Introduction

I worked on a project in which I needed a graph control. Later on, I was also required to use a chart control. So I thought, hey, let's just combine them both into one nice and simple control.

Using the code

This control is very simple to use. First, we must create the control and initialize it.

//Creating the control
private ChartControl.ChartControlForm chartControlForm1;
chartControlForm1 = new ChartControl.ChartControlForm();
//Initializing the Control
chartControlForm1.InitChart();

Now we can start adding values.

//Adding Values to the control
float ValueAdd;
ValueAdd = 5.3;
chartControlForm1.AddValue(ValueAdd);

As we add the values, the control automatically redraws itself, so there is no need to call any function.

The variable in charge of the Graph/Chart mode is OpenType. Please note that its default value is ChartControlOpenType.Bar.

Change to Graph mode:

chartControlForm1.OpenType = ChartControl.ChartControlOpenType.Graph;

Change to Chart mode:

chartControlForm1.OpenType = ChartControl.ChartControlOpenType.Bar;

Additional Features

Loading from an array/list can easily be done by using the overloaded function LoadFromValues (may receive a float Array or an ArrayList).
