Hi Rushmin,

As suho has mentioned you can write a siddhi query with a window or even
you can use a rate limiter and count number of events then write it to an
output stream. Same kind of scenario is explained in this blog post [1]
where in that blog it is calculated the average but in your case it needs
to be count.

In the dashboard when you are selecting x and y axes, select TIMESTAMP for
x axis and count for y axis. Chart is capable of identifying TIMESTAMPs
seconds and plot them in X axis.
