I have a line graph with about 300 datapoints on it. So to smooth it out we have changed the ShowPointMarks property on the
LineSeriesDefinition
to be false. This works great and makes for a really pretty chart. However I also need to be able to click the point to display data in a textblock (got this working by adding a handler for the DefaultView.ChartArea.ChartItemClick) but what I want to now is change the style of the chart item that was clicked to show a point mark to tie the visual point on the graph to the extra data I am displaying in the textblock.
Is this possible?
Cheers,

Hello James,
Unfortunately RadChart does not support selective display for the Line pointmarks at the moment and it will not be possible to achieve the desired effect.

Ok. Are there any plans in the future to add this sort of functionality? As I think it would add to the interactivty if the chart. We are trying to use the chart to control temperature data over a timescale but we would like to tie the record being displayed to a position on the chart.
This might sound like a stupid question but could we replace the x-asis with a RadSlider to give the time this would also help up with precise navigation of our temperature records because at the moment it is quite difficult to click an exact time due to the quanitity of the coordinates plotted.
Thanks,

Hello James,
Indeed such functionality would add value to the control interactivity and we will forward your feedback to our developers so they can consider it when planning the backlog for the next version of the control.
As for your second question -- unfortunately it is not possible to replace the XAxis with a slider control that would preserve its functionality.
