我正在使用
MPAndroidChart library.我想在MPAndroidChart中自定义图例.在MPAndroidChart库中,我试图设置图例的位置.通过给定代码legend.setPosition(LegendPosition.BELOW_CHART_CENTER)但无法执行此操作.我必须设置图例如下图所示
帮助将是欣赏
解决方法
请查找给定答案
MPAndroidChart – Legend labels are being cut off.我已经根据您的问题提供了答案.
寻找给定代码肯定会帮助你.
您必须按照以下步骤使用其图例颜色和标签实现自定义图例：
寻找给定代码肯定会帮助你.
您必须按照以下步骤使用其图例颜色和标签实现自定义图例：
步骤1
Legend legend = mChart.getLegend();
第2步
int colorcodes[] = legend.Colors();
第3步
for (int i = 0; i < legend.Colors().length-1; i++) {
.....
.....
}
第4步
然后你必须采取水平或垂直的一个布局,并获得图例颜色代码和图例标签,并根据图例长度创建布局和标签.代码示例如下：
LinearLayout.LayoutParams parms_left_layout = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
parms_left_layout.weight = 1F;
LinearLayout left_layout = new LinearLayout(context);
left_layout.setorientation(LinearLayout.HORIZONTAL);
left_layout.setGravity(Gravity.CENTER);
left_layout.setLayoutParams(parms_left_layout);
LinearLayout.LayoutParams parms_legen_layout = new LinearLayout.LayoutParams(
20,20);
parms_legen_layout.setMargins(0,20,0);
LinearLayout legend_layout = new LinearLayout(context);
legend_layout.setLayoutParams(parms_legen_layout);
legend_layout.setorientation(LinearLayout.HORIZONTAL);
legend_layout.setBackgroundColor(colorcodes[i]);
left_layout.addView(legend_layout);
TextView txt_unit = new TextView(context);
txt_unit.setText(legend.getLabel(i));
left_layout.addView(txt_unit);
LinearLayout.LayoutParams parms_middle_layout = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
parms_middle_layout.weight = 1F;
LinearLayout middle_layout = new LinearLayout(this);
middle_layout.setorientation(LinearLayout.HORIZONTAL);
middle_layout.setGravity(Gravity.CENTER);
middle_layout.setLayoutParams(parms_middle_layout);
TextView txt_leads = new TextView(this);
txt_leads.setText("450");
middle_layout.addView(txt_leads);
LinearLayout.LayoutParams parms_right_layout = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
parms_right_layout.weight = 1F;
LinearLayout right_layout = new LinearLayout(this);
right_layout.setorientation(LinearLayout.HORIZONTAL);
right_layout.setGravity(Gravity.CENTER);
right_layout.setLayoutParams(parms_right_layout);
TextView txt_leads_percentage = new TextView(this);
txt_leads_percentage.setText(munit_percentage_list.get(i) + "");
right_layout.addView(txt_leads_percentage);
childlayout.addView(left_layout);
childlayout.addView(middle_layout);
childlayout.addView(right_layout);
然后将您(在运行时创建的子布局)添加到主布局.
