How to replace the axis labels with image in Xamarin.Forms Chart?
You can replace the Xamarin Chart axis labels with image using the LabelCreated event in ChartAxis and positioning the image using AbsoluteLayout.
The following code sample demonstrates how to replace the axis labels with image.
Xaml:
<AbsoluteLayout>
<AbsoluteLayout x:Name="imageLayout" />
<chart:SfChart x:Name="chart">
<chart:SfChart.PrimaryAxis>
<chart:CategoryAxis x:Name="primaryAxis"
LabelCreated="Handle_LabelCreated" />
</chart:SfChart.PrimaryAxis>
<chart:SfChart.SecondaryAxis>
<chart:NumericalAxis x:Name="secondaryAxis" />
</chart:SfChart.SecondaryAxis>
<chart:SfChart.Series>
<chart:ColumnSeries ItemsSource="{Binding SeriesData}"
XBindingPath="XValue" YBindingPath="Value" />
</chart:SfChart.Series>
</chart:SfChart>
</AbsoluteLayout>
C#:
void Handle_LabelCreated(object sender, ChartAxisLabelEventArgs e)
{
ChartAxis axis = (sender as ChartAxis);
if (axis is CategoryAxis)
{
double y = 615;
double x = chart.ValueToPoint(axis, e.Position);
Image image = new Image();
for (int i = 0; i <= images.Count; i++)
{
if (i == e.Position)
{
// Use the Images list property to set ImageSource value.
image.Source = Images[i];
image.BackgroundColor = Color.Blue;
break;
}
}
imageLayout.Children.Add(image, new Rectangle(x - 15, y, 30, 30));
}
}
