Changing point attribute causes it to now show

[ron.kagan]

Hello.

I'm trying to change some point appearance like marker shape / size etc...

as far as i understand, i can access the chart.Data to get the all the point attributes using the series and point index.

when i change any of the point attribute like stroke or fill, the point will not appear on the chart.

Chart.Data exposes some of the data attributes but to change visual attributes you would probably use AllSeries or Series

That doesn't give me the ability to change some of the points - i.e change all points marker above a certain spec value or change marker of every 5th point ... is this even possible ?

To change some of the points you have the following options

1) You can use the Chart.Points[series, point] API which gives you a class similar to a chart Series where you can change fill color, marker attributes, point labels, etc.

2) Use the ConditionalAttributes API, we expose an API where you can specify a condition and what attributes to change and we take care of the rest. You can also show the condition in the legend window to use highlight

You could also expose some properties directly from your CLR objects and change the templates to use some of those properties but it is more complicated.
