Dear Telerik Team,
I got gold historical data like this:

"2011-07-07 15:08:39" - "Valid"
"2011-07-07 15:09:20" - "Valid"
"2011-07-07 15:10:39" - "Invalid"
"2011-07-07 15:11:26" - "Valid"

and so on.

How can i build like a graph like

I also got this data only in memory as an List<object>.

Many thanks

Dear Telerik Team,
I am still working on this issue. I found the NumericalAxis Demo Project very interesting for this one. So I implemented this in my project. Everything was working well, like in the demo. Now I try to add my specific data to it.

My Method look like this :

List<DateTime> data = _scriptLogParser.GetLogEntrys();

const double hourStep = 1 / 24.0;
const double minuteStep = hourStep / 60;

double startTime = data.First().ToOADate();
double endTime = data.Last().ToOADate();

string start = data.First().ToString();
string end = data.Last().ToString();

radChart1.PlotArea.XAxis.AddRange(startTime, endTime, hourStep);

ChartSeries series = radChart1.Series[0];
series.Items.Clear();


for (double currentTime = startTime; currentTime < endTime; currentTime += minuteStep)
{
    ChartSeriesItem item = new ChartSeriesItem();
    item.XValue = currentTime * minuteStep;

    DateTime test = DateTime.FromOADate(currentTime);

    int index = data.FindIndex(p => p == DateTime.FromOADate(currentTime));
    item = new ChartSeriesItem();

    if (index >= 0)
    {
        item.YValue = 1;
    }
    else
    {
        item.YValue = 0;
    }

    series.Items.Add(item);
}

radChart1.Series.Add(series);
radChart1.DataBind();

First I get my data from "_scriptLogParser.GetLogEntrys();".

After that I set the start date and end date and interate through this in minute steps. I debug this part and it worked pretty well. But my Output is false. It looks like this :

This is not correct. I manipulate the data. So I got data from 15 till 18 o´clock. Than nothing and then the data come up at 23 o´clock. But it seems that the chart is displaying there was always data. 

Where is my wrong line ?

Thanks again.

Hi Marc,

Based on the supplied information, it is hard to determine what is causing this unwanted output. If this issue persists, you can open a formal support ticket, and send us a small project, demonstrating your setup, and showing the issue. We will debug it locally, and advise you further.

Kind regards,
Yavor
