DataMarker's label background color

[Michael]

Hi all,

I encountered an problem which didn't exist in earlier versions.

Settings the datamarker's background to clear has no effect any more, whereas settings to all other colors works as expected.

This line has no effect:

series.DataMarker.LabelStyle.BackgroundColor = UIColor.Clear;

Regards

Michael

As of now we can resolve this issue by setting the UseSeriesPalette property value as false. 

 

Please refer the below code snippet:

Hi Luca, 

  

From the shared screenshot, we suspect that you are setting DataMarker LabelPosition as outer in sample level. So that only labels are cropped due to lesser space in the corners. You can resolve this issue by setting LabelPosition as Auto. Refer the below UG link for more information.

hi, i will try but on iphone 7 with the same code is working fine, why?

just on iphone X and XR i have this issue.

i need to have the marker outer because the marker color is the same of the area.. so if i put belowe the marked will be not visible

if i put outer what I expect is that the chart scale in order to see the marker.. am i wrong? 

thanks

Hi Alberto, 

 

We have checked the reported scenario in iPhone 7 and iPhone XR, but we get the same output in both. As we said before, labels are cropped due to lesser space in the corners if we set DataMarker LabelPosition as outer in sample level which is the behavior. To avoid the cropping issue at corners when the data marker labels are placed outside we can use the RangePadding as an Additional or PlotOffset property to apply some padding to the axis line. We have prepared the sample to achieve it, you can download from the below location.

Please find the code snippet below for the same. 

 

[XAML] 

<chart:SfChart.PrimaryAxis> 

    <chart:NumericalAxis RangePadding="Additional"  PlotOffset=”20”> 

    </chart:NumericalAxis> 

</chart:SfChart.PrimaryAxis> 

 

<chart:SfChart.SecondaryAxis> 

    <chart:NumericalAxis RangePadding="Additional" PlotOffset=”20”> 

    </chart:NumericalAxis> 

</chart:SfChart.SecondaryAxis>
