Plumbing question for Ben (chart Q actually)

[gstanczak]

Ben I am perhaps in need another "jiggle the handle" solution.  I tried writing to a few different property nodes for a WFChart that is "acting a-fool" with no results.  Each update mode seems to have its own problems.  Specifically, in sweep mode (or is it scope?  I forgot immediately after the CLAD) there sometimes appears a second refresh cursor when the x-axis scale is changed, sections of vertical-horizontal lines on the chart come and go as the cursor passes or the front panel is scrolled, the waveform itself clears when the cursor reached the end of the plot area and acts like scope and then returns to sweep sometime later or the waveform itself is thick (as it is set to be) but then is very thin is some sections.  In scroll mode when DAQ begins a few samples of data show up on the far end of the plot before beginning normal left-to-write plotting.

I have found some previous posts about video cards in laptops not being sufficient but the posts were pretty old, and it happens on a good desktop too.

Any suggestions?  I am considering using a graph, its pretty slow acquisition and I figure there wouldn't be too much of a performance hit.  No?

You gurus rock!

P.S. - My brother (a plumber) really appreciated your plumbing story with the power auger.

Can you post a simplified example that duplicates that behaviour?

It looks a lot like what we were talking about in the "What makes chart go wonky" thread. NI reported a CAR but it has been hard geeting examples they can use to enusre they fixed it.

so can you post a simple demo?

Absolutely.  I have 2 that I will try to simplify.  The other VI crashes when the chart x-axis scroll bar is visible, and does not crash when the scroll bar is not visible.  Needless to say, that one was tough to debug.

This will take a little time...
