Hi~

I added a long data to a series's XValues.
But the chart is no response.
Only integer is available?

Sample code is here.

NPointSeries m_Point;
NChart m_Chart;

m_Chart = nChartControl1.Charts[0];
m_Point = (NPointSeries)m_Chart.Series.Add(SeriesType.Point);
m_Point.UseXValues = true;

m_Point.XValues.Add(10000000000);
m_Point.Values.Add(10000000000);

Hi Inhyuk,

Thank you for pointing out this problem - it is caused by the ordinal scale on the x axis, which currently cannot handle long values as it is usually used in categorical charts that typically have values in the range 0-1000. To work around the problem you can switch the X axis in linear mode:

m_Chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = new NLinearScaleConfigurator();

We have fixed the issue in the upcoming SP of the component.

Hi~ Nevron.
Could you tell me when can I get the SP of the component?

Thank you.

Hi Inhyuk,

You just need to download the install again and reisntall the software. This should take care of the problem.

Hi Nevron~
I installed the latest version(10.9.24.12).
But It doesn't work perfectly.

I'll wait for your answer.
Thank you.


//Sample code
NPointSeries m_Point;
NChart m_Chart;

m_Chart = nChartControl1.Charts[0];
m_Point = (NPointSeries)m_Chart.Series.Add(SeriesType.Point);
m_Point.UseXValues = true;

//It does work
m_Point.XValues.Add(10000000000);
m_Point.Values.Add(10000000000);

//no response
m_Point.XValues.Add(10000000000);
m_Point.Values.Add(10000000000);
m_Point.XValues.Add(20000000000);
m_Point.Values.Add(20000000000);

//It doesn't work
m_Point.XValues.Add(200000000000000);
m_Point.Values.Add(200000000000000);

Hi Inhyuk,

Just switch the X scale configurator in linear mode:

m_Chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = new NLinearScaleConfigurator();

That will take care of the problem - otherwise you're correct the fix is not present in the ordinal scale yet.
