How to get PointMarks to show on a line graph

[Mark]

When the complaint came in that my line graph didn't have visible points at the values, I thought it would be an easy fix.

Somehow, I can't seem to make it happen.

The meat of the code is here:

'Create a series

Dim oSeries As Telerik.Charting.ChartSeries = New Telerik.Charting.ChartSeries()

radChart.Series.Add(oSeries)
 


'make it a line

oSeries.Type = ChartSeriesType.Line

radChart.Series(0).Appearance.FillStyle.MainColor = Color.Red


'add some data

radChart.Series(0).AddItem(3.5)

radChart.Series(0).AddItem(4.5)

radChart.Series(0).AddItem(6.5)

radChart.Series(0).AddItem(8.5)


' try everything and anything to get the points to show up

radChart.Series(0).Appearance.PointMark.Visible = True

radChart.Series(0).Appearance.PointMark.Dimensions.AutoSize = False

radChart.Series(0).Appearance.PointMark.Dimensions.Width.Value = 20

radChart.Series(0).Appearance.PointMark.Dimensions.Height.Value = 20

radChart.Series(0).Appearance.PointMark.FillStyle.FillType = Styles.FillType.Solid

radChart.Series(0).Appearance.PointMark.Figure = Styles.DefaultFigures.Diamond

I'm using the 4.1.6 version of the dll date 3/10/09

I've been searching the Forum for a mention of a similar problem - how bad is your problem when nobody on the internet has ever had it before?

I've attached a jpg of the output.

Please let me know what add't information would be helpful.

Thank you in advance for the help.

Hello Mark,

As I inspected your code snippet I saw that you are doing everything right to show the PointMark. There is one thing that you need to know - PointMarks of Lines are unvisible and transparent by default. What you need to add is some Color for your PointMarks:

RadChart1.Series[0].Appearance.PointMark.FillStyle.MainColor = Color.Red;

Hope this helps.

Best wishes,

Well done.

Thank you.

The documentation mentions that visible = false by default, but says NOTHING about transparency or color required. Would have been nice to know this before I wasted an hour trying every property before finding this post.
I guess I should consider myself lucky I only lost an hour this time. Wish you guys would improve your documentation.
