I am in process of evaluating this product for our use. I am using VS2015, C#, winforms.
I am finding it difficult to get the vertical axis to invert so that increasing values go down instead of up.
This code:
nChartControl1.Visible = false;
nChartControl1.Charts.Clear();
nChartControl1.Legends.Clear();
NCartesianChart chart = new NCartesianChart();
nChartControl1.Charts.Add(chart);
NChart m_Chart = nChartControl1.Charts[0];
NLineSeries m_Line = (NLineSeries)m_Chart.Series.Add(SeriesType.Line);
m_Line.DataLabelStyle.Visible = false;
m_Line.MarkerStyle.Visible = false;
m_Line.UseXValues = true;
NAxis axis = chart.Axis(StandardAxis.PrimaryX);
axis.View = new NRangeAxisView(new NRange1DD(0.2, 2000.0));
NLogarithmicScaleConfigurator logarithmicScale = new NLogarithmicScaleConfigurator();
logarithmicScale.MajorGridStyle.SetShowAtWall(ChartWallType.Back, true);
logarithmicScale.MinorGridStyle.LineStyle.Pattern = LinePattern.Dot;
logarithmicScale.MinorGridStyle.SetShowAtWall(ChartWallType.Back, true);
logarithmicScale.MinorTickCount = 8;
logarithmicScale.MajorTickMode = MajorTickMode.CustomStep;
logarithmicScale.CustomStep = 1;
m_Chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = logarithmicScale;
m_Line.Values.AddRange(mapTheDoubles);
m_Line.XValues.AddRange(secondCurve);
NRange1DD nr = new NRange1DD(4950.0, 5000.0);
//nr.Invert();
chart.Axis(StandardAxis.PrimaryY).View = new NRangeAxisView(nr, true, true);
nChartControl1.Refresh();
nChartControl1.Visible = true;
..produces this result:
82% of original size (was 610x619) - Click to enlarge
I want the vertical axis inverted to put 4950 at the top, and 5000 at the bottom, with the data following that orientation.
When I uncomment the nr.Invert() line and run it, this is the results:
82% of original size (was 610x619) - Click to enlarge
Alternative results, by doing this some other way, fail to change the first image orientation.
What's the secret to getting this to work with an inverted Y axis?
Thanks.
