desired-output

i have referred c3.js examples guide attempts: c3js.org/samples/axes_y2.html , c3js.org/samples/axes_x_tick_values.html able produce mixed line , bar chart 2 y-axes. when add in labels x-axis, however, lose second y axis:

i can chart show 2 y-axes:

... once try add labels x-axis, second y axis disappears:

am doing wrong, or limitation of c3.js? in advance sharing knowledge , insights!

just trivial syntax error you'll kick ;-)

you've declared axis twice in configuration above

instead, put x axis declaration in axis property alongside y axes

axis: {           y: {             label: {               text: 'open cases',               position: 'outer-middle'             }           },           y2: {             show: true,             label: {               text: 'total budget',               position: 'outer-middle'             }           }         },         x: {             type: 'timeseries',             tick: {                     values: [2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017]                 },         }     }
