Hi, all I am doing now pulse oximeter project in labview. I have got signals from oximeter and waveform is generated in waveform graph. But not a smooth one. I need a smooth waveform like the image attached here. What are the applicable methods to solve this problem?

What does Labview exactly means 'flattening' and 'unflattening' that is used in explaining type cast's operation.Thanks in advance!!
