ChartDataUpperLimits

ChartDataUpperLimits ( maxValue1 ;​ maxValue2 ;​ . . . ;​ maxValue10000 )

Examples

Description

Both functions, ChartDataUpperLimits() and ChartDataLowerLimits() , make it possible to define an upper and lower limit for each data series, i.e. all values which are less than minValue or greater than maxValue are not shown. The functions can be used to draw incomplete data series: missing data, such as missing readings, is substituted by "invalid" values, i.e. by values which are less than minValue or greater than maxValue. A different and easier method for passing incomplete series of values is to replace the missing values with NULL. Example:

	CHART_DATA_UPPER_LIMITS_01

1	OpenDrawing(250;​150)
2	/* 9999..."missing value" */
3	ChartData(1 2 3 4 5 6 7 8 9;​
4	7 16 11 9999 9999 6 4 9999 3)
5	ChartDataUpperLimits(1000)
6	ScatterChart2D()
7	/* Set up styles. */
8	SymbolStyle(1;​bullet;​5;​1;​#3879aa;​shaded)
9	/* Set up axes. */
10	AxisLine(all;​0)
11	AxisMajorTicks(all;​0)
12	/* Set up grid. */
13	MajorGridLineWidths(all;​all;​0.25)
14	CloseDrawing()

	CHART_DATA_UPPER_LIMITS_02

1	OpenDrawing(250;​150)
2	/* Replace missing values with "null". */
3	ChartData(1 2 3 4 5 6 7 8 9;​
4	7 16 11 null null 6 4 null 3)
5	ChartDataUpperLimits(1000)
6	ScatterChart2D()
7	/* Set up styles. */
8	SymbolStyle(1;​bullet;​5;​1;​#3879aa;​shaded)
9	/* Set up axes. */
10	AxisLine(all;​0)
11	AxisMajorTicks(all;​0)
12	/* Set up grid. */
13	MajorGridLineWidths(all;​all;​0.25)
14	CloseDrawing()
