43 | 44 | ## How to use 45 | - The usage of this library is perfectly consistent with that of [MPAndroidChart](https://github.com/PhilJay/MPAndroidChart) 46 | - Please read [official document](https://weeklycoding.com/mpandroidchart-documentation/) 47 | - A detailed explanation can be understood immediately by looking at the code of the sample project. 48 | 49 | ## RangeBarEntry 50 | - min 51 | - max 52 | 53 | ## Setup Chart 54 | ```kotlin 55 | private fun RangeBarChart.setup() { 56 | setScaleEnabled(false) 57 | setDrawGridBackground(false) 58 | setBackgroundColor(Color.TRANSPARENT) 59 | description.isEnabled = false 60 | xAxis.apply { 61 | position = XAxis.XAxisPosition.BOTTOM 62 | setDrawGridLines(false) 63 | } 64 | axisLeft.apply { 65 | setDrawGridLines(false) 66 | axisMinimum = -20f 67 | axisMaximum = 40f 68 | } 69 | axisRight.isEnabled = false 70 | legend.isEnabled = false 71 | data = RangeBarData(createSet()) 72 | } 73 | ``` 74 | 75 | ## Create DataSet 76 | ```kotlin 77 | RangeBarDataSet(null, "RangeBar").apply { 78 | color = Color.parseColor("#2BDD9E") 79 | barWidth = 0.4f 80 | isHighlightEnabled = true 81 | highLightColor = Color.CYAN 82 | minColor = Color.parseColor("#22BCFE") 83 | maxColor = Color.parseColor("#FC351E") 84 | setDrawValues(false) 85 | valueTextSize = 12f 86 | valueFormatter = object : ValueFormatter() { 87 | override fun getFormattedValue(value: Float): String = "${value.toInt()}°C" 88 | } 89 | } 90 | ``` 91 | ## Add your entries 92 | ```kotlin 93 | private fun getWeatherEntries(): List { 94 | val values = mutableListOf() 95 | values.add(RangeBarEntry(1f, -7f, 1f)) 96 | values.add(RangeBarEntry(2f, -4f, 4f)) 97 | values.add(RangeBarEntry(3f, 2f, 11f)) 98 | values.add(RangeBarEntry(4f, 8f, 18f)) 99 | values.add(RangeBarEntry(5f, 14f, 23f)) 100 | values.add(RangeBarEntry(6f, 19f, 26f)) 101 | values.add(RangeBarEntry(7f, 23f, 28f)) 102 | values.add(RangeBarEntry(8f, 25f, 33f)) 103 | values.add(RangeBarEntry(9f, 17f, 25f)) 104 | values.add(RangeBarEntry(10f, 10f, 18f)) 105 | values.add(RangeBarEntry(11f, 3f, 11f)) 106 | values.add(RangeBarEntry(12f, -3f, 4f)) 107 | return values 108 | } 109 | ``` 110 | ```kotlin 111 | private fun RangeBarChart.addData() { 112 | val data = data ?: return 113 | val rangeBarDataSet = data.getDataSetByIndex(0) ?: return 114 | val values = getWeatherEntries() 115 | rangeBarDataSet.values = values 116 | data.notifyDataChanged() 117 | notifyDataSetChanged() 118 | } 119 | ``` 120 | 121 |

122 | 123 | 124 | ## Customize 125 | ### RangeBarDataSet 126 | 127 | | variable | Description | 128 | | ----------------------- | ---------------- | 129 | | `barWidth` | Adjust board width | 130 | | `minColor` | Min color int | 131 | | `maxColor` | Max color int | 132 | 133 | ## FAQ 134 | 135 | ### Can I use BarChart's function/variable? 136 | - Yes, RangeBarChart is a class implemented by inheriting from BarChart. 137 | - So you can use all the features that BarChart uses. 138 | 139 | 140 | ### How is it different from candlestick charts? 141 | - Candle charts must specify a starting and ending point as well as a minimum and maximum. 142 | - It is used for the purpose of using stock charts, not to display only the range we want. 143 | - RangeBarChart only shows the minimum and maximum ranges. 144 | 145 |
