Hi,
I've a program running on labview that perform hardaware control on a DSA (dynamic signal analyzer) to do spectrum acquisation over a range of frequency. My program currently works fine, I've my data acquire from the DSA and displayed in the xy graph in the front panel. I'm using a loop to perform iteration for data acquisation at different frequency decades, and shift register to store those data at each iteration, in order to have a final plot in the XY graph with the full range of frequency measured. The problem I'm facing is in the display of XY graph, it seems that in the front panel when I right click the mouse and select data operation->clear graph, it only clear the data displayed on the plot from the front panel, but not the ones in my block diagram, therefore when a run another measurement let says with less frequency range, the xy graph plot in front panel overlapped data from the previous measurement and current measurement. Is there a way to clean the previous data, see attach in picture portion of block diagram and front panel.
