How to get Series from a SeriesPoint

yes, I could create a new variable to save the Series in function "getPointNearMouse" via ChartHitInfo.Series property,
but my wish is, just use the Owner properity of SeriesPoint's base : ChartElement
to get the linkage.
So, could it be possible the Owner property of ChartElement became Public ?

Hi Lin,
We have examined this problem with our R&D team and decided not to make this property public.
The reason is that this property may be changed with future updates.
Thanks,
Andrew

see.

Hi,

has this property been changed with updates? I also want to get Owner of SeriesPoint because I have to get only SeriesPoint from suitable Series (after MouseClick event)…

Hi Anna,

Your use case is not completely clear to me. If possible, describe your requirements in greater detail or upload a small example to better illustrate your task. I will check for a suitable solution.

I use chartControl_MouseClick event and I have code like below:

C#
ChartHitInfo hit = chartControlStat.CalcHitInfo(e.X, e.Y);  
SeriesPoint point = hit.SeriesPoint;  
if (point != null && ...)  

At "if": statement I want to also check if current point is from suitable Series from my chart. I have several series on my chartControl but I want to run this event only when clicked point belongs to my "Capacity" Series for example.

In this case, you can use the ChartHitInfo.Series property to access the current Series object and compare it with Series items from the ChartControl.Series collection (see the updated code snippet below).

C#
if (point != null && hit.Series == chartControl1.Series["Capacity"]) {  
            Debug.WriteLine("passed");  
        }  

Thanks ! :)

Hi,

I also need to know what an S eries a SeriesPoint belongs to. I read all the solutions. From design point all the solutions are cumbersome. In addition, the solutions require to turn RuntimeHitTesting on based on the documentation which in turn causes "the Chart Control requires more memory resources, and its performance can decrease.".
It is not clear why a simple way of getting Series/Owner is avoided while it is already available.
Please make SeriesPoint…Owner public property.

Hi Alexander,

The original question is related to the clicked Series Point item - that's why the RuntimeHitTesting option is required. If your scenario is different, please describe your task in greater detail. I will check for a suitable solution.

I am implementing handling tooltip via ToolTipController. It has event BeforeShow in the event's handler I need to know what an Series the hovered over SeriesPoint belongs to.

C#
private void ToolTipControllerBeforeShowHandler(object sender, ToolTipControllerShowEventArgs e)  
        {  
            ToolTipController controller = sender as ToolTipController;  
            SeriesPoint seriesPoint = controller.ActiveObject as SeriesPoint;  

            IDataItem dataItem = seriesPoint?.Tag as IDataItem;  
            if (dataItem == null)  
                return;  

            seriesPoint.Owner????  
        }  

Alexander,

Do you want to show the Series name in the tooltip text? If so, add the corresponding placeholder in the Series.ToolTipPointPattern property value. Let me know if this approach is appropriate.

No, it is not enough. I have an aggregated custom made point (the point is created via custom logic that sums up some items) one per series and the rest are regular data points. I need to display in the tooltip, for the aggregated data point, items that participate in the sum. There might be several series. I am storing the list of items per series. Thus I need to know what series the hovered over point belongs to.

In this case, iterate through the Series collection to locate the corresponding SeriesPoint object.

C#
..  
            SeriesPoint seriesPoint = controller.ActiveObject as SeriesPoint;  

            foreach (Series s in chart.Series)  
                if (s.Points.Contains(seriesPoint))  
                {  
                    //TODO  
                }  

Unless I am mistaken, all Series Points belong to the same Series in your screenshot. In most cases, Series Points from other Series are drawn in different colors - this makes it easier to differentiate Series for end users. If you have only a single Series, it is not clear why it is required to obtain the Series object information at runtime.

You are correct, in the image there is only one series but chart can show several of them.
I still think that exposing Owner as public property is better solution. I really do not see any downside to it.
