Hi Yordan,

We have analyzed your query. As of now we can’t give image in stock events, but we can achieve requirements using annotations which support image. However in annotation we can’t bind the description. Also, we are facing some issues in providing annotation for DateTime Axis. We have already logged a bug task on this. Please find the task below.

Task: https://www.syncfusion.com/feedback/15958/annotation-doesnot-work-in-stockchart-for-datetime-axis

The fix will be available in our weekly patch release which is scheduled to be rolled out on or before July 21, 2020. We appreciate your patience until then.

If you have any more specification/precise replication procedure or a scenario to be tested, you can add it as a comment in the portal.

Thanks,

Srihari.

Hello dear syncfusion support. Well.. I can not provide code snippet since I am not sure how to make this thing, nor I can do screenshot since I am not sure how to make a code for it, and this is the question actually, so I will try to clarify, by more explanation ( please do not hesitate to ask me additionally to clarify if needed ).

So..

Let say that I have an array with events.
These events have a specific date when they happen, they as well have a description.

Each of these events must be visualized on the chart in the specific date with a picture which is a property of the event object, and when I move my mouse over it - to show the description.

for instance the follow class :

public class TChartEvent
{

public string imagePath;
public DateTime XchartValue;

public string description;

public string YchartValue;
}
public List<TChartEvent > events = new List<TChartEvent >();

I am not sure if this is sufficient, please tell me if you need additional clarification.
