Types
ChartDataValue = object case kind*: ChartDataValueType of INTEGER_VALUE: ival*: int of FLOAT_VALUE: fval*: float of STRING_VALUE: sval*: string of CHAR_VALUE: cval*: char
ChartData = ref object chart_type*: ChartType data_color*: ColorRef data_name*: string x_axis*: seq[ChartDataValue] y_axis*: seq[ChartDataValue]
Procs
proc newChartData(data_name: string = "data"; data_color: ColorRef = Color(); chart_type: ChartType = LINE_CHART): ChartData {...}{.raises: [], tags: [].}
-
Creates a new empty ChartData.
Example:
var my_chart_data = newChartData()
proc newChartData(x_length, y_length: int; data_name: string = "data"; data_color: ColorRef = Color(); chart_type: ChartType = LINE_CHART): ChartData {...}{.raises: [], tags: [].}
-
Creates a new ChartData with specified length.
Arguments:
- x_length -- length of x_axis;
- y_length -- length of y_axis.
Example:
var my_chart_data1 = newChartData(5, 5)
proc newChartData(x_data, y_data: seq[ChartDataValue]; data_name: string = "data"; data_color: ColorRef = Color(); chart_type: ChartType = LINE_CHART): ChartData {...}{.raises: [], tags: [].}
-
Creates a new ChartData from specified data.
Arguments:
- x_data -- specified data for x_axis;
- y_data -- specified data for y_axis.
Example:
var my_chart_data2 = newChartData(@[1, 5, 2], @["10.10.2021", "10.11.2021", "10.01.2021"])
proc findMax(data: seq[ChartDataValue]): ChartDataValue {...}{.raises: [], tags: [].}
- Returns max value from sequence.
proc findMax(chart_data: ChartData): tuple[x, y: ChartDataValue] {...}{.raises: [], tags: [].}
- Returns max values from ChartData.
proc len(data: ChartData): int {...}{.raises: [], tags: [].}
- Returns length of the data.
proc getNum(val: ChartDataValue): float {...}{.raises: [], tags: [].}
- Returns numeric value of the chart data value.
proc `$`(val: ChartDataValue): string {...}{.raises: [], tags: [].}
proc getSorted(data: ChartData): seq[tuple[x, y: ChartDataValue]] {...}{.raises: [], tags: [].}
proc getSum(data: ChartData): float {...}{.raises: [], tags: [].}
