# 0.6.0
|
||
|
|
* Bars can now be rendered on line charts.
|
||
|
|
* Negative measure values will now be rendered on bar charts as a separate stack from the positive
|
||
|
|
values.
|
||
|
|
* Added a Datum Legend, which displays one entry per value in the first series on the chart. This is
|
||
|
|
useful for pie and scatter plot charts.
|
||
|
|
* The AxisPosition enum in RTLSpec was refactored to AxisDirection to better reflect its effect on
|
||
|
|
swapping the positions of all start and end components, and not just positioning the measure axes.
|
||
|
|
* Added custom colors for line renderer area skirts and confidence intervals. A new "areaColorFn"
|
||
|
|
has been added to Series, and corresponding data to the datum. We could not use the fillColorFn for
|
||
|
|
these elements, because that color is already applied to the internal section of points on line
|
||
|
|
charts (including highlighter behaviors).
|
||
|
|
|
||
|
|
# 0.5.0
|
||
|
|
* SelectionModelConfig's listener parameter has been renamed to "changeListener". This is a breaking
|
||
|
|
change. Please rename any existing uses of the "listener" parameter to "changeListener". This was
|
||
|
|
named in order to add an additional listener "updateListener" that listens to any update requests,
|
||
|
|
regardless if the selection model has changed.
|
||
|
|
* CartesianChart's method getMeasureAxis(String axisId) has been changed to
|
||
|
|
getMeasureAxis({String axisId) so that getting the primary measure axis will not need passing any id
|
||
|
|
that does not match the secondary measure axis id. This affects users implementing custom behaviors
|
||
|
|
using the existing method.
|
||
|
|
|
||
|
|
# 0.4.0
|
||
|
|
* Fixed export file to export ChartsBehavior in the Flutter library instead of the one that resides
|
||
|
|
in charts_common. The charts_common behavior should not be used except internally in the
|
||
|
|
charts_flutter library. This is a breaking change if you are using charts_common behavior.
|
||
|
|
* Declare compatibility with Dart 2.
|
||
|
|
* BasicNumericTickFormatterSpec now takes in a callback instead of NumberFormat as the default
|
||
|
|
constructor. Use named constructor withNumberFormat instead. This is a breaking change.
|
||
|
|
* BarRendererConfig is no longer default of type String, please change current usage to
|
||
|
|
BarRendererConfig<String>. This is a breaking change.
|
||
|
|
* BarTargetLineRendererConfig is no longer default of type String, please change current usage to
|
||
|
|
BarTargetLineRendererConfig<String>. This is a breaking change.
|
||
|
|
|
||
|
|
# 0.3.0
|
||
|
|
* Simplified API by removing the requirement for specifying the datum type when creating a chart.
|
||
|
|
For example, previously to construct a bar chart the syntax was 'new BarChart<MyDatumType>()'.
|
||
|
|
The syntax is now cleaned up to be 'new BarChart()'. Please refer to the
|
||
|
|
[online gallery](https://google.github.io/charts/flutter/gallery.html) for the correct syntax.
|
||
|
|
* Added scatter plot charts
|
||
|
|
* Added tap to hide for legends
|
||
|
|
* Added support for rendering area skirts to line charts
|
||
|
|
* Added support for configurable fill colors to bar charts
|
||
|
|
|
||
|
|
# 0.2.0
|
||
|
|
|
||
|
|
* Update color palette. Please use MaterialPalette instead of QuantumPalette.
|
||
|
|
* Dart2 fixes
|
||
|
|
|
||
|
|
# 0.1.0
|
||
|
|
|
||
