vb.net chart: How to get AxisX.CustomLabels in sync with AxisX.MajorTickMark

Question

As shown in the code, I get CustomLabels displayed, but they are not on the MajorTickMarks defined in the ChartArea. How do I get this in sync?

vb.net
Dim from_X, to_X As Date
from_X = myClass.get_DateOfWeek(CInt(yearkNo), CInt(weekNo), DayOfWeek.Monday)
'Last week from mainTable
weekNo = mainTable.Columns(mainTable.Columns.Count - 1).ColumnName.Split(CChar("/"))(0).Substring(2, 2)
yearkNo = mainTable.Columns(mainTable.Columns.Count - 1).ColumnName.Split(CChar("/"))(1).Substring(0, 4)
to_X = myClass.get_DateOfWeek(CInt(yearkNo), CInt(weekNo), DayOfWeek.Saturday)

Dim ints as integer = CInt(DateDiff(DateInterval.WeekOfYear, from_X, to_X, FirstDayOfWeek.Monday, FirstWeekOfYear.FirstFullWeek))
Dim xdate(ints) As Date 'is looped through and the date of the respective week is added.

newchart(chart1) 'create new chart
Dim chartArea1 As New ChartArea("Default")
chart1.ChartAreas.Add(chartArea1)

chart1.ChartAreas("Default").AxisX.IntervalType = DateTimeIntervalType.Weeks
chart1.ChartAreas("Default").AxisX.Interval = 1
chart1.ChartAreas("Default").AxisX.LabelAutoFitStyle = LabelAutoFitStyles.DecreaseFont
chart1.ChartAreas("Default").AxisX.LabelAutoFitMinFontSize = 7
chart1.ChartAreas("Default").AxisX.LabelStyle.Font = My.Settings.fontbold8
chart1.ChartAreas("Default").AxisX.LabelStyle.Angle = 90
chart1.ChartAreas("Default").AxisX.MajorTickMark.Enabled = True
chart1.ChartAreas("Default").AxisX.MinorTickMark.Enabled = False
chart1.ChartAreas("Default").AxisX.Minimum = from_X.ToOADate()'44443
chart1.ChartAreas("Default").AxisX.Maximum = to_X.ToOADate()'44828
chart1.ChartAreas("Default").AxisX.IsMarginVisible = False

chart1.Series.Add("K").Color = ColorTranslator.FromHtml("#297AB7") 'MattBlau colorx(0)
chart1.Series("K").Points.DataBindXY(xdate, yValues)

chart1.ChartAreas("Default").AxisX.CustomLabels.Clear()
For intVal As Integer = 0 To ints - 1
    Debug.Print(intVal & " - " & Format(xdate(intVal), "yyyy-MM-dd"))
    Select Case intVal
        Case 0, 5, 10, 15, 20, ints - 2
            chart1.ChartAreas("Default").AxisX.CustomLabels.Add(xdate(intVal).ToOADate(), xdate(ints - 1).ToOADate(), myClass.get_WeekNumber(xdate(intVal)) & "/" & xdate(intVal).Year)
    End Select
Next

It looks now like here in the picture: https://www.spearhead-home.com/Downloads/20220517_XAchseKWs.jpg

Found now a solution for me: AxisX.IntervalType, AxisX.Minimum, AxisX.Maximum must match the series DataBindXY(xValues, yValues)

Dim ints as integer = CInt(DateDiff(DateInterval.WeekOfYear, von_X, bis_X, _
  FirstDayOfWeek.Monday, FirstWeekOfYear.FirstFullWeek))
Dim xdate(ints) As Date 'is looped through and the date of the respective week is added.
Dim xInt(ints) As Integer 'is looped through and the numbers of the interval-count added.
 
chart1.ChartAreas("Default").AxisX.IntervalType = DateTimeIntervalType.NotSet
chart1.ChartAreas("Default").AxisX.Interval = 1
chart1.ChartAreas("Default").AxisX.Minimum = 0
chart1.ChartAreas("Default").AxisX.Maximum = ints - 1
 
chart1.ChartAreas("Default").AxisX.CustomLabels.Clear()
For intVal As Integer = 0 To ints - 1
Dim kw_run As String = ""
kw_run = myClass.set_WeekFormat(myClass.get_WeekNumber(xdate(intVal)), xdate( _
  intVal), True)
'result looks like: 2022/20
chart1.ChartAreas("Default").AxisX.CustomLabels.Add(intVal, intVal + 1, kw_run, _
  0, LabelMarkStyle.None)
Next
 
'Series
chart1.Series("mySeries").Points.DataBindXY(xInt, yValues)

Answer 1

You need to give the body a height, or else it'll be the elements height, that's why you can't move top or bottom, since the parent (body) is only 200px, since that's all there is. Where the parent doesn't have a height property, it'll automatically adjust to it's content height, 200px in this case. Also, the top property from body can be removed.

You could add height: 100vh; to your body, that'll be the 100%/units height of the view port.

The calc() function you have is taking 50% of it's parent size, then substracting 100px, which in your case is 50% of your element. That'll center the element with percentages.

An alternative to your centering solution could be:

.container {
  background-color: lightgray;
  opacity: 50%;
  width: 200px;
  height: 200px;
  left: 50%;
  top: 50%;
  position: relative;
  transform: translate(-50%, -50%);
}

This will move your container 50% left of parents width, 50% from the top of parent and then, with transform: translate() move it -50% of it's own size X and Y

Answer 2

• You need to give a height to body.
• If parent div has a position relative then for setting div according to parent you should give a child div to position absolute.

   * {
            box-sizing: border-box;
            padding: 0;
            margin: 0;
        }
        
        html {
            font-size: 62.5%;
        }
        
        body {
            background-image: url("wallpaper.png");
            background-size: cover;
            background-repeat: no-repeat;
            position: relative;
            top: 0px;
            height: 100vh;
        }
        
        .container {
            background-color: lightgray;
            opacity: 50%;
            width: 200px;
            height: 200px;
            left: 50%;
            top: 50%;
            position: absolute;
            transform: translate(-50%, -50%);
        }

<div class="container">
    <div class="container-name"></div>
     <div class="container-stats"></div>
</div>

Answer 3

HTML:

<div class="wrap-center">
    <div class="container">
            <div class="container-name"></div>
            <div class="container-stats"></div>
    </div>
</div>

CSS:

.container {
    background-color: lightgray;
    opacity: 50%;
    width: 200px;
    height: 200px;
}

.wrap-center {
    display: flex;
    justify-content: center;
    align-items: center;
    width: 100%;
    min-height: 500px;
}
