Highcharts how to pass data to breaks option?

Question

JavaScript

When plotting a graph, I use breaks

tickInterval: 1, 
breaks: [{
from: 3000,
 to:   280
 }],

When automatically updating the data in the chart, you need to recalculate and fill in the new form and to boundaries.
I update the data like this:

chart.series[0].setData(data, false);
    chart.redraw();

how to update borders?

Answer 1

And the other day the server began to freeze a lot

Check the performance counters in the system monitor, administration, control panel (maybe problems with the HDD, disk access queues)
Perhaps this is what you need.

Answer 2

Are user groups applicable? Shared folder one or many? It's smarter to do this:
- Shared folder
- folder 1
- folder 2
and grant rights to subfolders by user groups - at least faster and easier.
About braking - you need to look carefully at the logs and act accordingly to what you read.
