Different Date range for different bar charts in x-axis while applying filter

I have two bar chart visualizations in kibana. One bar chart showing data for last 7 days and another one is showing data for last 30 days. I have to show x-axis for first bar chart having last 7 days only, second bar chart having 30 days only. But while selecting last 30 days in time filter the x-axis for first bar chart [last 7 days] also change into 30 days date range. How can i achieve my requirement? Please help to move.....

Kibana always uses the same time range for every visualization, subscribe to https://github.com/elastic/kibana/issues/3578 for updates when we start working on the feature (I've heard rumors is coming up in the next couple months)
