Legend showing multiple times

[Molnár István]

I have a log file that contains (IP, datetime, pingtime).  I read the data from the log.txt file, I group them and after that I create the chart series.

The problem: the legend shows multiple times the name of IP.

How can I correct this problem?

PS: I attached a screenshot too.

Hi Molnar Istvan,  

 

Our development team is working on this with high priority, since this approach is related with chart legend placement and takes more time than expected, we will update you the status of this in 2 business days 7th August 2020. We deeply regret for the inconvenience caused.

Hi Molnar Istvan, 

 

Thank you for your patience.  

   

We have analyzed your query and code; we suspect that you can resolve this by using following code example. In that, we have created the chart series from groupedList instead of you have created listIPs. And legend items created based on the series count. Please find the following code example.  

 

 

Code Snippet: 

 

 

foreach (var ips in int m = 0; m < groupedList.ToList().Count; m++)
            { 

                 var ips = groupedList[m]; 

                 chartSeries[m] = new ChartSeries(ips, ChartSeriesType.Bubble); 

                for (int i = 0; i < listIPs.Count; i++)
                {
                    if (ips == listIPs[i].IPAddress)
                    {
                        chartSeries[i] = new ChartSeries(listIPs[i].IPAddress, ChartSeriesType.Bubble);
                        chartSeries[m].Points.Add(Convert.ToDateTime(listIPs[i].datetime.ToString()), Convert.ToDouble(listIPs[i].pingtime.ToString()));
                        chartSeries[m].PointsToolTipFormat = "DateTime:{3}";
                    }
                }
            }
