Hi,
Finally I have decided another alternative to waveform graph. Now I use
a waveform chart with a history length of 86400 points but only is
visible 60 points at the same time because I represent minute by minute
on the waveform chart (I plot each second now). And I show to user the
scroll bar of x-axis so the user can view all the data corresponding to
the last day (24 hours) because the history length of the chart keeps
data of 86400 points (a day)
😉 and then I don't need to use data
decimation method.
One question... When I move the scroll bar of x-axis at the same time
another vi is plotting over it, sometimes (not always) I can see
how LV not redraws well the waveform chart... why? If I do what you
say, trying defering panel updates, seeting it to true before and to
false after... LV doesn't redraw it each second as I want.
Thanks to everybody for helping me,
ToNi.
