Rencana survei Highcharts
Contoh berikut menunjukkan diagram pengukuran.
Pada bagian sebelumnya kita sudah tahu sintaks konfigurasi dasar Highcharts. Mari kita lihat konfigurasi lainnya.
konfigurasi
chart.type Konfigurasi
Mengkonfigurasi jenis grafik 'mengukur'. chart.type menggambarkan jenis bagan. Nilai default adalah "line".
var chart = { type: 'guage' };
Konfigurasi panel
panel hanya tersedia dalam plot polar dan sudut ukur. Objek dikonfigurasi ini memegang umum pilihan kombinasi sumbu x dan y-minggu. Setiap sumbu x dan y-axis dapat dihubungkan ke panel dengan indeks.
var pane = { startAngle: -150, // x轴或测量轴的开始度数,以度数的方式给出。0是北 endAngle: 150 //x轴极坐标或角度轴的最终度数,以度数的方式给出。0是北 };
