## 0.45.1
* **IMPORTANT** **Fuck Vladimir Putin**
* **BUGFIX** Fix `FlSpot.nullSpot` at the first of list bug, #912.
* **FEATURE** Add `scatterLabelSettings` property in [ScatterChart](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/scatter_chart.md) which lets you to add titles on the spots, #902.

## 0.45.0
* **BUGFIX** Fix `clipData` implementation in ScatterChart and LineChart, #897.
* **BUGFIX** Fix PieChart changing sections issue (we have disabled semantics for pieChart badgeWidgets), #861.
* **BUGFIX** Fix LineChart width smaller width or height lower than 40, #869, #857.
* **BUGFIX** Allow to show title when axis diff is zero, #842, #879.
* **IMPROVEMENT** Improve iteration over axis values logic (it solves some minor problems on showing titles when min, max values are below than 1.0).
* **IMPROVEMENT** Add `baselineX` and `baselineY` property in our axis-based charts, It fixes a problem about `interval` which mentioned in #893 (check [this sample](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md#gist---baselinex-baseliney-sample-source-code).
* **IMPROVEMENT** Added `distanceCalculator` to `LineTouchData` which is used to calculate the distance between spots and touch events, #716, #261, #892
* **BREAKING** `LineTouchResponse` response now contains a list of `TouchLineBarSpot` instead of `LineBarSpot`. They are ordered based on their distance to the touch event and also contain that distance.

## 0.41.0
* **BUGFIX** Fix getNearestTouchedSpot. Previously it returned the first occurrence of a spot within the threshold, and not the nearest, #641, #645.
* **FEATURE** Add `textAlign` property in the [SideTitles](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#sidetitles), #784.
* **IMPROVEMENT** Write some unit-tests and enable code coverage reports in our CI

## 0.40.6

* **IMPROVEMENT** Fix interval below one, #811

## 0.40.2
* **IMPROVEMENT** Use 80 characters for code format line-length instead of 100 (because pub.dev works with 80 and decreased our score). 

## 0.40.1
* **IMPROVEMENT** Fix pub.dev determining web support, #780.
* **IMPROVEMENT** Implement flutter_lints in the code.
* **BUGFIX** Fix below/above area data transparency issue, #770.

## 0.40.0
* **BUGFIX** Fixed pieChart `centerRadius = double.infinity` problem, #747.c
* **BREAKING** Charts touchCallback signature has changed to `(FlTouchEvent event, BaseTouchResponse? response)` which [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) determines which touch/pointer event happened (such as `FlTapUpEvent`, `FlPanUpdateEvent`, ...), and BaseTouchResponse gives us the chart response.
* **BREAKING** Chart touchResponse classes don't have `touchInput` and `clickHappened` properties anymore. Use [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) provided in the callback instead of `touchInput`. Check `event is FlTapUpEvent` to detect touch events instead of checking `clickHappened`;
* **IMPROVEMENT** Again we support `longPress` touch events. check [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) to see all kind of supported touch/pointer events (which can be `FlLongPressStart`, `FlLongPressMoveUpdate`, `FlLongPressEnd`, ...). Also you can check out [touch handling doc](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/handle_touches.md), #649.
* **IMPROVEMENT** Added `mouseCursorResolver` callback in touchData classes such as [LineTouchData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md#linetouchdata-read-about-touch-handling) and [BarTouchData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#bartouchdata-read-about-touch-handling). You can change the [MouseCursor](https://api.flutter.dev/flutter/services/MouseCursor-class.html) based on the provided [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) and touchResponse using this callback. (We have used this feature in [PieChartSample2](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/scatter_chart.md#sample-2-source-code))
* **BUGFIX** Fixed `ScatterChart` default touchHandling crash
* **BUGFIX** Fix text styles when updating the theme. Check this [theme-aware-sample](https://gist.github.com/imaNNeoFighT/bf95e720621d799ab980a7a3287c56e2).
* **IMPROVEMENT** Show narrow horizontal and vertical grid lines by default.
* **IMPROVEMENT** Show all left, top (except BarChart), right, bottom titles in Axis based charts by default.
* **IMPROVEMENT** Set `BarChartAlignment.spaceEvenly` as `alignment` property of [BarChartData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#barchartdata) by default
* **IMPROVEMENT** Allow [BarChart](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md) and [LineChart](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md) have empty values instead of throwing exception (we don't show anything if there is nothing provided)
* **BREAKING** `textStyle` of [ScatterTooltipItem](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/scatter_chart.md#ScatterTooltipItem) is now nullable and optional. `bottomMargin` is also optional (default is zero). So both are named parameters now.
* **IMPROVEMENT** We improved touch precision of `ScatterChart`.
* **BUGFIX** Fix overlapping last gridlines on border lines problem.
* **NEWS** Your donation **motivates** me to work more on the `fl_chart` and resolve more issues. Now you can [buy me a coffee](https://www.buymeacoffee.com/fl_chart)!

## 0.36.4
* **IMPROVEMENT** Added `borderSide` property in [BarChartRodData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#BarChartRodData) and [BarChartRodStackItem](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#BarChartRodStackItem) to draw strokes around each bar and rod stack items, #714.

* **IMPROVEMENT** Added `borderSide` property in [PieChartSectionData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/pie_chart.md#piechartsectiondata) to draw strokes around each section, #606.

## 0.36.2
* **IMPROVEMENT** Support `onMouseExit` event in all charts.
* **IMPROVEMENT** Add `rotateAngle` property in [LineTouchTooltipData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md#linetouchtooltipdata), [BarTouchTooltipData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#bartouchtooltipdata), [ScatterTouchTooltipData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/scatter_chart.md#scattertouchtooltipdata), #260, #679.

## 0.35.0
* **IMPROVEMENT** Added `children` property in the [LineTooltipItem](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md#linetooltipitem), [BarTooltipItem](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#bartooltipitem) and [ScatterTooltipItem](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/scatter_chart.md#scattertooltipitem) which accepts a list of [TextSpan](https://api.flutter.dev/flutter/painting/TextSpan-class.html). It allows you to have more customized texts inside the tooltip. See [BarChartSample1](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#sample-1-source-code) and [ScatterSample2](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/scatter_chart.md#sample-2-source-code), #72, #294.
