Chartwerk Pod

Plugin with an abstract class providing basics for visualization.

Plugin renders:

• SVG container with:
  • Axes, with ticks and labels.
  • Grid, which scales using specified time interval.
  • Legend, which can hide metrics.

Options:

Options are not mandatory:

• margin — chart container positioning;

margin={
  top: number,
  right: number,
  bottom: number,
  left: number
}

• colors: array of metrics colors (should be equal or greater than series length);

['red', 'blue', 'green']

• timeInterval: interval in minutes (max value = 60) affecting grid and x-axis ticks.

• tickFormat: config to control the axes ticks format.

{
  xAxis: string; // x-axis time format (see [d3-time-format](https://github.com/d3/d3-time-format#locale_format) } 
  xTickOrientation: TickOrientation; // horizontal, diagonal or vertical orientation
}

for example:

{
  xAxis: '%Y-%m-%d %H:%M',
  xTickOrientation: TickOrientation.DIAGONAL
}

• labelFormat: labels for axes.

{
  xAxis: string;
  yAxis: string;
}

for example:

{
  xAxis: 'Time';
  yAxis: 'Value';
}

• bounds: specify which metrics should be rendered as confidence. (TODO: move to @chartwerk/line-chart) $__metric_name macro can be used here. It will be replaced with each metric's name to find it's bound.

{
  upper: string;
  lower: string;
}

for example: metric names: 'serie', 'serie upper_bound', 'serie lower_bound'

bounds={
  upper: '$__metric_name upper_bound';
  lower: '$__metric_name lower_bound';
}

'serie upper_bound', 'serie lower_bound' metrics will be rendered as serie metric confidence;

• timeRange: time range in timestamps

{
  from: number;
  to: number;
}

for example:

{
  from: 1582770000000;
  to: 1582810000000;
}

• eventsCallbacks: event callbacks

{
  zoomIn: (range: [number, number]) => void,
  zoomOut: (center: number) => void,
  mouseMove: (evt: any) => void,
  mouseOut: () => void,
  onLegendClick: (idx: number) => void
}
