Perpustakaan semacam ini sering digunakan untuk membuat grafik dan plot ketika menulis dan merancang strategi.
Belajar dari desain fungsi ekspor dari
$. PlotMultRecords
Digunakan untuk menggambar grafik K-line, parameter yang dirancang: cfgName, seriesName, records, extension。
cfgName: sebagai grafik tunggal, nama objek yang dikonfigurasi;
seriesName: nama seri data yang perlu digambar K-line pada saat ini;
catatan: data K-line yang dikirimkan;
ekstensi: informasi konfigurasi dimensi grafik, misalnya: pass{layout: 'single', col: 6, height: '600px'}
, yaitu, meminta grafik dengan nama objek yang dikonfigurasi dari cfgName untuk hanya menampilkan lebar: 6, tinggi: 600px.
$. PlotMultLine Digunakan untuk menggambar garis, dirancang parameter: cfgName, seriesName, titik, ts, ekstensi cfgName: sebagai grafik tunggal, nama objek yang dikonfigurasi; seriesName: nama seri data yang perlu digambar garis pada saat ini; titik: nilai urutan titik pada garis yang akan ditarik; ts: time stamp, yaitu nilai pada sumbu waktu X; ekstensi: informasi konfigurasi dimensi grafik.
$. PlotMultHLine
Digunakan untuk menggambar garis horizontal; parameter yang dirancang: cfgNama, nilai, label, warna, gaya
cfgName: objek yang dikonfigurasi dalam grafik;
nilai: nilai ordinat dari garis horizontal;
label: teks yang ditampilkan pada garis horizontal;
warna: warna garis;
gaya: gaya garis, misalnya:Solid ShortDash ShortDot ShortDashDot ShortDashDotDot Dot Dash LongDash DashDot LongDashDot LongDashDotDot
.
$. PlotMultTitle Digunakan untuk memodifikasi judul dan subjudul grafik; Parameter yang dirancang: cfgNama, judul, chartTitle cfgName: nama objek yang dikonfigurasi; Judul: subjudul; chartTitle: judul dari chart.
$. PlotMultFlag Digunakan untuk menggambar bendera; parameter yang dirancang: cfgNama, seriNama, ts, teks, judul, bentuk, warna, onSeriesName cfgName: objek yang dikonfigurasi dalam grafik; seriName: nama seri data; ts: Stempel waktu; teks: teks di bendera; Judul: judul bendera; bentuk: bentuk bendera; warna: warna bendera; onSeriesName: didasarkan pada seri data yang akan ditampilkan; nilainya adalah id seri data.
$. DapatkanArrCfg Digunakan untuk mengembalikan array objek yang dikonfigurasi dari grafik.
Untuk pemahaman yang mudah, saya menulis komentar langsung pada fungsi tes, menjelaskan apa yang dilakukan setiap panggilan fungsi.

Anda dapat melihat bahwa hanya dengan satu baris panggilan fungsi, Anda dapat dengan mudah menggambar grafik, dan Anda dapat menampilkan beberapa jenis grafik pada saat yang sama.

Di sini saya hanya menggunakan ini untuk memulai diskusi dan berpikir tentang topik. Jika Anda tertarik, Anda dapat meningkatkan jenis grafik yang didukung (seperti grafik kedalaman pasar, grafik batang dan grafik bulat, dll.) dan terus meningkatkan.
