How can I use the compass function, changing the vector position during the time?

Hi. I'm using serial port to collect data and I need to plot it using the fucntion compass. For each data sample, I need to update the plot using compass (arrows emanating from the origin). I'm using this code now:

axes(handles.axes3)
h=compass(eletrodo1, eletrodo2);
hold on;
drawnow;

The problem is, when I update the plot with new data, the past data still remains on the plot. I don't know how to clean the plot for each new data point. Can someone help me? Thank you.

I can’t say for sure, but deleting the hold on call might do what you want.
