Can I modify the XY-Graph in Matlab-Simulnk R2016a so that I can follow the end of my output line clearly?

As the figure below shows, I can not follow the end of my output line. Could it be possible to make the tail of the line disappear after a lapse of certain time (such as a comet in the sky)?
Or to adapt the XY-Graph to provide the end of line with a head, which has a different color from the main line?
Or is there any another suggestion to display the line clearly?
Thank you for any help!

Hi Mahfoud,
You can modify the XY-Graph in Simulink R2016a. The XY graph that we see is a s-function. If you right click on the block and go to Mask -> Look under Mask, you will see that the s-function "sfunxy.m" is used.
You can modify this s-function according to your requirement. For example, you can clear the graph periodically or provide a marker for the head of the graph. The s-function uses MATLAB syntax, so you can use all the available properties of a MATLAB figure.
Another much simpler workaround would be to use a MATLAB function block. It is fairly straightforward to write to MATLAB function block to plot a x-y graph. If you are not much familiar with using s-functions, I would recommend to use a MATLAB function block.
Regards,
Vaibhav
