🎉 1.4.9

✨ Features added-

  1. Added support for multiple lines corresponding to secondary y-axis. Now we can add the property isSecondary inside the objects of the dataSet array. When using isSecondary, make sure to pass the secondaryYAxis prop. See Abhinandan-Kushwaha#586

  2. Added support for ring Pie charts. Just pass the prop ring in the <PieChartPro> component to make a ring like Pie chart. See Abhinandan-Kushwaha#584

  3. Added support for pieInnerComponent to <PieChartPro>

🎉 1.4.8 Mega Release ⭐️

✨ Features added-

Animation in Pie and donut charts using the <PieChartPro> component. See Abhinandan-Kushwaha#555

Curved paths (border-radius) in donut sections supported using the <PieChartPro> component. See Abhinandan-Kushwaha#554

Support for expo gradient, thanks to onyx-flame for his PR Abhinandan-Kushwaha#571

🐛 Bug fixes

  1. refactors and adjustments related to xAxisThickness and yAxisOffset. See Abhinandan-Kushwaha#574

🎉 1.4.7

🐛 Bug fixes

  1. Fixed the issue - animateOnDataChange skipping the initial render, thus rendering an empty chart. See Abhinandan-Kushwaha#537
  2. Fixed the issue - yAxisOffset not working with dataSet in Line (and Area) charts.

🎉 1.4.6

✨ Features added-

  1. Added the properties shiftTextBackgroundX and shiftTextBackgroundY to data items of Pie (and donut) charts. If we pass shiftTextX, the background will also shift (because the library assigns a default value of shiftTextBackgroundX = shiftTextX). This can be overridden by manually passing shiftTextBackgroundX. Same applies to shiftTextBackgroundY

🐛 Bug fixes

  1. Fixed the issue- "shiftTextX not working to focused section of the Pie (and donut) charts" Thanks to YASH-TRONX for his PR Abhinandan-Kushwaha#534
  2. Fixed the issue- line inside Bar (combined chart) getting cropped from right side in case of secondary See Abhinandan-Kushwaha#532 This actually got fixed in the core library (version 0.0.16). Here I just had to use the latest version of gifted-charts-core

🎉 1.4.5

✨ Features added-

  1. Added the prop onScroll to Bar, Stacked Bar, Line and Area charts. It is a callback function that takes event as a parameter.
  2. Added the props paddingHorizontal and paddingVertical to Pie (and Donut) charts. This will be useful to accomodate "onBorder" labels. See Abhinandan-Kushwaha#528

🐛 Bug fixes

Fixed issue with barInnerComponent for Bar charts that don't have gradient. See Abhinandan-Kushwaha#500 (comment)

🎉 1.4.4

✨ Features added-

Added the prop onPressOut to Bar and Stacked Bar charts. See Abhinandan-Kushwaha#523

🐛 Bug fixes

Fixed issue with noOfSectionsBelowXAxis not taking the value 0 for Line charts. See Abhinandan-Kushwaha#526

🎉 1.4.3

✨ Features added-

  1. Added interpolation to Line charts. These props can be used to control interpolation- interpolateMissingValues, showDataPointsForMissingValues and onlyPositive. See Interpolation in Line chart docs
  2. Added BEFORE_DATA_POINT to EdgePosition enum for step charts, and renamed the AT_DATA_POINT EdgePosition to AFTER_DATA_POINT. The default EdgePosition is AFTER_DATA_POINT.

🐛 Bug fixes

  1. Fixed the issue- "topLabelComponent not visible for bar charts". See Abhinandan-Kushwaha#519
  2. Fixed RTL issue in pagination. Thanks to Houssem-Eddine Kellou for his PR Abhinandan-Kushwaha/gifted-charts-core#3

🎉 1.4.2

✨ Features added-

Added the props focusBarOnPress and focusedBarConfig to Bar charts. Using these, we can focus or highlight a bar on press. See Abhinandan-Kushwaha#512

🐛 Bug fixes

  1. Fixed issues with stepValue, noOfSections and maxValue. See Abhinandan-Kushwaha#511
  2. Fixed issue with pagination, (isCloseToStart not returning true) PR Abhinandan-Kushwaha/gifted-charts-core#2 by Houssem-Eddine Kellou

