Introduction

For one of my previous projects, I needed to display a continuous flow of data on a charting control. I decided to

develop my own control because I couldn't find any free control that could provide the required flexibility. One of

the main restrictions was that the control had to plot a lot of data and be able to display it quickly (on a Pocket

PC). The control should be able to do that by plotting only the new points of data, not the complete series. The

chart should also, of course, be able to display static data.

This article contains two main parts: a section that describes how to use the control, and a section that lists all the

classes and their functionalities. With the first part, you will be able to quickly integrate the control inside your

application. If more advanced control is required, the second part will be useful because it lists the properties of all

the objects of the chart.

Disclaimer

This control is the result of a lot of hours of development, thus I'm placing some minor conditions on the use of the

code:

This code may be used for any non-commercial

and commercial purposes in a compiled form.

The code may be redistributed as long as it remains

unmodified and providing that the author name

and the disclaimer remain intact. The sources

can be modified with the author consent only.

This code is provided without any guarantees.

I cannot be held responsible for the damage or

the loss of time it causes. Use it at your own risks.

This is not too much to ask considering the effort spent on the development of this control. If this code is used in a

commercial application, then please send me a mail letting me know.

The main features of the control are:

High-speed drawing (when axis is fixed) which allows fast plotting of data.

Unlimited number of series (memory is the limitation).

Unlimited amount of data per series.

Line and point series available.

Up to four axes (left, bottom, right, and top axes).

Logarithmic, automatic, and/or inverted axes (independent from each other).

Axis labels.

Grid.

Legend and titles.

Support for manual zoom and mouse panning.

Highly customizable (colors, titles, labels, edge, fonts, etc.).

How to use the control

In order to be able to use the chart control in your application, you first need to add the files contained in the

sources Zip in your project. There are two ways of using the chart control within your application: inserting it

manually, or through the resource editor.

Manual insertion

#include "ChartCtrl" at the top of your dialog header file.1.

Add a variable of type CChartCtrl in your dialog class:

//{{AFX_DATA(CChartDemoDlg)

//}}AFX_DATA

CChartCtrl m_ChartCtrl;

In the OnInitDialog of your dialog class, call the Create method of the control.3.

Using the resource editor

Add a custom control to your dialog resource, open the Properties tab, and insert "ChartCtrl" (without

quotes) for the "Class" attribute.

#include "ChartCtrl.h" at the beginning of your dialog header file.2.

Add a variable of type CChartCtrl in your dialog class:

//{{AFX_DATA(CChartDemoDlg)

//}}AFX_DATA

CChartCtrl m_ChartCtrl;

Add a DDX_Control line in the DoDataExchange function in the CPP file of your dialog class (don't forget to

change the ID and the name to the appropriate values):

void CChartDemoDlg::DoDataExchange(CDataExchange* pDX)

{

CDialog::DoDataExchange(pDX);

//{{AFX_DATA_MAP(CChartDemoDlg)

// Add this line with the appropriate ID and variable name

DDX_Control(pDX, IDC_CHARTCTRL, m_ChartCtrl);

//}}AFX_DATA_MAP

}

Adding data to the chart

Once the chart is ready to be used, you can add data to it. As the chart can have multiple series, you first need to

add at least one series (there is no maximum limit for the series number). A series can be of different types; for

now, only line and point series are supported.

CChartLineSerie* pLineSerie =

static_cast<CChartLineSerie*>

(m_ChartCtrl.AddSerie(CChartSerie::stLineSerie));

CChartPointsSeries* pPointSerie = static_cast<CChartPointsSerie*>

(m_ChartCtrl.AddSerie(CChartSerie::stPointsSerie));
