You can set `xError` and `yError` in the [FlSpot](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/base_chart.md#flspot) or `toYErrorRange` in [BarChartRodData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartroddata). Also we have `errorIndicatorData` property in our [LineChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md#linechartdata), [BarChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md#barchartdata) and [ScatterChartData](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#scatterchartdata) that is responsible to render the error bars. You can take a look at the [LineChartSample 13](https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/line/line_chart_sample13.dart) and [BarChartSample 8](https://github.com/imaNNeo/fl_chart/blob/main/example/lib/presentation/samples/bar/bar_chart_sample8.dart) in our [sample app](https://app.flchart.dev), #1483 + +## 0.70.1 +* **FEATURE** (by @Peetee06) Add `panEnabled` and `scaleEnabled` properties in the TransformationController, #1818 +* **FEATURE** (by @mitulagr2) Add `renderPriority` feature in our [ScatterSpot](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md#scatterspot), #1545 +* **FEATURE** (by @imaNNeo) Add `rotationQuarterTurns` property in our Axis-Based charts (such as [LineChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/line_chart.md), [BarChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/bar_chart.md) and [ScatterChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/scatter_chart.md)). It allows you to rotate the chart 90 degrees (clockwise) in each turn. For example you can have Horizontal Bar Charts by setting `rotationQuarterTurns` to 1 (which rotates the chart 90 degrees clockwise). It works exactly like [RotatesBox](https://api.flutter.dev/flutter/widgets/RotatedBox-class.html) widget, #113 +* **FEATURE** (by @soraef) Add `isMinValueAtCenter` property in the [RadarChart](https://github.com/imaNNeo/fl_chart/blob/main/repo_files/documentations/radar_chart.md) to allow the user to set the minimum value at the center of the chart, #1351, #1442 + +## 0.70.0 +* **FEATURE** (by @Peetee06) Implemented a 5 years-old feature request about scroll and zoom support in our axis-based charts.

But it caused some memory issues, as we don't have a quick solution for this, we disabled the caching logic for now, later we can move the calculation logic to the render objects to keep and update them only when the data is changed, #1106, #1693 +* **BUGFIX** (by @imaNNeo) Fix showing grid lines even when there is no line to show in the LineChart, #1691 +* **IMPROVEMENT** (by @sczesla) Allow

This helps us and the +community to discuss the issue and choose what is deemed to be the +best solution. + +### Mention the related issues: +If you are going to fix or improve something, please find and mention the related issues in commit message and Pull Request description. +In case you couldn't find any issue, it's better to create an issue to explain what's the issue that you are going to fix. + +## Let's start by our drawing architecture +We have a *_chart_painter.dart class per each chart type.
