ui.chart

A tool for creating various charts.

The library supports the most common chart types:line, spline, area, bar, pie, donut, scatter, radar. You can customize appearance of a chart through colors, tooltips, templates, scales, labels. It's possible to present multiple data sets on the same chart. Check chart documentation for more detailed description.

Constructor

var chart = webix.ui({
    view:"chart",
    type:"bar",
    value:"#sales#",
    label:"#sales#",
    barWidth:35,
    radius:0,
    gradient:"falling",
