlayersOnline()) do 
  if getCreatureStorage(pid, tmp[i].storeDamage) > -1 then 
    doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, getPlayerName(pid)..': '..getCreatureStorage(pid, 11005))
  end
end
for _, pid in ipairs(getPlayersOnline()) do 
  doCreatureSetStorage(pid, tmp[i].storeDamage, -1) 
end

hope this fix your issue I have several row in a table in db and every row related with three tables and every table has many rows. when i loop main table rows i also loop three tables rows now if one of tables has a content in row then i want to prevent showing entire sub that loop only which contain a value. , This method uses relationship count comparison.
Controller
code :
public function classWiseResult(Request $request){
    $students = Students::where('class',$request->class)
        ->withCount(['firstTerm as firstTermPromoted' => function($q) {
            $q->where('number', '>', 32);
        }])
        ->withCount('firstTerm as firstTermAllCount')
        ->withCount(['secondTerm as secondTermPromoted' => function($q) {
            $q->where('number', '>', 32);
        }])
        ->withCount('secondTerm as secondTermAllCount')
        ->withCount(['finalTerm as finalTermPromoted' => function($q) {
            $q->where('number', '>', 32);
        }])
        ->withCount('finalTerm as finalTermAllCount')
        ->with('firstTerm')
        ->with('secondTerm')
        ->with('finalTerm')
        ->get();

    return view('admin.showResult.show',compact('students'));
}
@foreach($students as $student)
    @if($student->firstTermPromoted == $student->firstTermAllCount
        && $student->secondTermPromoted == $student->secondTermAllCount
        && $student->finalTermPromoted == $student->finalTermAllCount)

        {{ "Promoted" }}

    @else

        {{ "Not Promoted" }}

    @endif
@endforeach
