Slider tool not working correctly in test.iguess #65

Closed uleopold closed 10 years ago

uleopold commented 10 years ago

The slider tool is not working correctly when I try to use the Rotterdam Bospolder data set Energy Savings (mapping tag = Energy Savings). I cannot move the first slider at all and the other ones a bit.

In iguess production version it seems to work, though not so fluid and it does not referesh the layer tree correctly after closing.

I wonder if the NaN data entries also impact the tool?

The sliders are not supposed to work with null values. But I would also like to know which layer is this.

uleopold commented 10 years ago

It is the layer "Energy Savings Potential" with the mapping tag Energy Savings (see above and screenshot below). It is the Bospolder layer from Alessio.

The layer might not have NULL but NaN values which got computed by R and means Not a Number (NaN).

It should be able to deal with NULL values as it can happen that you have not computed for all spatial objects a value. If that is too complicated for now, we need to try improvements for NULL value handling later.

We nee dto find a solution. I am not sure if this is actually a problem of the slider or of the cumulative sum calulation might be done somewhere else? If so please verify that the slider works without NULL values and open a new issue which describes the correct problem.
