Hi, I'm using the ultraChart with a CompositeChart and StepAreaChart with numericDateTimeSeries.

My chart is in a UserControl and I use personnal "AlarmAnnotation".

When I want to rewrite my annotation I use an event whitch permit the Form (father) to update the annotations.

I use 2 layer with different format for the x Axis (jj/mm/aaa and hh/mm then two diferent OuterBounds). When I write my new annotation, the OuterBound of my layer has not the good values (for Y), I tried to do

MyChart.Update()

MyChart.performLayout()

MuChart.refresh()

before adding the annotations, but that doesn't work.

Could you tell me how Could I do.

Thanks...
