Values are customized by replacing the value with a dictionary containing the value as 'value':
chart = pygal.Line()
chart.add([1, {'value': 2, 'label': 'two'}, 3])
chart.add([3, 2, 1])You can add per value metadata like labels, by specifying a dictionary instead of a value:
chart = pygal.Bar() chart.add('First', [{'value': 2, 'label': 'This is the first'}]) chart.add('Second', [{'value': 4, 'label': 'This is the second'}]) chart.add('Third', 7) chart.add('Fourth', [{'value': 5}]) chart.add('Fifth', [{'value': 3, 'label': 'This is the fifth'}])
You can force the color of a value by specifying a color key:
chart = pygal.Bar() chart.add('Serie', [ {'value': 2}, 3, 4, {'value': 10, 'color': 'red'}, {'value': 11, 'color': 'rgba(255, 45, 20, .6)'}, 4, 2 ])
The color key set the fill and the stroke style. You can also set the css style manually:
chart = pygal.Bar() chart.add('Serie', [ {'value': 2}, 3, 4, {'value': 10, 'style': 'fill: red; stroke: black; stroke-width: 4'}, {'value': 11, 'style': 'fill: rgba(255, 45, 20, .6); stroke: black; stroke-dasharray: 15, 10, 5, 10, 15'}, 4, 2 ])
It is possible to pass svg attribute to the node representing value.
chart = pygal.Line() chart.add('Serie', [ {'value': 1, 'node': {'r': 2}}, {'value': 2, 'node': {'r': 4}}, {'value': 3, 'node': {'r': 6}}, {'value': 4, 'node': {'r': 8}} ])
You can also add hyper links:
chart = pygal.Bar() chart.add('First', [{ 'value': 2, 'label': 'This is the first', 'xlink': 'http://en.wikipedia.org/wiki/First'}])
- chart.add('Second', [{
'value': 4, 'label': 'This is the second', 'xlink': 'http://en.wikipedia.org/wiki/Second'}])
chart.add('Third', 7)
- chart.add('Fourth', [{
'value': 5, 'xlink': 'http://en.wikipedia.org/wiki/Fourth'}])
- chart.add('Fifth', [{
'value': 3, 'label': 'This is the fifth', 'xlink': 'http://en.wikipedia.org/wiki/Fifth'}])
You can specify a dictionary to xlink with all links attributes:
chart = pygal.Bar() chart.add('First', [{ 'value': 2, 'label': 'This is the first', 'xlink': {'href': 'http://en.wikipedia.org/wiki/First'}}])
- chart.add('Second', [{
'value': 4, 'label': 'This is the second', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Second', 'target': '_top'} }])
chart.add('Third', 7)
- chart.add('Fourth', [{
'value': 5, 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Fourth', 'target': '_blank'} }])
- chart.add('Fifth', [{
'value': 3, 'label': 'This is the fifth', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Fifth', 'target': '_self'} }])
Finally legends can be link with the same mechanism:
chart = pygal.Bar() chart.add({ 'title': 'First', 'tooltip': 'It is the first actually', 'xlink': {'href': 'http://en.wikipedia.org/wiki/First'} }, [{ 'value': 2, 'label': 'This is the first', 'xlink': {'href': 'http://en.wikipedia.org/wiki/First'} }])
- chart.add({
'title': 'Second', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Second', 'target': '_top' }
- }, [{
'value': 4, 'label': 'This is the second', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Second', 'target': '_top'}
}])
chart.add('Third', 7)
- chart.add({
'title': 'Fourth', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Fourth', 'target': '_blank' }
- }, [{
'value': 5, 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Fourth', 'target': '_blank'}
}])
- chart.add({
'title': 'Fifth', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Fifth', 'target': '_self' }
- }, [{
'value': 3, 'label': 'This is the fifth', 'xlink': { 'href': 'http://en.wikipedia.org/wiki/Fifth', 'target': '_self'}
}])
