CT Chart arrays


CT Chart arrays ( area ; type ; size ; categoryArray ; seriesArray ; valuesArray ) -> Function result

Parameter	Type	Description
area	Longint	4D Chart area
type	Integer	Type of graph (see codes below)
size	Integer	Option for initial size of graph 1 = Variable 2 = Relative to window (Auto-Variable) 3 = Relative to graph (Auto-Document)
categoryArray	Array	Array of categories
seriesArray	Array	Array of series
valuesArray	Array	Array of values
Function result	Longint	Object ID number

Description

CT Chart arrays creates a graph based on the specified arrays and returns the graph’s Object ID. This command can be used to create either a two-dimensional or three-dimensional graph.

The following table lists the codes for the type parameter.

Code	Chart Type
1	Area
2	Column
3	Picture
4	Line
5	Scatter
6	Pie
7	Polar
8	2D XY
100	3D Column
101	3D Line
102	3D Area
103	3D Surface
104	3D Triangle
105	3D Spike

The size parameter determines how much space the graph fills when it is generated and how the graph size changes when you resize the window:

If you pass 1 (size Variable), the graph will fill the 4D chart area or the window. It will keep this size until you modify it using the handles.
If you pass 2 (size Relative to the window), the graph will fill the 4D chart area or the external window. If you later change the size of the window, the graph will adapt automatically. However, once you modify the size of the graph using the handles, this change will not take place anymore.
If you pass 3 (size Relative to the document), the graph will adapt to the dimensions of the page that you selected in the Page Setup dialog. It will keep this size until you modify the graph size using the handles.

The categoryArray parameter contains the X-axis categories.

seriesArray contains the series. In a two-dimensional graph, the series is displayed on the Category axis. In a three-dimensional graph, the series is displayed on the Series axis.

valuesArray is a one-dimensional array that contains all the values to be graphed on the Values axis. valuesArray must be filled in so that there is a value for each element of the categoryArray and seriesArray. That is, if there are n categories and m series, there will be n*m elements in valuesArray.

The following illustration shows the order in which valuesArray should be filled. n represents the total number of categories. m represents the total number of series.

For example, consider the following data and resulting Values array:

School (Categories)	Year (Series)	Students(Values)	aValues
Sunnyoaks	1990	1000	aValues{1}:=1000
Sunnyoaks	1992	1250	aValues{2}:=600
Sunnyoaks	1994	800	aValues{3}:=1250
Valley	1990	600	aValues{4}:=975
Valley	1992	975	aValues{5}:=800
Valley	1994	1100	aValues{6}:=1100
