LineSeries Empty Point Behavoir

[Dana]

Is there a way of controlling the way empty [null] points are handled with ChartView?

I was looking to move from RadChart to the ChartView in one of my applications mainly from a performance point of view
[we are plotting c. 8000 points on each chart]

As far as I can tell this behaves like the LinearSparkline in 'ShowAsZero' mode, ideally I need to show a gap.

Thanks

Hello,

RadChartView currently supports empty values represented as null and displays them as zeroes, otherwise said we support currently only empty point behavior Zero from RadChart.

We are planning to include the Drop and Gap modes from RadChart, unfortunately with the current implementation we use a single polyline segment to represent the series. We are aware of these issues and have planned the inclusion of EmptyPointBehavior, however, it will take some time to do it.

aah well, back to a normal radchart then :)

Keep at it though guys, the new charts have real potential.

+1.
I want to use the ChartView because it provide TrackBall behavior (Chart don't support it - am i right?), but i need the Gap behavior for null values in series. Its a strong recomendation for trends in industry application (like in SCADA-systems) - zero it's a normal value (for example - temperature. pressure, etc), but null is not.
Can you say - for that time you can make this gap behavior to ChartView, approximately?

PS Sorry for my terrible English.

Hello Dmitry,

We are planning to enhance the empty values behavior for Q2 2012 in about four months. As for trackball -- indeed RadChart does not support trackball info and there is no equivalent to it in RadChart.

And I hope in SL-version you will make it too, in Q2?

Hello Dmitry,

Yes, once ready, the empty values behavior will be available in both WPF and Silverlight.

Hello Evgenia,

I want to bind my whole dataTable to chart and in that datatable some values is null. in reporting version 5.1.11.928 it is working as expected but in new release 2012 Q1 it is give me below error.

"Cannot set Column <Columnname> to be null.Please Use DBNull instead."

can you please help me for this?, or any suggestion from you.

Thanks

[Evgenia]

Hi Thomas,

Unfortunately the way our reporting chart currently works does not allow you to have an approximated values. The charting engine works with DBNull, but the reporting requires these values to be null. Unfortunately this is done internally and there is no way that you can workaround it.
Depending on your exact scenario I can suggest that you set the null-s as 0-s or filter them using the Filters of the Chart item .

It is in our future development plans to change this behavior but as for now I can't provide you an exact timeframe.

Hello telerik Team

i am having problem or issue with telerik Kendo UI Chart

In Kendo UI WEB, the line chart is connected between the points without data. Instead, the line should be broken and restart with new markers and lines like we do in the WPF UI. is there any property like EmptyPointBehaviour.Gap in Telerik kendo UI for WEB for more understanding i attached file plz look forward

Hello,

Similar behavior could be achieved using series.missingValues of Kendo UI Chart.

3 years have passed, is this feature implemented now?

Hello Andrey,

RadChartView for WPF supports empty data points. You can take a look at the Empty Values ChartView demo to see how to achieve the desired effect. Basically, you can set the value of the empty data point to Null. This way the chart won't draw it on the plot area.

Hello Martin!

I know that RadChartView supports empty data points, but I was asking about implementing this:

3 years have passed, and it's a huge time.

Hi Andrey,

Currently, the empty points behavior is supported by the chartview suite, however, there is only a gap mode. In order to achieve the effect of the RadChart's Drop mode you can just set the empty values to 0.
