Too many points in dataset. Number of points is 401...

Hello,

 

depending on the time frame I use for retrieving my data it happens that the query exceeds the default size of 400 elements giving the following message:

 

"Too many points in dataset. Number of points is 401 and current limit is 400. Please modify the query to return fewer points or increase the limit"

 

Therefore I searched a bit and found the option "Intervals: ...", so I tried the following:

 

getDefaultConfig: function(){

return{

DataShape: 'TimeSeries',

DataQueryMode: CS.Extensibility.Enums.DataQueryMode.ModePlotValues,

//DataQueryMode: CS.Extensibility.Enums.DataQueryMode.ModeMarkers,

//DataQueryMode: CS.Extensibility.Enums.DataQueryMode.ModeEvents,

Height: 250, 

Width: 250,

Intervals: 2000

   }; 

}

 

But no matter which DataQueryMode I use of the above mentioned, neither the method nor the number I put for Intervals does change anything in the returned data, which I receive in my

 

function dataUpdate(data)

 

. I can even put 20 and still I have the error message from the top.

 

According to "PI Vision 2017 Custom Extension Creation", I would like to use ModePlotValues as I would like to obtain a number of interpolated values over this period.

 

How can I achieve that?

 

Thanks a lot for your time,

 

Jörn
