1. Modify the background color or set the background picture
Background color settings require two setMarginsColor and setBackgroundColor.
2. setAxisTitleTextSize(16); //Set the text size of the axis title
3. setChartTitleTextSize(20); //Set chart title text size
4. setLabelsTextSize(15); //Set axis label text size
5. setLegendTextSize(15); //Set Legend Text Size
6. renderer.setChartTitle("Set column name"); //Set column name
7. renderer.setXTitle ("XX"); //Set X-axis name
8. renderer.setYTitle ("YY"); //Set Y axis name
9. renderer.setXAxisMin(0.5); //Set X-axis minimum value to 0.5
10. renderer.setXAxisMax(5.5); //Set maximum X-axis value to 5
11. renderer.setYAxisMin(0); //Set the minimum value of Y axis to 0
12. renderer.setYAxisMax(500); //Set Y-axis maximum to 500
13. renderer.setDisplayChartValues(true); //Set whether the value is displayed above the column
14. renderer.setShowGrid(true); //Set whether to display the grid in the chart
15. renderer.setXLabels(0); //Set the number of scale labels displayed on the X-axis
16. If you want to display custom labels on the X-axis, first set renderer.setXLabels(0); then we want renderer.addTextLabel() to add in a loop
17. renderer.setXLabelsAlign(Align.RIGHT); //Set the relative position relationship between the scale lines and the X-axis
18. renderer.setYLabelsAlign(Align.RIGHT); //Set the relative position relationship between the scale line and the Y axis
19. renderer.setZoomButtonsVisible(true); //Set scalable
20. renderer.setPanLimits (newdouble[] {0, 20, 0, 140}); //Set the pull range
21. renderer.setZoomLimits (newdouble[] {0.5, 20, 1, 150}); //Set zoom range
22. renderer.setRange(newdouble[]{0d, 5d, 0d, 100d}); //Set chart's view range
23. renderer.setFitLegend(true); //Set whether to show legend
24. renderer.setClickEnabled(true)//Set whether sliding, zooming in and out is possible;
25.ChartView.repaint(); redraw
26. For AChartEngine click events, double-click events, and sliding events, all can be resolved with custom events, but it is important to note that renderer.setClickEnabled(false) is set first;
27. If the graphics are distorted after they are added, renderer.setInScroll(true) can be set;
28.renderer.setGridColor(); //Set grid color
29.renderer.setAxesColor();//Set axis color
30.Renderer.setShowLegend(true); //Show bottom description
31.Renderer.setShowLabels(false); //Do not display labels
32.renderer.setLegendTextSize(20); //Set the text size of the lower left corner annotation
33.renderer.setZoomButtonsVisible(true); //Set display zoom in and out button
34.renderer.setZoomEnabled(false); //Settings do not allow zooming in or out.
35.renderer.setChartTitleTextSize(30); //Set the text size of the chart title
36.renderer.setChartTitle("Statistical Results"); //Set the title of the chart to show at the top center by default
37.renderer.setLabelsTextSize(20); //font size of marker text on pie charts
38.renderer.setLabelsColor(Color.WHITE); //Color of marker text on pie charts
39.renderer.setPanEnabled(false); //Set whether panning is possible
40.renderer.setDisplayValues(true); //Whether to display values
41.renderer.setClickEnabled(true); //Set whether clickable
