It turned out that your were right. It seems to happen because I use a dataset that I bind to and I asign a label column. Here the labels are strings and not as in the dataset DateTime objects. I ended up inserting a new "label" column in the dataset. Here I'm using different format strings to get the format of choise.

Thanks Uli

oh, and if you do want to implement IRenderLabel, that might turn out to be the easiest solution:

string IRenderLabel.ToString(Hashtable context)

{

string dateString = context["ITEM_LABEL"].ToString();

return DateTime.Parse(dateString).ToString("MMM-dd-yyyy");

}

perhaps the column's DataType from your datasource is string and not DateTime?

I think I need more information to diagnose the problem, perhaps a screenshot and a description of your datasource, or better yet, a sample project.

Anybody any idea on this one?  Any help appreciated. Thanks uli

I got the same problem, but I couldn't fix it by setting

TreatDateTimeAsString = false;

I'm using a line chart on a composite chart with a DateTime x-Axis with:

xAxis.Labels.ItemFormat = AxisItemLabelFormat.Custom;

xAxis.Labels.ItemFormatString =

"<ITEM_LABEL:MMM-dd-yyyy>"; //I tried different FormatStrings

xAxis.TickmarkStyle = AxisTickStyle.Smart;

xAxis.Labels.Layout.Behavior = AxisLabelLayoutBehaviors.None;

Am I doing something wrong? Did I forget something? Or does this just not work with Smart-TickStyle? Do I have to Implement a IRenderLabel?

What I try to do is to display the weekdays if they are meaningful.
