[Paraview] time series

[Biddiscombe, John A.]

Have a look at the time presentation on the paraview wiki under IEEE 2008 tutorial. you need XML + RequestInformation and then it should work

Hello,
I write a plugin reader. And this reader reads data which is time dependent.
So in RequestInformation I set the different values for steps and the min and max value of time like this :

for(int i=0;i<nbtimesteps;i++)
               outInfo->Append(vtkStreamingDemandDrivenPipeline::TIME_STEPS(),timeStep[i]);

timeRange[0]=time_min;
timeRange[1]=time_max;
outInfo->Set(vtkStreamingDemandDrivenPipeline::TIME_RANGE(), timeRange, 2);

nbtimsteps is the number of steps.
and timeSteps[i] is the value of the time at the step i.



In RequestData I write the following line to see the value of UPDATE_TIME_STEPS.
if(outInfo->Has(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS()))
      {
          double step = outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS())[0];
          int nSteps =
                outInfo->Length(vtkStreamingDemandDrivenPipeline::TIME_STEPS());
          double* steps =
                outInfo->Get(vtkStreamingDemandDrivenPipeline::TIME_STEPS());
          std::cout << "Step : "<<step<<endl;
          for(int i=0;i<nSteps;i++)
          {
            std::cout << "steps : "<<steps[i]<<endl;
          }
      }

 when I display outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEPS())[0] for the first time value,
I expected to have my first value of my timeStep, but I have 0.
And if I click on the next frame button in paraview, the next value is 0.1111111.

I don't understand what I am doing wrong.

Thanks,
Didier

PS : I use paraview 3.7
