charts and graphs

[Bildavid]

hi all

I have an application that gives me a real time signal that should be displayed continuously . Well, when i connect the wire that is giving me a signal to a waveform graph,  the signal keeps appearing properly until the graph fills and looks like your compressing a spring . 

i have tried to turn the X autoscale ON and OFF and the same for Y but nothing revealed . 

BUT when i use a waveform chart it works well and i can see a real time signal .

any help ?

I think you might want to read the difference between a graph and a chart.  You will understand why stuff is happening.
