When you are setting a PointTemplate
an additional ContentPresenter
will be included in the visual tree for each data point. Also, the elements defined in the template will be added to the view. That is why we suggest you to avoid using the PointTemplate
when you have a lot of data points in the series.
In your case, we can suggest using the DefaultVisualStyle
property. It is of type Style and you can set a custom style to change the appearance of the data points. Your custom style should target the native Path
component. Basically, you can set the Fill property to transparent, this way the tooltip will be visible when the mouse is over the data point.
However, keep in mind that the chart's Palette has a bigger priority than the default visual style - in other words if the Palette property is set the DefaultVisualStyle of the series will be ignored.
