MtxVecTee.DrawIt Method

Overload List

#	Signature	Description
1	void DrawIt(TMtx a, String caption)	Shows form with chart and grid series showing matrix values.
2	void DrawIt(TVec x, TVec y, String caption, Boolean pixeldownsample)	Shows form with tChart and FastLine series showing Y=Y(X).
3	void DrawIt(TVec a, Int32 width, Int32 height)	Shows form with tChart and FastLine series showing vector values.
4	void DrawIt(TVec a, String caption, Boolean pixeldownsample)	Automatically creates modal form with tChart and appropriate series style and then uses method to draw values to created series.
5	void DrawIt(TVec[] a, String[] seriescaptions, String caption, Boolean pixeldownsample)	Shows form with chart and array of fastline series - one for each vector in A array of vectors.

Overload 1: void DrawIt(TMtx a, String caption)

Shows form with chart and grid series showing matrix values.

#	Name	Description
1	a	Source matrix.
2	caption	Form text.

Result: stored in self (calling object)

Examples

Matrix m1 = new Matrix(0,0,false);

m1.LoadFromFile("PCA_data.mtx");
MtxVecTee.DrawIt(m1,"Correlation matrix");

Overload 2: void DrawIt(TVec x, TVec y, String caption, Boolean pixeldownsample)

Shows form with tChart and FastLine series showing Y=Y(X).

#	Name	Description
1	x	Source x values vector.
2	y	Source y values vector.
3	caption	Form text.
4	pixeldownsample	If true, DrawIt will automatically use PixelDownSample method for series to reduce the number of points displayed (much faster display).

Result: stored in self (calling object)

Examples

using Dew.Math;
using Dew.Math.Tee;

Vector x = new Vector(0);
Vector y = new Vector(0);
x.LoadFromFile("xdata.vec");
y.LoadFromFile("xdata.vec");
MtxVecTee.DrawIt(x,y,"y=y(x)",false);

Overload 3: void DrawIt(TVec a, Int32 width, Int32 height)

Shows form with tChart and FastLine series showing vector values.

#	Name	Description
1	a	Source vector.
2	width	Form width.
3	height	Form height.

Result: stored in self (calling object)

Remarks:

The width and height parameters control form width and height respectively.

Examples

using Dew.Math;
using Dew.Math.Tee;

Vector v = new Vector(0);
v.LoadFromFile("c:\\data\\testvector.vec");
MtxVecTee.DrawIt(v,400,300);

Overload 4: void DrawIt(TVec a, String caption, Boolean pixeldownsample)

Automatically creates modal form with tChart and appropriate series style and then uses method to draw values to created series.

#	Name	Description
1	a	Source vector.
2	caption	Form text.
3	pixeldownsample	If true, then DrawIt will automatically use PixelDownSample method to reduce the number of points displayed for all series (much faster display)

Result: stored in self (calling object)

Examples

using Dew.Math;
using Dew.Math.Tee;

Vector v = new Vector(0);
v.LoadFromFile("c:\\data\\testvector.vec");
MtxVecTee.DrawIt(v,"Showing vector values",false);

Overload 5: void DrawIt(TVec[] a, String[] seriescaptions, String caption, Boolean pixeldownsample)

Shows form with chart and array of fastline series - one for each vector in A array of vectors.

#	Name	Description
1	a	An array of source vectors.
2	seriescaptions	An array describing each series(vector) title.
3	caption	Form text.
4	pixeldownsample	If true, DrawIt will automatically use PixelDownSample method for series to reduce the number of points displayed (much faster display).

Result: stored in self (calling object)

Examples

Vector x1 = new Vector(0);
Vector x2 = new Vector(0);
Vector x3 = new Vector(0);

x1.LoadFromFile("x1_data.vec");
x2.LoadFromFile("x2_data.vec");
x3.LoadFromFile("x3_data.vec");
MtxVecTee.DrawIt(new TVec[] {x1,x2,x3},new string[] {"1st","2nd","3rd"}, "Multiple values",false);
