how to create y-axis slider on canvas js on mouse slide

[Adithya Menon]

@samrat,

Adding scroller to y-axis is not available as a built-in feature as of now. However, you can place JQuery UI slider vertically to achieve the same as shown in the code-snippet below,

$("#slider").slider({
  range: true,
  orientation: "vertical",
  min: chart.axisY[0].get("minimum"),
  max: chart.axisY[0].get("maximum"),
  values: [ 50, 100 ], //Default zoom state
  slide: function( event, ui ) {
      chart.axisY[0].set("viewportMinimum", ui.values[0], false);
    chart.axisY[0].set("viewportMaximum", ui.values[1]);    
  }
});

Please take a look at this JSFiddle for an example along with complete code.
