Hi:
I have some problems and doubts about line chart. Can It show just once the year in the X axis? Showing 2010 and 2011 with no repeated labels? Can it hide data with special values like -1? I used the filter property but it erase the space for the chart, I want to consider it in transparent color but keeping the space.

I hope something like this:
A chart with no repeated years in X Axis and line dissapear with values "0"

Hello,

Please check you sent data. It is not correct.

Thank you.

mmm I generated a XML from my DataSet and got it, I don't know what is the correct format, can you send me an example please? thank you very much

Hello.

There is no null values in your chart.

Unfortunately, it is impossible to remove duplicate values.

Thank you.
