Visualize active data using start date and end date using heat map

Hi Everyone,

I am working on  a requirement where i have to  highlight the warehouses that were active between 2 timestamps using heatmap.

Data available with me are

a) Warehouse name

b) Start Date

c) End date

.

Shinichiro Murakami PFA the sample data set.

I need to highlight warehouses that were active from 0h to 2h and respectively.

Thanks

Sneha
