Mouse Over my RadChart Line (ToolTip?)

[Piyush]

Hi,

I'm having severe trouble trying to make this happen but I have over 3000 points on my line chart and since I can't show each item on it, I would like to somehow have a mouseover command that will show me the values on the chart. After reading through the forums, apparently this can't be done in the RadChart.

A few questions:

1. Apparently, the following forum discussion was able to do something like this but in C#.NET. How can I make this feasible in VB.NET?

2. If I can't do this, what other alternate ways can we make this happen? I absolutely need to get this to work for me by early next week. I've noticed quite a few people asking about this. When is this going to get implemented?

And here is another example site that demonstrates this feasibility:

Help!

Hello Piyush,

As you have seen this is not supported out-of-the box for RadChart. I am afraid we will not be shipping such a feature for Q1 not to mention end of this week. Is there any problem with the work-arounds that other users have supplied in the forum?

Hi,

What's the difference between a "no support" versus the solution you provided in:

http://www.telerik.com/community/forums/aspnet-ajax/chart/mouse-over-a-scatter-plot.aspx#738877

? A little confused.

Hi Piyush,

I just checked this thread as well as the other one you mentioned. I believe my colleague Vladimir has provided an example which matches your description. Namely, it shows how to trigger an action (updating a label) upon mouse over a point chart item. I have attached an updated VB.NET version of his page to that thread, so you can check it.

In this thread, you refer to a line chart with 3000 items, where you need to show the exact value for a given point of the line. This is the functionality, which is not available in RadChart. Still, RadChart can show tooltips for line pointmarks and the mechanism is exactly the same as shown in the example I have attached to the other forum thread you have started. This is also shown in this online example. You can freely remove the RadTooltipManager if you do not need it.

Kind regards,

Hi Telerik Team

I have a Radchart line graph , I would like to display the X, Y co-ordinates as a tooltip when the user moves the mouse at any point on the line graph (not only the pointmarks but also on any point on the line graph ) .

Please let me whether this functionality is support in RadChart

Your help will be appreciated.

Thanks
