Question

I use DotnetHighCharts TimeSeries in here : http://dotnethighcharts.codeplex.com/SourceControl/changeset/view/15464#188170

I have hourly groupped data like this:

DATE               | DATA
11.19.2012 - 06:00 | 23
11.19.2012 - 07:00 | 12
11.19.2012 - 08:00 | 34
11.19.2012 - 09:00 | 46
11.20.2012 - 08:00 | 23
11.20.2012 - 09:00 | 78

there is no data between 11.19.2012 - 09:00 – 11.20.2012 - 08:00

When I set the startPoint 11.17.2012 - 06:00 and set pointInterval 1000*60*60.

Result:

DATE               | DATA
11.19.2012 - 06:00 | 23
11.19.2012 - 07:00 | 12
11.19.2012 - 08:00 | 34
11.19.2012 - 09:00 | 46
11.19.2012 - 10:00 | 23
11.19.2012 - 11:00 | 78

There is no data between 11.19.2012 - 09:00 – 11.20.2012 - 08:00 so shifting to the left until the data is not.

How can I set the missing values to “0”. Or another way?

Using that demo link in your comment I have created this. I do not see what you are seeing with it missing times for 11/20/2012. Do you have a sample site or screenshot showing your issue?
Code (js):

chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                type: 'spline'
            },
            title: {
                text: ''
            },
            xAxis: {
                type: 'datetime'
            },
            yAxis: {
                title: {
                    text: ''
                }
            },
            plotOptions: {
                series: {
                    pointStart: Date.UTC(2012, 10, 17, 6, 0),
                    pointInterval: 1000*60*60
                }
            },
            series: [{
                name: 'Test',
                data: [
                    [Date.UTC(2012, 10, 19, 6, 0), 23],
                    [Date.UTC(2012, 10, 19, 7, 0), 12],
                    [Date.UTC(2012, 10, 19, 8, 0), 34],
                    [Date.UTC(2012, 10, 19, 9, 0), 46],
                    [Date.UTC(2012, 10, 20, 8, 0), 23],
                    [Date.UTC(2012, 10, 20, 9, 0), 78]
                    ]}]
        });
