wrong date with different zoom

[nordsonne]

Hi,

i have a small problem with the Highslide chart tooltip.
The last point on xAxis got a "wrong" date with different zoom "steps".

i take this as an example because the Demo Gallery is down in the moment

get the last possible Point on the Graph, you get "Monday, May 9 2011" and "0.6945", use the slider an zoom in, now the date ist "Tuesday, May 10 2011" and again "0.6945".

is this there any possibilty to prevent this behavior, maybe disable the tooltip with such a zoomlevel or the the rangeslider to a max Value and don't allow to get a bigger range ?

best regards

There's nothing wrong here. Highcharts does this because of performance issue, it's called dataGrouping (http://www.highcharts.com/stock/ref/#pl ... taGrouping). You can try to disable dataGrouping but I don't recommend this with bigger amount of data.
