No time concept use on Grafana

I have a InfluxDB which basically has columns (value, metric name, timestamp)
I am collecting the metric values in db from time x to time y.
Now, On Grafana dashboard I want to plot a metric for different time ranges on the same panel but without timeshift.
So y axis will be value and x axis should be nothing, since I will query to select metric from time x to time y and other query would be select "same metric " from time y to time z, so that I can compare the metric values at different instances of time without having to worry about timeshift concept.
