Hi,

We are building interactive visualization to compare the sales data over timelion, ask is to compare the sales today to yesterday(this duration should be customizable), which i am able to achieve by having a offset on the timelion expression something like below. I want the offset to be dynamic. Do we have an option to build this with the help of drop down, something like when i choose 1 week, actual and the offset duration change to 1 week without having to choose the expression manually.

es(index=logs\*, metric=cardinality:sales.id).label('Sales Current'), .es(index=logs\*, metric=cardinality:sales.id, offset=-1d).label('Sales Yesterday')

Hi @nagabhushan.tr

Using Timelion directly is not achievable. What you can do is to use Canvas to add a dropdown filter with a simple table (using the `csv` function expression with a set of key, value rows like: `last week,-1w`) to create a filter and then add a line chart with the mentioned timelion query including the selected value from the dropdown in the offset parameter
