Can we use ZoomIn to specify a date range we want currently visible.
We want to show the last 7 days only by default
Hi.You can use navigation parameters.
initialDisplayUnit: "1 d",
initialDisplayPeriod: "7 d",
Here is a reference to our documentation navigation.initialDisplayPeriod :https://zoomcharts.com/developers/en/time-chart/api-reference/settings.html#doc_navigation.initialDisplayPeriod
Also you should use initialDisplayAnchor as by default it uses "newestData", meaning that last 7 days will be calculated from latest data point timestamp. Change it accordingly for your needs.https://zoomcharts.com/developers/en/time-chart/api-reference/settings.html#doc_navigation.initialDisplayAnchor
