MPAndroidChart. How do I make LineChart plot y=0 at the x-axis without disappearing?

Question

I am on MPAndroidChart v.3.1.0 and I am using a LineChart. I have a continuous plot of data that starts at (0,0). Some Y will be positive but some points will be 0. My current graph looks like the following:

As you can see, when y=0, the line disappears then reappears when y!=0. I want the line to be continuing along the x-axis until the next positive y-value. The following is a screenshot of the desired output from another graph on web that is using a different library:

Any help is greatly appreciated!

I have tried many different settings suggested on stackOverflow but I can't seem to find any that actually work.

val dataPoints = listOf(
        Entry(1f, 2f),
        Entry(2f, 0f),
        Entry(2.5f, 0f),
        Entry(2.7f, 0f),
        Entry(3f, 4f),
        Entry(4f, 5f)
    )
val chartdata = LineData(
        LineDataSet(
            dataPoints,
            "Label",

Fixed by changing mode = LineDataSet.Mode.CUBIC_BEZIER to mode = LineDataSet.Mode.HORIZONTAL_BEZIER
