Android XYPlot 圖形底部標簽大小更改？

Question

在構建 gradle 中使用 androidplot 庫的 Android 圖形視圖加載小部件

implementation "com.androidplot:androidplot-core:1.5.7"

使用以下基於網絡調用的 getresponse 代碼動態創建圖表。

在類文件中我的示例代碼...

val plot = XYPlot(context, "")
    val h = context.resources.getDimension(R.dimen.sample_widget_height).toInt()
    val w = context.resources.getDimension(R.dimen.sample_widget_width).toInt()

   plot.graph.setMargins(100f, 0f, 0f, 16f)
   plot.graph.setPadding(0f, 0f, 0f, 0f)
   plot.graph.gridInsets.left = 100f
   plot.graph.gridInsets.top = 0f
   plot.graph.gridInsets.right = 0f
   plot.graph.gridInsets.bottom = 40f                                        
   plot.legend.textPaint.textSize = 1f

   plot.linesPerRangeLabel = 8
   plot.linesPerDomainLabel = 8

   plot.graph.setSize(Size.FILL)

   plot.measure(w, h);
   plot.layout(0, 0, w, h);

   plot.graph.position(0f, HorizontalPositioning.ABSOLUTE_FROM_LEFT, 0f,
                      VerticalPositioning.ABSOLUTE_FROM_TOP, Anchor.LEFT_TOP)

   val series1Numbers = mutableListOf<Int>()

       series1Numbers.add(item.TotalScore)
       series2Numbers.add(0)

 plot.graph.setLineLabelEdges(XYGraphWidget.Edge.LEFT, XYGraphWidget.Edge.BOTTOM)

     plot.legend.setVisible(false)
     plot.getGraph().linesPerDomainLabel = 5
     plot.getGraph().linesPerRangeLabel = 5

                                        }
  }

  plot.addSeries(series1, series1Format)
  plot.addSeries(series2, series2Format)

 val bitmap: Bitmap = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888)
 plot.draw(Canvas(bitmap))
 remoteViews!!.setImageViewBitmap(R.id.img_graph_view, bitmap)
appWidgetManager!!.updateAppWidget(appWidgetId, remoteViews)

我試圖減少底部標簽顯示的文字大小不起作用，它彼此重疊如何減少底部標簽文字大小？

setTextsize 在下面的代碼中使用

 plot.getGraph().getLineLabelStyle(XYGraphWidget.Edge.LEFT).getPaint().textSize = 16f
