Problem with Wave form chart

Hi 

I used ni daq and displayed a live data values on a  waveform chat ...and also i am  able to save the data as .lvm format . 

Now I have to creat two modes to my chart , Live data mode and History mode and show the saved values again on the chart. how to do this ? And also I want to display Auto scale as an icon as shown on the figure . Also I  want  to change the range of the y -axis by using horizontal pointer slide as shown on the figure. 

 

I attached  my code and the front pannel which  I have to implement. 

 Tnx

Hi Cherkose,

for the Autoscale, you can use the property node X Scale>Scale Fit.

 

When you want to display data from a file, you have to read them first and then make multiplot.

If you want to use different "States" of your programm (either History or Live data) use a state machine or a simple case structure to switch between the states.

 

regards

Tobias
