The plotted data on the graph disappear when clearing graphs!??

[HFZ]

Hi folks

I got this vi, with two graphs, and one chart. I got this chart coz i want the data plots to strip in the graphs.

but when the VI runs, and i pres stop and run again, the data plot disappears, they are then beeing plotted in the back ground or something like that.!

Also when clearing the graphs the data plottet disappears.

How can I overcome that ?
 

regards

Hello Zamzam,

after clicking "clear Graph", the graph is cleared and new data are plotted... So what's the problem? At least here with LV7.1 it's running.
And after setting "autoscale" for x- and y-axis in the chart, it also displays the data correctly.

Hi Gerd

It sounds weared ,

I.m running labview, 7,1 and its not working as u menstion it.

I cant se the (now plotted data) after clearing the graph, somehow the graph are running to  quickly compared to the new data, or the graph still runs with its x-scale update while clearing the graphs.

Hello Zamzam,

same again:
1) I click "Clear" when the graphs are not filled with data: graphs are cleared, new data appear from left and fill the graphs.

2) I click "clear" when the graphs are "filled" (the x-scrollbar shows more data the display is showing): graphs get cleared, new data appear from left and fill the graph again...

3) I click "stop" at any time: vi stops, actual display stays.
