Change granularity of a Trend dinamically

ChartFactor Toolkit
1

Hi, I’m building an app in react and I’m including the toolkit library for data visualization, I’m using a trend chart to show the distribution of records over time and I’m just trying the dragFilter feature to select a time window and use it as a filter, but when the time window is small the chart doesn’t look good, how can I change the granularity of the trend group so that the selected time window looks better?

Got it, but, do you want to calculate the granularity automatically according to the selected date ranges? or maybe do you want to specify the granularity yourself?.

Actually, i want to use my custom configuration, to specify when to use MONTH, YEAR or other granularity.

Got it, well, you can check the drillIn break points to define your own breakpoints, like this:

// Define the path for the group by
let drill = {
    'trendElementId': {
        'group1': {
            "YEAR": 3, // the time window should have at least 3 years
            "MONTH": 3, // the time window should have at least 3 months
            "DAY": 3, // the time window should have at least 3 days
            "HOUR": 5, // the time window should have at least 5 hours
            "MINUTE": 5, // the time window should have at least 5 minutes
        }
   }
}
cf.create().imanager().set('drill',drill).element('chart').execute()
