Time Series for Daily COVID-19 test Samples collected.
.
From the above plot, we can infer that, there has been an overall increasing trend in the context of number of daily covid-19 tests done.If we look closely we can notice that during the beginning of the year 2021,we can see that, there has been a decrease, it is possibly because, the active cases were lowering by that time before the second wave hit Karnataka due to which we see an increase in the subsequent times.
Time Series for Daily COVID-19 Positive test Samples.
.

Time Series for Daily Positivity Rate.
For these graph, we first calculated the ratio of daily positive cases to daily test conducted, and then found the positivity rate for each day and we plotted the rate against each day.
By analysing the graph, we can infer that the positivity rate started increasing from April-2021 till August-2020,which was the period of the covid-19 first wave, and then the rate started decreasing and by the inception of year 2021 ,it became very low, but then with the strike of wave-2,the graph started ascending towards its peak on mid May-2021,and since then we notice a decreasing trend.
