Hi There,

As per the title I’ve got a RolloverModifier on my chart in order to utilise the snap-to-point facilities of that control. However, there is undesired behaviour when the dataseries contains points that have a Not-a-Number as a Y value as the line will still snap to the X position but the tooltip vanishes when it can’t deal with the Y value.

Could someone tell me how to either:
A/ Make the modifier jump to the next X position that isn’t a NaN


B/ Force the ToolTip to display some default text when the Y value cannot be evaluated

(or both if people are keen – I like to have options 🙂 )

All ideas are welcome
