Publicat: 2013-06-12

Dynamic Spline HighChart Exemplu cu mai multe valori ale axei Y - Sfaturi Crunchify

Highcharts este o bibliotecă de diagrame scrisă în pur HTML5/JavaScript, care oferă diagrame intuitive, interactive site-ului sau aplicației dvs. web. Highcharts acceptă în prezent linie, spline, zonă, arespline, coloană, bară, plăcintă, împrăștiere, calibre unghiulare, arearange, areasplinerange, columnrange, bubble, box plot, bare de eroare, pâlnie, cascadă și diagrame polare.

Recent, trebuie să adaug o altă axă Y la diagrama cu spline dinamice. Cu scriptul simplu de mai jos puteți adăuga a doua axa y foarte ușor.
