Highchart for Android library x-range chart How to use dynamic y-axis data

Question

While using the x-range high chart library, the x-axis contains date information data for each part, and the y-axis contains the title of each part. The y-axis contains a different number of titles per account rather than a fixed number. On the web, you can process it as an Arraylist, but in the Android example, you need to put one Map for each y-axis line, how should you handle it?