🔨 Refactor

Moved gifted-charts-core to dependency and put the 3rd party libraries into devDependency. PR Abhinandan-Kushwaha#514 by Armon Raphiel

🎉 1.4.1

Exported ruleTypes which was missed in version 1.4.0

🎉 1.4.0 Mega Release ⭐️

📣 This release contains a huge refactor. 🔨 We have now moved most of the logic and maths (including utils, constatnts and types) to our newly launched library named gifted-charts-core

This helped in-

  1. Segragating UI and logic
  2. Modularity and code re-usability
  3. We are very soon going to launch a library for web named react-gifted-charts❤️ With this we will be able to render charts in react using exactly the same code we use in react-native-gifted-charts!

This huge refactor might have introduced some bugs. Please bear with us.🙏
To avoid this in future mega releases, I am going to add thorough tests in the next release.

We will soon release version 2.0 after adding all types and unit tests for each component!!

✨ Features added-

  1. Added support for Pagination using the props onEndReached, onStartReached and endReachedOffset. Thanks to Houssem-Eddine Kellou who added this feature through his PR- Abhinandan-Kushwaha#504. Pagination is now supported for Bar, Stack, Line and Area charts!

  2. Added the prop onLongPress to Bar and Stacked Bar charts. See Abhinandan-Kushwaha#506

🎉 1.3.33

✨ Features added-

  1. Added the prop barInnerComponent to Bar and Stacked Bar charts. barInnerComponent can also be passed as a property inside the data items. See Abhinandan-Kushwaha#500

  2. Added the prop pieInnerComponent to Pie and Donut charts. pieInnerComponent can also be passed as a property inside the data items. See Abhinandan-Kushwaha#500

  3. Exported the following types from react-native-gifted-charts-

  • barDataItem
  • stackDataItem
  • BarChartPropsType
  • StackedBarChartPropsType
  • pieDataItem
  • PieChartPropsType
  • lineDataItem
  • bicolorLineDataItem
  • LineChartPropsType
  • LineChartBicolorPropsType

  • PopulationPyramidPropsType

🔨 Refactor

  1. Moved types to '.\types.ts files for each type of chart and gave proper names to types.

🎉 1.3.32

🐛 Minor bug fixes with initialSpacing for Line inside Bar charts (combined Bar and Line charts).

🎉 1.3.31

🐛 Bug fixes

  1. Fixed issue with onPress not working on elements just above the chart. See Abhinandan-Kushwaha#497
    It was an issue with the of the chart overflowing and overlapping in case stepHeight was large.

  2. Fixed the issue- showStripOnFocus: height of strip becomes smaller when using overflowTop.

🎉 1.3.30

🐛 Bug fixes

  1. Fixed issue with pointerEvent value: box-none in Pie charts. See Abhinandan-Kushwaha#491 and Abhinandan-Kushwaha#472
  2. Fixed issue with data3 and data4 in Line charts. See Abhinandan-Kushwaha#490
  3. Fixed issue- strip not visible for Line and Area charts having pointerConfig with pointerLabelComponent.

🎉 1.3.29 Major release

✨ Features added-

  1. Added support for Population Pyramid charts!! See Population Pyramid props
  2. Pointer labels will now be rendered on top of the rest of the chart content. Earlier, reference lines sometimes used to appear over the pointer lables, this has been fixed now.
  3. Added the prop referenceLinesOverChartContent for Bar charts.

🐛 Bug fixes

  1. Fixed the issue- LineChart having a single data item and using the prop adjustToWidth caused crashes. See Abhinandan-Kushwaha#484
  2. Fixed issue with data point label getting cropperd. See Abhinandan-Kushwaha#486
  3. Fixed the issue- Reference line overlapping the tooltip. See Abhinandan-Kushwaha#476

🎉 1.3.28

🐛 Minor bug fixes with pointerEvents in Pie charts and yAxisExtraHeight with pointerLabelComponent in Bar and Line charts. See Abhinandan-Kushwaha#472 and Abhinandan-Kushwaha#467 (comment)

