Only 1000 lines returned for display

Hello,

I am currently working on a dashboard with Qlik Sense Desktop (version 3 - but the same issue also was there in version 2) using a Sankey extension from Qlik Branch (Qlik Branch) . The extension works very well (with 4 dimensions). But I realized that Qlik only provides 1000 lines to the extension - which can be seen in the following screenshot:

Is there some limitation in Qlik Desktop on how many lines can be displayed in a chart? If so, is there any way to work around that?

Thanks and regads!

Just extend qWidth (number of columns) and qHeight (number of rows). Note that you will (per data page) not get more than 10.000 cells, so if you have qWidth=10 you can enter a maximum of qHeight=1000

  1. initialProperties: { 
  2.   qHyperCubeDef: { 
  3.   qDimensions: [], 
  4.   qMeasures: [], 
  5.   qInitialDataFetch: [ 
  6.        { 
  7.        qWidth: 4
  8.        qHeight: 2500
  9.        } 
  10.   ] 
  11.   }

Thanks for this hint!

Is this limitiation on 10.000 cells comming from the (free) Desktop version of Qlik Sense? Or is it also in "paid" version?

Thanks again!

The limitation is per qHyperCube datapage and exists in all versions of Qlik Sense. But it also makes sense - displaying more than 10.000 data points in a visualizations

a) will not make much sense to a user (think of overcrowded visualizations)

b) will impact performance as everything is rendered in the browser.

That being said, there are ways to bring in more than 10.000 data cells by loading multiple data pages. This is advanced extension development, however in this case you should challenge yourself whether you are forcing Qlik Sense to do something it is not designed to be doing (e.g. using it as a data exportation tool).

Does this limitation also exist in QlikView? Is this so to say a common limitation or QlikSense-specific?

Thanks for your help.

This is a Qlik Sense limitation specific to its extensions (which are using qHyperCubes).
