Value Formatting is not done correctly. e00 is added at the last

@PhilJay can you look into it. For value formatting, we use Decimal Formatter with a pattern, and symbols are not added.

1. During Language change in the Application, the numbers should not change the Format. But it is changing for some Languages.

Solution: Add Symbols parameter using DecimalFormatSymbols. or add an extra parameter to add by the user.

2. In Some Devices, while using LargeValueFormatter to make it pretty in the code written by Roman Gromov the patter "###E00" is returning the end with e00 and Further String operations are not done as expected.

Solution : Replace regex can be changed to "[E|e][0-9][0-9]". If this is used then the Language Change Cannot be done as we get the regex in the other language formats.

you can custom like this

class ChartNumberFormat : ValueFormatter() {

    override fun getFormattedValue(
        value: Float
    ): String {
        // Menggunakan long untuk angka yang lebih besar dari int
        val trillion = 1000000000000L // Miliaran
        val billion = 1000000000L // Miliaran
        val million = 1000000L // Juta
        val thousand = 1000L // Ribu

        return if (value >= trillion) {
            String.format(Locale("in", "ID"), "%.2f T", value / trillion) // Format untuk trillion
        } else if (value >= billion) {
            String.format(Locale("in", "ID"), "%.1f B", value / billion) // Format untuk miliaran
        } else if (value >= million) {
            String.format(Locale("in", "ID"), "%.0f M", value / million) // Format untuk juta
        } else if (value >= thousand) {
            String.format(Locale("in", "ID"), "%.0f K", value / thousand) // Format untuk ribuan
        } else {
            value.toInt().toString() // Format untuk angka di bawah ribuan
        }
    }
}

and add ChartNumberFormat to valueFormatter

val leftAxis: YAxis = chart.axisLeft
leftAxis.textSize = 12f
leftAxis.valueFormatter = ChartNumberFormat()
leftAxis.axisMinimum = 0f // this replaces setStartAtZero(true)
leftAxis.textColor = getColor(requireActivity(), R.color.black_color)
leftAxis.granularity = 1.0f
leftAxis.isGranularityEnabled = true