🎉 1.3.27

✨ Features added-

  1. Added support for mix of positive + negative values in Stacked Bar charts. Thanks to Christoph who added this feature through his PR- Abhinandan-Kushwaha#470
  2. Added the prop yAxisExtraHeight for extra length of Y axis at the top. Default value is 1/20th of the chart height.
  3. Added the prop inwardExtraLengthForFocused. This allows us to render donut charts whose focused section grows inwards. See Abhinandan-Kushwaha#325

🐛 Bug fixes

  1. Earlier, charts used to have an extra length of Y axis equal to sectionHeight/2 at the top. Due to this, charts' height used to change along with sectionHeight. Fixed this by making the default value of yAxisExtraHeight to a constant value which equals 1/20th of the chart height. See Abhinandan-Kushwaha#467
  2. Fixed the issue with getPointerProps which threw a warning - Cannot update a component (xxx) while rendering a different component (yyy). See facebook/react#22633

🎉 1.3.26

  2. Added barBorderWidth and barBorderColor to Bar charts.

  3. Added separate spacing for Line charts inside BarCharts. The line rendered in a Bar chart can have its own spacing value independent from the spacing of the bars. It can be set using the spacing property in the lineConfig object.

  4. Added these props to apply border radius to Stacked Bar charts-

  • stackBorderRadius
  • stackBorderTopLeftRadius
  • stackBorderTopRightRadius
  • stackBorderBottomLeftRadius
  • stackBorderBottomRightRadius

  2. Added the prop highlightedRange to render the parts of lines lying in a given data range with a different style (color, thickness,type). See https://stackoverflow.com/questions/70406903/different-colors-line-chart-with-react-native-chart-kit

type HighlightedRange = {
  from: number;
  to: number;
  color?: string | ColorValue;
  thickness?: number;
  strokeDashArray?: Array<number>;
};
  1. Added the property pointerEvents to the pointerConfig object. If you have a Pressable / Touchable item in your pointerLabelComponent, then you should set pointerEvents to 'auto' inside the pointerConfig object. See Abhinandan-Kushwaha#447

🐛 Bug fixes

  1. Fixed the issue - Unwanted Spacing below the charts.See Abhinandan-Kushwaha#448

Versions 1.3.20 and 1.3.21 and 1.3.22 were mistakes and reverts...

🎉 1.3.19

✨ Features added-

  1. Added support for dynamic number of lines with the help of the dataSet prop. We can now pass an array of data instead of using data, data2, data3 etc.
  2. Added property formatYLabel to the secondaryYAxis, so we can now format the labels of the secondary Y-Axis using formatYLabel. See Abhinandan-Kushwaha#442

🎉 1.3.17

✨ Features added-

  1. Added support for Step charts. To render a step chart, just pass the prop stepChart to the <LineChart> component.
    See Abhinandan-Kushwaha#438

  2. Added the properties- initialPointerIndex, initialPointerAppearDelay, and persistPointer to the pointerConfig object. See Abhinandan-Kushwaha#427

  3. Added support for customizing individual / specific rules in charts using the prop rulesConfigArray. See Abhinandan-Kushwaha#432 (comment)

  4. Added 2 new props- xAxisLabelsHeight and xAxisLabelsVerticalShift. Here's a brief description of the use case of these props-

The height of X axis labels container is computed automatically. Sometimes you may need to explicitly provide the height of X-axis labels container. An example case is when the font size of label texts is large. Use the `xAxisLabelsHeight`` prop if the labels appear cropped from bottom.

Note- Using the xAxisLabelsHeight prop may shift the X axis labels up or down, making the label text overlap with the chart content. In such a case you can use the `xAxisLabelsVerticalShift`` prop to adjust the vertical position of X axis labels.

