Good Morning,

I have set my chart's bounds mode to fit yet when I add an x axis title I noticed the bars are bigger, yet the axes don't grow in size with the bars. I haven't added any extra information besides the table so th ebars shouldn't grow like such.

Is there a certain property I need to set to a certain value to stop this?

When comparing whatI have done with the examples, I cannot see a difference but there is a good possibility I have missed something.

Any help would be greatly appreciated.

Thank you in advance for your time,

David

Hi David,

Can you post the code you're testing with along with an image showing the problem - I don't think I understand the question properly...

Best regards,

Bob

Thank you for your quick reply Bob,

Sorry I have attached the screenshots as so I can explain my situation a little clearer.

Basically the bar on the very left is sitting over the Y axis and Y axis labels and the bar on the far right is also outside its bounds.

However, when I remove the x axis label, this is no longer so.

My axis label code is simply:

xAxisLabel.Title.Angle = new NScaleLabelAngle(0);
xAxisLabel.Title.RulerAlignment = HorzAlign.Center;
xAxisLabel.Title.ContentAlignment = System.Drawing.ContentAlignment.MiddleCenter;
chart.Charts[0].Axis(StandardAxis.PrimaryX).ScaleConfigurator = xAxisLabel;
xAxisLabel.Title.RulerOffset = new NLength(0, NRelativeUnit.ParentPercentage);
xAxisLabel.Title.TextStyle.FontStyle.Style = System.Drawing.FontStyle.Bold;
xAxisLabel.LabelGenerationMode = LabelGenerationMode.SingleLevel;
xAxisLabel.RoundToTickMax = false;
xAxisLabel.RoundToTickMin = false;
xAxisLabel.AutoLabels = false;

I am not sure what I could have done wrong.

Thank you once again for your help Bob, I hope I haven't given you too great a headache,

David

Hi David,

 

No worries

 

The problem is that you're applying a linear scale to the X axis. I was able to reproduce the same behavior with the following code:

 

NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];

NBarSeries bar = new NBarSeries();

bar.Values.AddRange(new double[] { 12, 15, 16 });

bar.InflateMargins = true;

chart.Series.Add(bar);

 

NLinearScaleConfigurator linearScale = new NLinearScaleConfigurator();

chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = linearScale;

Generally, the component is behaving according to specification as the ordinal scale (which is the default X axis for series that do not use X values - like XY scatters) will inflate the original range (0-2) to (-0.5, 2.5), which produces the bar that does not overwrite the axis.

 

The simplest way to fix this is to revise the code and change the place where you create a NLinearScaleConfigurator and use a NOrdinalScaleConfigurator instead - I'm not sure why you use it, but generally it is necessary when you want to have scale decoration based on a double arithmetic instead of integer (which is the case with ordinal scales). The other way around is to apply a range inflate to the configurator.

 

Hope this helps - let me know if the problem persists.

Best regards,
Bob

Thank you very much for your help, once again, Bob.

The NOrdinalScaleConfigurator worked a treat

I knew it must have been something I had done, just couldn't pick it because it wasn't happening on another chart but my values were integers, thus I when comparing the code between the two, all the property settings looked identical, I didn't think about the values the charts were outputting.

This is something I will never forget!

Thank you again Bob,

David

Hi,

After using the code above it also fixed my issue, yay!

But how do I make the X Axis start at 1 (and not 0?

Thank you!

Hi John,

 

You can override the label value formatter:

 

public class NCustomValueFormatter : NNumericValueFormatter

{

    public override string FormatValue(object obj)

    {

        double val = (double)obj;

        return base.FormatValue(val + 1);

    }

}

 

private void Form1_Load(object sender, EventArgs e)

{

    NChart chart = nChartControl1.Charts[0];

   

    NBarSeries bar = new NBarSeries();

    bar.Values.Add(10);

    bar.Values.Add(20);

    bar.Values.Add(30);

   

    chart.Series.Add(bar);

   

    NOrdinalScaleConfigurator scale = chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator as NOrdinalScaleConfigurator;

    scale.LabelValueFormatter = new NCustomValueFormatter();

}

Let me know if you meet any problems...

Best regards,
Bob
