Adjuste TimeInterval / Line stroke on plain hour

[Rodolphe Billottet]

Hi,

I need to display kind of financial market indicator along the day. I want to have the line stoke positionned on every hour (8:00, 9:00, 10:00 ...  )  I have set the DateTimeInterval as follow to have 1hour interval:

..PrimaryAxis.DateTimeInterval = new TimeSpan(1, 0, 0);

..PrimaryAxis.MinimumDateTimeInterval = new TimeSpan(1, 0, 0);

..PrimaryAxis.IsAutoSetRange = true;

For a normal day, the series start at 8:50 and stop at 15:35. So by default the chart should start at 8:00, finish at 16:00 and have line every hour 8:00, 9:00, 10:00 ... 14:00, 15:00, 16:00

Regurarly, for some mysterious reason, all the line are shift one minute before each hour and I have the line on 7:59 , 8:59, 9:59 .... 13:59, 14:59, 15:59    and usually, it is not stable and changes all along the day  (7:59  => 8:00 => 7:59 ... ).

Ideally I want to optimize the display, having the chart started at the first point of the serie and finish on the last point of the serie. So I have use this potion.

...Areas[0].PrimaryAxis.RangePadding = ChartRangePaddingType.Normal;

And now, as series start at 8:50 and stop at 15:35, I have all the lines shift (8:50,  9:50, 10:50 ... 14:50, 15:35).

So the question is simple how to set the line plain hour in any case  (I want 8:00  not 7:59)

I have attache some screenshot. I will try to attach a sample.

(using 11.3.0.30)

I did a sample (using one from Syncfusion 9.3.0.61 Samples). It uses some static data loaded from file.

It is just a simple one serie chart with a "Reload" button, which delete a re-create the serie with the same data.

We can see that the display of the time axis is not stable. 
Time labels are contiously changing from  HH:00  to HH:59  when I click the reload button.

It looks like a bug. Please advice..

I thanks for the reply with the code

Just you should use code which are not culture dependant. When, I have opened the sceen, the label issue was solve but there was no chart is the screen...  I had to change the date format (2013/5/12 => 2013/12/5)  to get the data back.

You set AutoSetRange = false and you fixed the DateTimeRange but actually, my screen display real time data which are updated all the day. So I want to keep the 'AutoSetRange'.

Do you have a solution with  the 'AutoSetRange' enabled ?

Or do I need disable 'AutoSetRange' and continously update the 'DateTimeRange' ?

 

Also I want the chart start 8:30 and having the first line at 9:00  and every hour. How can I do that.

I think there is a DateTimeOffset property to solve that basic issue in WinForm version. Where is that property in WPF.  Is it gone ?

Hi Muneesh,

Thanks for your update.

Unfortunately, I think there is a misunderstood on the requirement.

In your sample, the range is fixed, the chart is moving backward, and x-axis line are changing every 5 min

My initial requirement is to have the X-axis lines set on every hour (9:00  10:00 11:00  ... ) and I want an Automatic range..

Anyway, I will create a new post in the good section (WPF), reexplain the requirement, a give a new sample...

 

Thanks

Rodolphe
