Highstock change xAxis minRange after chart is loaded

Question

I am truing to change the minRange on xAxis after chart has been loaded. i have tried these with no success :

chart.xAxis[0].minRange
chart.xAxis.minRange
chart.xAxis[0].options.minRange
chart.xAxis.options.minRange

none of them works.bu setting the minTickInterval like this works :

chart.xAxis[0].options.minTickInterval

so how can i change minRange at runtime?

UPDATE:I should have mentioned that my axis is type of datetime

UPDATE 2: ok i found the problem, i have this in my code :

    $.each(Analyzer.chart.series, function (index, item) {
        item.setData([]);
    });

to clear the series data, so i can load new data. if i comment this peace of code setting minRange works.

so ??? how to clear series data so that i can change minRange too ????

UPDATE 3: ok i moved the cod in update2 to before setting minRange.... and walla it works :D

for future references : you should set minRange after you have cleared the series data otherwise it wont works.

Answer 1

Try to set the isDirty flag of the xAxis object, and then run the redraw method:

    chart.xAxis[0].minRange = 20;
    chart.xAxis[0].isDirty = true;
    chart.redraw();

Edit: It should also work when your x axis is of type "datetime". See updated example: http://jsfiddle.net/NnW5G/
