Am trying to plot spline graph for the no of passed/failed testcases and grouping them based on hour/date/month/year and I am getting this value as irr
I simply used a minTickInterval of 28 days to account for short Feb months. The tickIntervals automatically adjust to 1 month.
minTickInterval
tickIntervals
xAxis: { type: 'datetime', minTickInterval: 28*24*3600*1000 }
Works great for me.
