Hi,

i saw the zoom example and it works :)
But now i want to add another piece of data for the same period: i have multiple data samples (in one object, with a datetime propery period and some properties which contain the data) for each day, and i want to display two or three bars and also zoom.
But when i add another sample, i loose the zoom funcionality...
I'm showing the 'periode' (period) on the X-axis.


 

SeriesMapping seriesMapping = new SeriesMapping();

 

 

ItemMapping itemMapping = new ItemMapping("SALES1", DataPointMember.YValue );

 

seriesMapping.ItemMappings.Add(itemMapping);

itemMapping =

new ItemMapping("Periode", DataPointMember.XCategory );

 

seriesMapping.ItemMappings.Add(itemMapping);

RadChart1.SeriesMappings.Add(seriesMapping);

seriesMapping =

new SeriesMapping();

 

itemMapping =

new ItemMapping("SALES2", DataPointMember.YValue);

 

seriesMapping.ItemMappings.Add(itemMapping);

itemMapping =

new ItemMapping("Periode", DataPointMember.XCategory);

 

seriesMapping.ItemMappings.Add(itemMapping);

RadChart1.SeriesMappings.Add(seriesMapping);


Am i on the right track by inserting 2 seriesmappings objects or do i have to create 1 seriesmappings object and create all the itemmappings within that seriesmappings?

Regards,
Michel

Maybe the title isn't that clear: maybe this is better:
Can i use the zoom functionality with more than one dataitem in the chart?

Hello MichelVD,

Unfortunately, at this moment it is not possible to use zoom/scroll in categorical mode (that is using XCategory) with more than one data series. Please, change DataPointMember.XCategory to DataPointMember.XValue in the ItemMappings. This will allow you to use zoom/scroll. Our developers are aware of this limitation and they will research the possibilities to fix it in the future versions of the control.

Best regards,
