Asked On September 11, 2008 02:46 PM UTC

Hi,

I have 4 series in a chart with date-time on x-axis and prices on y-axis.

My problem is that I have data for date-time 7:00 am to 5:00 pm, then no data till next day's 7:00 am.

In the chart, if I plot 2 or more days, the chart gives me a long straight line for the date-time 5:00 pm to 7:00 am between each day.

Can I tell the chart to omit these time ranges with no data available?

In Excel, it is taken care of.

Hi Faisal,

We regret very much for the delayed response.

It is possible to disallow rendering of line at certain point by specifying the IsEmpty property of the Point to true.

Example:

series.Points[7].IsEmpty = true;

I have attached a sample that illustrates the same in this link below.

Kindly let us know if this meets your requirements. Thanks for your patience.

Hi Manohari,

Thanks for your reply and suggestion.
However, it doesn't solve my problem. I would like to omit the range on x-axis (datetime) for which I don't have any data.

So, let's say I have this data range,

1) Thursday 7:00 am - 5:00 pm
2) Friday 7:00 am - 5:00 pm
3) Saturday (no data)
4) Sunday (no data)
5) Monday 7:00 am - 11:00 am

Now, in my chart I want to see the data from Thursday to Monday. with no chart line/space shown for the time-period that I don't have any data.
So, in this case, the x-axis will not show ticks for the interval 5:00 pm to 7:00 am on Thursday/Friday... no ticks for Saturday/Sunday...

So the chart is continuous without ugly gaps (with or without a line)...

Can we manipulate the x-axis range to get this?

This functionality is already available in excel, I think.

Thanks & regards,
Faisal Memon

Hi Faisal,

Thanks for the additional information and sorry for misunderstanding your requirement.

We regret to inform you that currently we do not have support for hiding the ChartSeries without any gap between points. However we have created a Feature request in this regard and have forwarded it to our Development Team. We will get back to you regarding the timeline for implementing this feature with in a week.

Kindly let us know if you need any other information. Thanks for your patience.
