Hi,

DataLabels Not Displaying in all cases in flippedCoordinates. Based on values only its showing. I have created a sample application with some dummy data.

  1. First Series is showing the labels properly
  2. If the first value in array changed then it will show the value.
  3. If all values are 0 then also its not showing the label.

Can you check the attached file for the sample code.

When the chart is not flipped then its works fine when i am checking.

Hello,

I need to customize the text for some points on a XyScatterRenderableSeries graph. The problem is that the dataLabelProvider available for XyScatterRenderableSeries is BaseDataLabelProvider, but it doesn’t have a metaDataSelector method and I can’t do it with it. Interestingly, using LineSeriesDataLabelProvider I was able to add text for the points I needed using metadata, but another problem arose. In this case, if there is only one point on the graph, the text will not be drawn.

Here is a small example of how text is drawn for different numbers of points. https://codepen.io/PodaRocheK/pen/jOXYGMJ?editors=0011

Can you advise me on how to display text near points more correctly in the case when I use XyScatterRenderableSeries and often this text should disappear or appear near some points. Thanks a lot!
