Hi @saadkhurshidmalik , I figured out.

You have to do this:

                                    <com.wordplat.ikvstockchart.InteractiveKLineLayout
                                            android:id="@+id/main_chart"
                                            android:layout_width="match_parent"
                                            android:layout_height="match_parent"
                                            >
                                            
                                            <RadioGroup
                                                    android:id="@+id/But_Group"
                                                    android:layout_width="match_parent"
                                                    android:layout_height="@dimen/stock_index_tab_height"
                                                    android:layout_gravity="bottom"
                                                    android:layout_marginLeft="10dp"
                                                    android:layout_marginBottom="90dp"
                                                    android:orientation="horizontal"
                                                    >
                                                    
                                                    <RadioButton
                                                            android:id="@+id/MACD_But"

                                                            />
                                                    
                                                    <RadioButton

                                                            style="@style/StockIndexTabStyle"
                                                            android:layout_height="match_parent"
