Android Question MPAndroidCharts - Spurious horizontal lines

AlpVir said:

I started using the library MPAndroidCharts in question but in the example (post # 7)
https://www.b4x.com/android/forum/t...st-library-v1-18-in-post-1.58017/#post-366818
but the final result of the graph in the upper left shows some spurious horizontal lines. How are they born and above all how to avoid them appearing ?

Maybe try this:

B4X:

mlc1.HorizontalGridColorLeft = Colors.Cyan
mlc1.HorizontalGridColorRight = Colors.Transparent

Maybe I haven't made myself clear.
In post # 1 I reported the result (a part of a screenshot, as it appears on my smartphone) of the example of which I have provided the link also in post # 1.
In post # 3 I highlighted in red the horizontal lines that MUST NOT APPEAR (they generate confusion and are in any case an error)
In post # 5 I reported another example with horizontal lines that I call "spurious", useless, that create confusion.
The library is very interesting, very good for the rest and I would like to use it.
But I don't know how to remedy the defect reported here.
The suggestion to use multilinechart does not seem valid to me because I am interested in viewing ONLY ONE GRAPH. Also the reference to the color (mlc1.HorizontalGridColorLeft = Colors.Cyan) makes me suspect that my problem has not been understood (I have indicated the spurious lines in red).
Can you help me simply by correcting the example cited ?
Thank you in advance.
