How to create a chart that allows the user to click on the specific chart area,
when user click on the specific chart are I want to fire some event on that,
like I want to display more detailed chart on the item user have clicked.
I have used Webchart, MicrosoftChart but both provides chart as image so no clickable area there any alternate?
The microsoft chart control definitely does support click-through. Check this article out at 4guysfromrolla.

In Orange, is there a way for the report viewer to automatically show the visualizations without having to click the report button within the individual widget?
Thanks.
No.
This functionality could be added, but what would trigger adding the report entry? Any change in the widget? Even, for instance, changing transparency in the scatter plot? OK, this would be too extreme - but where's the line? Consider the network widget, where the user zooms in and out... If it is not perfectly clear in what situations is the report generated automatically and when does the user have to click, it's better to have only manual reporting.
I created timeline chart using chaps link library and now moving to use vis.js . I am facing the following issues. appreciate any pointers in getting it addressed
1) In chaps link library there was option to show the navigation button, which i couldn't bring it on the chart using vis.js.
2)On selecting an item on the timeline chart how to get the data associated with the item.In chaps link library I was able to get the data using timeline.getData() method and from that i was able to get the data for the selection. Is there any api available which could get me the data of the selected item.
There are no navigation buttons available which can be shown by using the vis.js API. But you can create your own navigation buttons. You can use the timeline methods moveTo(time [, options]) and setWindow(start, end [, options]).
The first one moves the timeline to a certain date, and the second one can be used to zoom in and out by setting the parameter accordingly.
We are using telerik charting demo version.
we want to know if we can drill down from telerik pie chart to telerik stacked bar chart or not.
We don't want drill down to a specific portion of the pie. But we have scenarios where we have 5 portions of data for a group in pie chart. When we click on the pie chart, it will drill us down to each group members' stacked bar where each bar has same 5 portion of data belonging to them.
Is it possible with telerik charts ?
I am using asp.net web application.
Need a suggestion: which are good chart controls ? I searched lot on the internet and am confused. I want controls which don't have limitations. I don't want to not be able to drill down on pie or something like that.
Help is appreciated.
thanks,
Drilldown is achieved by initiating a (partial) postback so you can modify the control on the server: http://demos.telerik.com/aspnet-ajax/htmlchart/examples/drilldownchart/defaultcs.aspx.
Instead of changing field names, you can simply hide the current chart and show another one with the desired properties and series.
I have a single series bar chart created programmatically in codebehind which I would like to display the Y point value (somewhere above the bar, or maybe as a tooltip) when the user hovers their mouse over a bar.
Is there a native onmouseover event for the bars of the chart, or is it something that should be added through series.MapAreaAttributes?
Thanks!
Edit
After some experimenting I've found the points.tooltip attribute which I can add at the same time I add the point which will do what I want it to do, but it would still be nice to know if you can capture events for the bars, just for future reference.
From Show all series' values in stacked bars mouseover (ASP.NET CHART)
series.MapAreaAttributes = "onmouseover=""showTooltip('#VALY');"""
Where your showTooltip function would do as you required.
