How to get lowest and highest number from range

I have numbers list like this: {100, 150, 200, 250, 300, 350, 400, 450}
How to find lowest and highest number in between by given number?
Examples:
If x = 90 and desired output is 100.
if x = 120 then desired output is 100, 150
If x = 150 then desired output is 150
If x = 151 then desired output is 150, 200
If x = 420 then desired output is 400, 450
If x = 450 then desired output is 450
If x = 451 then desired output is > 450
Code:
I have tried with windows app (C#), but results are not accurate.
private void GetRangeList()
{
string givenValue = txtgivenValue.Text.ToString();
long givenValueNumber = long.Parse(txtgivenValue.Text.ToString().Trim());
var numbers = new List<long> { 100, 150, 200, 250, 300, 350, 400, 450 };
var lowest = numbers.Where(n => n <= givenValueNumber).Max().ToString();
var highest = string.Empty;
if (givenValueNumber < 450)
{
highest = numbers.Where(n => n >= givenValueNumber).Min().ToString();
}
lblOutput.Text = lowest.ToString() + ", " + highest.ToString();
}

Please, note that Max() / Min() on empty cursor throws exception:
long givenValueNumber = 90;
var numbers = new List<long> { 100, 150, 200, 250, 300 , 350 , 400 , 450 };
// n => n <= givenValueNumber condition makes the cursor empty
// Max() will throw exception
var lowest = numbers.Where(n => n <= givenValueNumber).Max();
This fact, probably, is the main difficuly in your case; however, one simple foreach loop is enough. The only (small) difficulty is to return the result in the right format for all possible cases:
// IEnumerable<long> be nice and accept any enumerable data source;
// say, array, list etc.
private static string TheRange(IEnumerable<long> data, long target) {
long? lower = null;
long? upper = null;
// all we have to do is to enumerate the data while updating lower and upper
// bounds in the process
foreach (var item in data) {
if (item <= target && (!lower.HasValue || item > lower))
lower = item;
if (item >= target && (!upper.HasValue || item < upper))
upper = item;
}
// we have upper and lower bound; time to return them in the right format
if (!lower.HasValue)
if (!upper.HasValue)
return $"Empty array";
else
return $"< {upper}";
else if (!upper.HasValue)
return $"> {lower}";
else if (lower == upper)
return $"{lower}";
else
return $"{lower}, {upper}";
}
Let's have a look:
using System.Linq; // for testing only
...
var numbers = new List<long> { 100, 150, 200, 250, 300, 350, 400, 450 };
long[] tests = new long[] {
90, 120, 150, 151, 420, 450, 451
};
string report = string.Join(Environment.NewLine, tests
.Select(test => $"{test, 3} :: {TheRange(numbers, test)}"));
Console.Write(report);
Outcome:
90 :: < 100
120 :: 100, 150
150 :: 150
151 :: 150, 200
420 :: 400, 450
450 :: 450
451 :: > 450
Finally, GetRangeList() can be implemented as follows
private void GetRangeList() {
var numbers = new List<long> { 100, 150, 200, 250, 300, 350, 400, 450 };
// 1. txtgivenValue.Text is pf type string, ToString() is redundant
// 2. Parse is smart enough to call Trim when necessary
long givenValueNumber = long.Parse(txtgivenValue.Text);
lblOutput.Text = TheRange(numbers, givenValueNumber);
}

Just use:
var belowList = numbers.Where(i => i <= x);
var aboveList = numbers.Where(i => i >= x);
long? upper = belowList.Any() ? belowList.Max() : null;
long? lower = aboveList.Any() ? belowList.Min() : null;
// now you need to handle various scenarios
if( upper.HasValue && lower.HasValue )
{
// both are found and have value
// if (upper == lower) return any
// else return both
}
else if( ! upper.HasValue )
{
// belowList was empty
string result "< " + numbers.Min();
}
else if( ! lower.HasValue )
{
// aboveList was empty
string result "> " + numbers.Max();
}
else
{
// none have value
}

dotnet highchart error, not showing data

i just curious on how to get the specific data column based on database
string[] arrLabel = new string[dt.Rows.Count];
Object[] data = new Object[dt.Rows.Count];
Object[] dataDetail = new Object[dt.Rows.Count];
String[] detail = new String[dt.Rows.Count];
var returnObject = new List<object>();
var returnColumnList = new List<object>();
int i = 0;
foreach (DataRow item in dt.Rows)
{
for (int j = 0; j < 1; j++)
{
returnColumnList.Add(new object[] {item["ATT_WF_STATUS_2"], item["ATT_WF_STATUS_3"]});
}
dataDetail = returnColumnList.ToArray();
returnObject.Add(new object[] { item["DEPARTEMENT"],dataDetail[i]});
arrLabel[i] = ((string)item["DEPARTEMENT"]);
i++;
}
data = returnObject.ToArray();
this.data = data;
this.arrLabel = arrLabel;
however, the graphic using dotnet is not showing but like this.
when i inspect element using browser
$(document).ready(function() {

});
is there any way to fix this problem ? thank you very much
Update :
i am taking this from sql database which has this similar conditionenter image description here
Another update:
this is full coding for this case

Update 2:
Can u form the data result like this :
List<object[]> returnColumnList = new List<object[]>();
string json = string.Empty;
var returnObject = new List<object>();
returnColumnList.Add(new object[] { "Depart" , "123", "345" });
returnColumnList.Add(new object[] { "Depart", "123", "345" });
foreach (var item in returnColumnList)
{
returnObject.Add(new {name = item.GetValue(0), data = (new object[] {item.GetValue(1) , item.GetValue(2)})});
}
json = new JavaScriptSerializer().Serialize(returnObject);
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
List item
The Series is not set properly.
Please do it this way :
series: [{
name: 'DO-Advisory Department',
data: [15, 32]
}, {
name: 'EDP Department',
data: [26, 5]
}, {
name: 'Enterprise Infrastructure Services Department',
data: [8, 1]

