Line chart - Unable to show X-Axis labels

[Hemanth Javali]

Hi,
I am using syncfusion essential Chart to show a line graph. However the chart doesn't show the labels on my x-axis at any time when label source is specified. Following is a code snippet.

XAML:




LabelForeground="Black"
IntersectAction="Rotate"
Header="Wavelengths"
LabelsSource="{Binding Path=Wavelengths}"/>



RangePadding="Additional"
IntersectAction="Hide"
Header="Intensities"
LabelFontSize="10"/>




I add the chart series in the code behind as follows:

private void AddSeries()
{
float[] spectrum = Presenter.GetSpectraAt(sp.Row,sp.Column);
if (spectrum == null)
return;

Syncfusion.Windows.Chart.ChartSeries spectrumSeries = new Syncfusion.Windows.Chart.ChartSeries(Syncfusion.Windows.Chart.ChartTypes.Line);
spectrumSeries.DataSource = spectrum;
spectrumSeries.MouseClick += new Syncfusion.Windows.Chart.ChartMouseEventHandler(spectrumSeries_MouseClick);
spectrumSeries.MouseDown += new Syncfusion.Windows.Chart.ChartMouseEventHandler(spectrumSeries_MouseDown);

chartArea.Series.Add(spectrumSeries);
}

The series is displayed fine, also Y axis displays the values at specified intervals. However, I do not see any labels on X-axis. If I do not specify the LabelSource in the XAML, Labels from 0 onwards are displayed on X-axis.

Hi Hemanth,

Thanks for using Syncfusion Products.

Seems like you have specified the source from which the labels are to be taken alone. We should also specify the positionpath (where to place the labels) and contentpath (which labels to place).

Code snippet provided below shows this


Attached sample illustrates this behavior.

Please refer to our online documentation from the below given link that illustrates more about Chart axis label customization
