Hi Khalid,Greetings from Syncfusion. We are not aware of
which series and axis type are used to render a chart, so we have plotted the
given point with the NumericAxis
and line type series and it renders properly and ensured no issue is found at
our end. We have attached the sample below which is used in the testing phase,
if you still facing the same issue, please try to reproduce the issue in the
attached sample and get back to us. It will be more helpful to us to provide a
solution sooner.Regards,Yuvaraj.Attachment: f176101_320d3197.zip
