In chart, the x-axis labels are overlapping, when chart data is big. I have used "step" property as follows :
xAxis: {
labels:{
step: (stepVal ? stepVal : 0),
},
}
I calculate the value of stepVal, depending upon data. This resolves the issue of overlapping labels on x-axis. But, when I zoom the chart, I want to see all the labels on x-axis. How to get it?
In Highcharts 3.0 you can use
chart.xAxis[0].update({
labels: {
step: newValue
}
}
for updating step. Just setting new value in options for new chart won't work.
I believe what you are looking for is this..

You would need to change the xAxis labels steps in the event of a zoom action. You will need to determine how many labels you would want to show, based on how many labels are visible as a result of the zoom.