MS Chart X Axis label repeated - showing multiple points for a single item [Range Bar]

I have created a RangeBar MS Chart control that binds with a datatable. This datatable is created based on the below list data.
The problem is that x axis is showing multiple points for same item with different range.
List
MS Chart
X axis represents the 1st column of the list and Y axis values are 3rd and 4th columns. "dt" is the datatable name
Code
chChart.Series["Series1"].ChartType = SeriesChartType.RangeBar;
chChart.Series["Series1"].Points.DataBind(dt.DefaultView, "Number", "Start Time,Stop Time","ToolTip=Name,Label=Name");
Tried binding as different series but still not working.
var IETable = (dt as System.ComponentModel.IListSource).GetList();
chChart.DataBindCrossTable(IETable, "Number", "Number", "Start Time,Stop Time","");
foreach (Series sr in chChart.Series)
{
sr.ChartType = SeriesChartType.RangeBar;
sr.YValueType = ChartValueType.Time;
sr.XValueType = ChartValueType.String;
}
Is there a way to group x axis value for same item so that the bars are in same line?
Note - When using custom labels, only one value is shown for each x axis label.

Add 1 Series into the chart. Then for the Series, make sure YValuesPerPoint = 2.
Add new DataPoints so that the XValue represents the line (in the example for line ABC1, XValue = 1 and line ABC2, XValue = 2. For the DataPoint.AxisLabel you can set the label of that axis (in this case 'ABC1' and 'ABC2'). Then for the YValues, you specify values comma separated, for example 1,2 or 7,20.
Example:
chChart.Series["Series1"].Points.Add(new DataPoint() { AxisLabel = "ABC1", XValue = 1, YValues = new double[] { 2,5 } });
chChart.Series["Series1"].Points.Add(new DataPoint() { AxisLabel = "ABC1", XValue = 1, YValues = new double[] { 6,7 } });
chChart.Series["Series1"].Points.Add(new DataPoint() { AxisLabel = "ABC1", XValue = 1, YValues = new double[] { 9,10 } });
chChart.Series["Series1"].Points.Add(new DataPoint() { AxisLabel = "ABC2", XValue = 2, YValues = new double[] { 3,6 } });
chChart.Series["Series1"].Points.Add(new DataPoint() { AxisLabel = "ABC2", XValue = 2, YValues = new double[] { 7,8 } });
So the key is that the XValue must be same (double?) for all the bars on same line.

Manipulating datapoints individually for each series did the trick. Based on the index of the custom label, i modified the Xvalue of the datapoint. "vn" is a string array that has custom label names.
var IETable = (dt as System.ComponentModel.IListSource).GetList();
chChart.DataBindCrossTable(IETable, "Number","","Start Time,StopTime","");
foreach (Series sr in chChart.Series)
{
sr.ChartType = SeriesChartType.RangeBar;
sr.XValueType = ChartValueType.String;
foreach (DataPoint p in sr.Points)
{
int dpIndex=0;
// foreach unique x axis value, increment dpIndex
//ToDoCode
//aligning the datapoint's X axis value in the middle
p.XValue = dpIndex + 0.5;
}
}

Creating an object array of two value arrays dynamically – application: highcharts dotnet

I'm hoping to get a quick solution to this.
Here is a snippet of the code that works when creating a series:
Series SeriesABC2 = new Series
{
Name = '#' + HakuAlueet[1],
Data = new Data(
new object[]{
new[] { 300, 440 },
new[] { 400, 540 }
}),
PlotOptionsArearange = new PlotOptionsArearange { Visible = true, LineWidth = 0, FillOpacity = 0.3 },
Type = ChartTypes.Arearange
};
Now the plan is to make this dynamic creating the values in the object "new[] { 300, 440 }, new[] { 400, 540 }" inside .net C#. I'm quite new to C# so I'm not quite sure of the naming convention, but I seem to need to make an array object of an two value arrays. How would I go about this?
I've tried countless ways of managing this but just haven't found a solution that would be acceptable to dotnet.Highcharts. Thanks!

string[] books= source.Select(a => a.bookName).ToArray();
object[] visits = source.Select(a => (object)a.Visits).ToArray();
DotNet.Highcharts.Highcharts chart = new DotNet.Highcharts.Highcharts("chart")
.InitChart(new Chart { DefaultSeriesType = ChartTypes.Bar,
Width = 900
}).SetPlotOptions(new PlotOptions {
Bar = new PlotOptionsBar {
ColorByPoint = true,
DataLabels = new PlotOptionsBarDataLabels {
Enabled = true }
}
}).SetXAxis(new XAxis { Categories = books,
}).SetSeries(new Series
{
Data = new Data(visits),
Name = "User Book Visits"
});
lb_chart.Text = chart.ToHtmlString();
Here source contain data where I am querying some dynamic content. This is working and hope this will also help you.

xAxis : [{categories : []}], // when defining X-Axis
chart.xAxis[0].setCategories(JSON_object); // when parsing data ,from another method ,
if you want to use categories X-Axis or Y-Axis ? .bcoz the code and the chart image confusing me , any way if you want to set the categories by manually , then initially make categories as null , and assigned a array to it by using JQuery , if you loading dynamic data , then there should be a parsed json object or something semilar
