I've modified the labelFunction and parseFunction for the horizontal axis in order to get a DD/MM dateformat. Unfortunately, I got a disturbing issue : when I ZoomOut too much, the order of my dates is inversed (from right to left) whereas the Graph stays the same... What sould I do? Thank you in advance Hi,

Replace dataprovider to the following and find some undesired results. [Bindable] public var dp:ArrayCollection = new ArrayCollection ([{ Month: "Jan", Profit: 2000} ]); you will find that loop goes on some 100 times(100 traces) and chart includes only 1 thin line on left hand side corner. hi, you wrote nice code it helps me a lot. but i find a small problem.

In my project we quite often scroll beyond the data and than fetch remaining data. It would be possible to define global minimum/maximum which will block further scrolling but I don't have time to do it... I've just changed the job and moved and I'm really busy...

Because it is continue to scrolling even if there is no data? Thanks in Advance. Can any one let me know how to prevent the X-axis scrolling if there is no data further or earlier than first node?

Only horizontal axis looks different, but previous look can be restored by setting <code>horizontalAxisStyleName="blockNumericAxis"</code> on LineChart or by creating axis renderer with <code>styleName="blockNumericAxis"</code>.

I can't tell you why this values are preserved without having a look at your code, but I can give you a workaround: Set the vertical axis minimum/maximum values to NaN after dataProvider is changed, this should cause axis range to be adjusted to data.

Hi Tiago,
Try using dataTipFunction

hitData.item should contain data related to the given column so you should be able to extract column name (category) easily.

I don't only know like you would do to put the showDataTips = "true" and to bring the category of each column. Could he/she become trained?
