clearing the chart

[luminite]

hey guys 

in the attached vi i need to clear the chart "passing points 2" i created a property node for it but its not working, kindly tell me how to have a cleared chart whenever i start the vi and to clear the chart by pushing the button while the vi is running.

Your attachment did not attach.

Generally you wire an empty array to a History Data Property node to clear a chart.

hey lynn 

sorry heres the vi 

[altenbach]

If you want to clear during the run, the case structure and boolean needs to be inside the while loop. Right now it can only execute once at the start of the program.

[johnsold]

In addition to what altenbach said, you should move the LINX initializaton VIs outside the loop. Repeatedly initializing a serial port without ever closing it will likely cause errors and will certainly slow things down.

hey guys i tweaked my vi a lot and clear chart works. but the data rate is too high i guess and im unable to see the waveform of passing points it sqeezes too quickly, how do i increase the lenth of time axis so the waveform is visible for a while. Please see the attached vi

In the simulation, cofigure it to simulate acquisition timing. Currently, you have it set to run as fas as possible.

Whatever you are doing to the dynamic data before the graph makes no sense to me. Can you explain what you had in mind? A lof of yuor code seems unecessary. Why convert DBL to DBL, U8 to U8, etc
