Marker label based on data type

[ivaylopenevmg]

Question

Hello, in my implementation I need to show a label that represents the data type in the marker along side with the numeric value.

Looking at the source code the object we can work with is:

public data class Point(
    val entry: LineCartesianLayerModel.Entry,
    val canvasY: Float,
    val color: Int,
  )

So there is no way to map a label to a Point, the work around I use is to map labels with the colors. Example:

fun getDataNameFromColor(color: Int): String {
    return when (color) {
        -8832, -672691 -> "Grid"
        -8735836 -> "Solar"
        -12488092 -> "Injection"
        ...
        else -> ""
    }
}

Is there a better way to do this?

Hello, @ivaylopenevmg. There are more robust ways to do this, but the best one depends on the specifics.

Do the series have the same x values, or is it possible for one series to have a gap where another one doesn't have it, leading to a case where e.g. there are three lines, but the marker highlights only two points at a given x value?

Hello, @Gowsky we have no gaps in the series, and they can have same x values. Zero values can also be possible.

In that case, you can do this based on the order of the elements in targets. Targets are guaranteed to be added in the order of the series. Extras may be needed if series are shown/hidden dynamically.

Adding a seriesIndex property to the Entry classes was brought up previously. It's not needed here, but it could make things slightly simpler. Feel free to open a feature request if you'd find this helpful.

Hello @Gowsky thank you for your reply. We do show/hide series dynamically. Could you please clarify on what do you mean by "Extras"?

Extras are covered in the guide. Let us know if you have any specific questions.
