v1.4.49

🎉 1.4.49

✨ Features added-

1. Added the prop renderDataPointsAfterAnimationEnds to Line/Area charts to render the data points after the animation has ended. This flag can be helpful if onPress does not work in case of multi-line animated charts. See #921

🐛 Bug fixes

1. Fixed the issue- "getPointerProps starts from 0 index, regardless of where you press and drag on the LineChart". See #937
2. Fixed the issue- "Unable to use multi onPress in LineChart". See #921 and #570
3. Fixed the issue- "LineChart 1st data point does not show pointer label if initialSpacing={0}". See #925

🔨 Refactor

Made the value property of data items optional for Bar and Line/Area charts. Added null safety types for internal calculations, while the <BarChart> and <LineChart> components exposed by the library will be capable of accepting null/undefined values as data items, internally it will be conerted to respective nullSafe type after handling the null values (by interpolatio or replacing with 0).
Below are the exposed types and their corresponding null afe types-

Chart Type	Type of data prop	Corresponding null safe type
BarChart	barDataItem[]	barDataItemNullSafe[]
LineChart	lineDataItem[]	lineDataItemNullSafe[]
LineChart with dataSet	DataSet[]	DataSetNullSafe[]

This refactor fixes the below type-related issues-

1. #787
2. #781

v1.4.48

🎉 1.4.48 Major Release

✨ Features added-

1. Added support for barMarginBottom to stacked bar charts. See #126 (comment)
2. Added the prop customBackground to Bar, Line, Area charts. customBackground is an object with following keys (All of which are optional). See #790

CustomBackground

type CustomBackground = {
  color?: ColorValue
  component?: Function
  horizontalShift?: number
  verticalShift?: number
  height?: number
  width?: number
  widthAdjustment?: number
}

3. Added the props- focusTogether and focusProximity to Line and Area charts to control the focus behaviour. See #910
4. BarChart lineConfig with strokeDashArray support. See #927
5. Added the property resetPointerIndexOnRelease inside pointerConfig to set pointerIndex to -1 upon releasing the pointer. Default value is false. See #854
6. Added the property activatePointersInstantlyOnTouch inside pointerConfig whose default value is true. When set to false, the pointer will be activated not instantly after touch, but on dragging after touch. See #934

2. Fixed issue with X-axis label position in stacked bar charts with negative values.
3. Some fix about vertical lines in Line charts.

v1.4.47

🎉 1.4.47

✨ Features added-

1. Added the properties hidePointerForMissingValues and hidePointerDataPointForMissingValues to the PointerConfig object. In case there are data items with missing/undefined/null values the library interpolates those values. But if you don't want the pointer to be displayed for such values, you can set the hidePointerForMissingValues property to true. Its default value is false. When hidePointerForMissingValues is set to true, hidePointerDataPointForMissingValues automatically becomes true, unless otherwise specified. See #881

🐛 Bug fixes

1. The vertical strips shown by using the showStrip property were always shown over the data points, but now they will be shown beneath the data points. This behaviour can be reversed by using the stripOverDataPoints prop.

v1.4.46

🎉 1.4.46

Added the prop named stripOverDataPoints to Line charts. If set true, the vertical strip appears over the data points, else it appears beneath the data points. See #877

v1.4.45

🎉 1.4.45

✨ Features added-

1. Added the property horizontalStripConfig inside the pointerConfig to create crosshair effect.

🐛 Bug fixes

1. Fixed the issue- "PieChart is not displayed if there is a huge difference between several values". See #874
2. Fixed the issue- "App crashes when extrapolateMissingValue is set to false and only the last value is defined". See #871
3. Fixed the issue- Population pyramid chart with a mid axis has misaligned X-axis labels.
4. Fixed the issue- Line chart's line is misaligned if dataPointsRadius is large.

v1.4.44

🎉 1.4.44

✨ Features added-

1. Added support for different spacing for each line in Line/Area charts. Added the props spacing1, spacing2, spacing3... See #858
2. Added support for different spacing for each data point in a line in Line/Area charts. Added the spacing property inside the objects of the data and dataSet arrays.
3. Added the tooltip feature in Pie/Donut charts using the showTooltip prop.

🐛 Bug fixes

1. Fixed the issue- "yAxisOffset does not work with stackData". See #862
2. Fixed the issue- zIndex not working for Lines/Curves of the Line/Area charts.
3. Used scrollAnimation when scrolling to a given index using the scrollToIndex prop. See #859

1. Added 185 screenshot tests to avoid regressions and make the library pixel perfect. See https://abhinandan-kushwaha.github.io/TestingCharts/ss-test/test.html

v1.4.41

🎉 1.4.41

Fixed the x-axis alignment issue for animated gradient Bar charts when using xAxisLabelsVerticalShift. Also fixed the extra space at the bottom when using xAxisLabelsVerticalShift.

See #842

v1.4.40

🎉 1.4.40

✨ Features added-

Added the properties dynamicLegendComponent and dynamicLegendContainerStyle inside the pointerConfig object.

dynamicLegendComponent is a property inside the pointerConfig prop, very similar to pointerLabelComponent, the only difference is that it is stationary whereas pointerLabelComponent moves as the pointer moves. You can set the position of the dynamicLegendComponent using the dynamicLegendContainerStyle property inside pointerConfig

You are supposed to assign a callback function to dynamicLegendComponent. The callback function receives 2 parameters-

1. Array of currently selected items (in case you are rendering a single line, the array will have a single item)
2. Index of the selected item.
   Note: The legend component appears only as long as the pointer remains remains on the screen. To make the dynamic legend remain persistently on the screen, you can set the persistPointer property to true. The initialPointerIndex property can also be useful.

🐛 Bug fixes

1. Fixed the issue- autoShiftLabels not working properly. See https://gifted-charts.web.app/barchart/#xAxisShift

2. Fixed the issue- "Bar alignment issue when using the labelsExtraHeight prop." See #839