See Abhinandan-Kushwaha#433

🐛 Bug fixes

  1. Fixed issue- Pie charts get distorted when one value is non-zero and rest values are zero. See Abhinandan-Kushwaha#436

lineGradientEndColor?: string;

See https://github.com/Abhinandan-Kushwaha/react-native-gifted-charts/blob/master/docs/LineChart/LineChartProps.md#line-related-props

  1. Added support for custom gradient in area charts using the props areaGradientComponent and areaGradientId

🐛 Bug fixes

🎉 1.3.13

✨ Features added-

  1. Added the formatYLabel prop. The user can now pass a callback function that takes the label generated by the library and modifies it. The modified label returned by the callback function will be finally rendered along the Y-axis. See Abhinandan-Kushwaha#22

🐛 Bug fixes

  2. Fixed issue with the position of verticalLines when hideYAxisText is set to true.

🔨 Refactor

  1. replaced JSON.parse(JSON.stringify()) with custom deepClone method (added in utils). It fixed this issue- Abhinandan-Kushwaha#397

🎉 1.3.8

✨ Features added-

  1. Added the property named isSecondary in the lineConfig object see Abhinandan-Kushwaha#392
  2. Replaced the prop verticalLinesType with verticalLinesStrokeDashArray

🐛 Bug fixes

Fixed issue with secondary Y axis position (it was shifting towards right earlier)

🎉 1.3.7

✨ Features added-

  1. Added the prop scrollEventThrottle (only for iOS) see https://reactnative.dev/docs/scrollview#scrolleventthrottle-ios - default value is 0
  2. exposed secondaryDataItem in pointerLabelComponent see Abhinandan-Kushwaha#388

🐛 Bug fixes

Fixed issue with adjustToWidth (Now if you pass the adjustToWidth prop, your chart will take the screen width automatically)

🎉 1.3.6

✨ Features added-

  1. secondary Y axis for charts with negative values
  2. Line chart inside stacked bar chart

🔨 Refactor

minValue is now renamed to mostNegativeValue to avoid confusion

🐛 Bug fixes

  1. Fixed issue with roundToDigits for Y axis labels. Now we add trailing 0s after decimal point if needed. So if the Y axis label is 1.5 and we have roundToDigits={2}, then the label rendered will be 1.50
  2. Fixed Y axis label issue which displayed NaN as a label when we used yAxisOffset and yAxisLabelTexts props together.

🎉 1.3.5

🐛 Minor bug fixes

🎉 1.3.4 Major release

✨ Features added-

1. Y axis on both sides

Added the secondaryYAxis prop to render a secondary Y axis on the right side of the chart. Earliear we were able to render the Y axis either on the left or on the right side, not both.

2. secondaryData and secondaryLineConfig (in Line and Area charts)

In addition to data2, data3, etc, now we have the secondaryData prop. This is done to reference the second line to the secondary Y axis.

3. scrollRef

In Bar, Line and Area charts, we can access the ScrollView using the scrollRef prop. You just need to create a ref using React.useRef() and pass it into the scrollRef prop. The most common use of scrollRef is to scroll to a given position, and to fire the scroll on an event like a button press.

4. scrollToIndex

In Bar, Line and Area charts, we can scroll to any given index using the scrollToIndex prop.

5. RTL horizontal charts

To render a horizontal Bar chart from right to left, pass the rtl prop along with the horizontal prop.

6. curveType and curvature

Now, we support 2 types of curves-

  1. Cubic bezier curve
  2. Quadratic bezier curve

The default curveType is cubiz bezier curve. To change it to quadratic, pass the prop curveType={CurveType.QUADRATIC}

curvature takes a value between 0 and 1. The default curvature value is 0.2
curvature works only for cubic bezier curves. When curvature value is 0, the curve becomes straight line.

7. showValuesAsDataPointsText

In Line and area charts, we can pass the showValuesAsDataPointsText prop to display the value of the data points.

8. Animation in stacked Bar chart

The isAnimated prop is now supported in stacked bar charts.

9. endSpacing

Similar to the initialSpacing we now have a prop named endSpacing as well.

10. overflowBottom

Similar to the overflowTop we now have a prop named overflowBottom as well, but it makes sense only for line and area charts. It gives extra space at the bottom of the chart to make room for dataPoints or dataPointText.

🐛 Fixes

1. Support for expo ❤️

The library used to break when used in an expo project. This was perhaps due to version conflicts in react-native-svg. We have now moved both react-native-svg and react-native-linear-gradient to peer dependencies. This should hopefully fix the issues with expo.

2. Fixed the issue with pointerConfig being jaggy on Android

autoAdjustPointerLabelPosition is now false by default. This should make the Area and Line charts with pointerConfig smooth on Android.
