Hi,
please,
i want to know how can compare between multiple series (line type )
I'm just following up to see if the suggested helped you or if you have any further questions on the matter.
I see your point. In case of missing values, at some point in the xAxis you can use the unknownValuePlotting property. When set to linearInterpolate it will plot the unknown value as the midpoint between surrounding known values using linear interpolation.
Look at this example I prepared for you:

Please let me know if you have further questions on the matter.
we can continue in this thread please
and i am trying to define multiple series on the same chart, but series points are the same (not all have the same points in XAxis so the chart displayed like the following image) :
Please clarify what is exactly your scenario and your goal. You can define multiple series on the same chart - if this is what you want please refer to http://www.igniteui.com/data-chart/category-series (you can change the chart type to line from the dropdown menu).
P.S. I see that email from the same domain has the following thread opened: http://ko.infragistics.com/community/forums/t/96718.aspx, which seems to be the same. If this is the case please let me know at which thread you prefer to continue discussion.
