MtxVecTee.DrawValues Function

Draws vector or matrix values by using any valid already created chart series.

Pascal

procedure DrawValues(Y: TVec; Series: TChartSeries; XOffset: double = 0; XStep: double = 1.0; PixelDownSample: boolean = false); overload;

MtxVecTee

Description

Plots a Y=Y(X) using Series. X values are calculated using the following formula

X[i] = XOffSet + XStep*i

If parameter PixelDownSample is True, then DrawValues will automatically use PixelDownSample method to reduce the number of points displayed (much faster display).

Example

Plot Y=Y(X) with starting point for x values equal to 10.5 and x step equal to 0.05.

You have to put a chart on the form and add it one series which should be named "Series1".

uses MtxExpr, Math387, MtxVec, MtxVecEdit; procedure TForm1.FormCreate(Sender: TObject); var Y: Vector; // Series1: TMtxFastLineSeries; begin Y := Sin(Ramp(100,0,2*PI*5/100)); DrawValues(Y, Series1, 10.5, 0.05); end;

#include "MtxExpr.hpp" #include "MtxVecTee.hpp" __fastcall TForm1::TForm1(TComponent* Owner): TForm(Owner) { sVector Y; // TMtxFastLineSeries Series1; Y = Sin(Ramp(100,0,2*PI*5/100)); DrawValues(Y, Series1, 10.5, 0.05); }
