Creating more than 3 lines with different styles in ChartView programatically

[JayantSharma777]

I am facing problem in adding more than 3 lineSpecs so that my chartView which is of line type can have more than 3 different lines.I can not do this programatically because i do not get the option of adding lines in the chartView object.

Module

• compose
• views
• compose-m2
• compose-m3
• core (select if none of the above apply)

To reproduce
set up a chartView in xml .
Initialize the chartView object in your activity and link it with your xml,

Expected behaviour
I want to add more than 3 different lines in my chartView of line type.

Android versions
12,13

Hello! ChartView is a host component. It doesn’t implement Chart. You can add LineSpecs programmatically by using (chartView.chart as LineChart).lines, where chartView is a reference to your ChartView instance.

Now in this line chart, I am trying to add styles for my custom line, and i want to add a drawable for my point and change it's style, but in you implementation the point is of type Component which is an abstract class, how can i extend it or use it,I have asked you this before as well and you told me to do it programatically then too but i couldn't find a way. can you make that clear as well?

This is how i am adding the lineSpec in lines in ChartView

Please use ShapeComponent and Shapes.drawableShape: ShapeComponent(Shapes.drawableShape(...), ...).
