problem loading datas into analogWaveform

[aliberto]

Hi, I'm a new user to Measurement Studio for VC++. I want to plot array of doubles using a AnalogWaveform class, then when I try to load the datas into AnalogWaveform class they dosn't appear.

This is my code

int SampleCount = 20;
                 System::DateTime time;
                
                 array<double,1> ^data = gcnew array<double,1>(SampleCount);
                
                
                for(int i = 0;i<20;i++)
                {
                    data->SetValue(i*i,i);
                    //meus_pontos->SetValue(i,2,i);
                }
            
                NationalInstruments::AnalogWaveform<double> ^my_wave = gcnew NationalInstruments::AnalogWaveform<double>::FromArray1D(data);
                
                my_wave->ScaleMode = NationalInstruments::WaveformScaleMode::CreateLinearMode(2,0);
                my_wave->Timing = NationalInstruments::WaveformTiming::CreateWithNoInterval(time);

I'm  very disappointed

Hi Aliberto,

Wich Visual C++ version are you using? Wich Measurement Studio version? Is this the Enterprise or the Express package? Does any error appear when you run the program? Wich errors?
