You can learn by reading a few books on C#.
There will be a number of samples that you could try from these books.

Searching on the internet should give you enough reading information to learn both basic and advanced OOPS.

You could, of course, begin with wiki -http://en.wikipedia.org/wiki/Encapsulation_%28object-oriented_programming%29[^].

Why is my windows chart so small, I cant change the size

Re: Why is my windows chart so small, I cant change the size

I have created a windows form chart and it is very small the only way I can change its size is by stretching the chart but it is only a percentage of the charts container size, I have spent forever going through the properties and I cannot see what is affecting it, here is an image of it:

You can see the white are is the size of the chart but it is nowhere near the same size, can anyone tell me why?

Thank you!!

Without knowing what you're using for a chart control or if you made your own, it's pretty much impossible to help you.

I apologise for the lack of information in my question!

I am using this:

using System.Windows.Forms.DataVisualization.Charting;

The code for my chart properties in the designer file is as follows:

//
           // chart1
           //
           chartArea1.Name = "ChartArea1";
           this.chart1.ChartAreas.Add(chartArea1);
           legend1.Name = "Legend1";
           this.chart1.Legends.Add(legend1);
           this.chart1.Location = new System.Drawing.Point(0, 0);
           this.chart1.Name = "chart1";
           series1.ChartArea = "ChartArea1";
           series1.Legend = "Legend1";
           series1.Name = "Plots";
           series2.ChartArea = "ChartArea1";
           series2.Legend = "Legend1";
           series2.Name = "Regression Line";
           this.chart1.Series.Add(series1);
           this.chart1.Series.Add(series2);
           this.chart1.Size = new System.Drawing.Size(1212, 771);
           this.chart1.TabIndex = 13;
           this.chart1.Text = "chart1";
           this.chart1.Click += new System.EventHandler(this.chart1_Click);

I am new to this kind of project So forgive me if there is still something missing.

Thank you!

The code isn't here, but you may have set the size of the ChartArea1 in the designer to be a fixed size instead of Auto.

I preffer to remove all of the default collection items that dropping the chart object on the form adds, including all Legends, ChartAreas, Series, Annotations, ... and just create everything in code and add them to the appropriate collectiosn manually instead of modifying what's there. I did this without any problems:

Dim chartArea As New ChartArea("TestChartArea1")
chartArea.AlignmentOrientation = AreaAlignmentOrientations.All
chartArea.AlignmentStyle = AreaAlignmentStyles.All
Chart1.ChartAreas.Add(chartArea)

Dim legendArea As New Legend("TestLegend1")
Chart1.Legends.Add(legendArea)

Dim series As New Series("Series1")
series.ChartArea = "TestChartArea1"
series.ChartType = DataVisualization.Charting.SeriesChartType.Line
series.XValueType = DataVisualization.Charting.ChartValueType.Int32
series.YValueType = DataVisualization.Charting.ChartValueType.Int32

For Each p In New Integer() {1, 2, 3, 4}
    series.Points.AddXY(p, p)
Next

Chart1.Series.Add(series)

Create a list containing the names and save it in your database. Load the list as required.

But actually , i am looking for a solution like with out storing that list in my db.

AFAIK, there's no public list available; you'd have to make (and maintain!) your own.

Should also note that the solution will likely vary by country.

I suspect also that the usable definition of "bank" might vary as well.

Ho to draw a regression line in windows forms charts?

Storing the data should not be too difficult.
Have two tables, one with the bank name joined to another that is contains country data.

The likely problem here is collating this data from a reliable source.

Re: Ho to draw a regression line in windows forms charts?

2-Feb-13 9:00

Hey guys, I have pretty much figured out my regression line doing some calculations, but drawing it is where I am stuck. The line comes from the y axis and goes through the middle of the chart roughly, once I get these two points I draw the line, but I do not know how to draw a line THROUGH the middle point to the end of the chart, can anyone please help me out?

Here is my chart code:

chart1.Series["Regression Line"].Points.AddXY(0, b0);
           chart1.Series["Regression Line"].Points.AddXY(xAverage, yAverage);
           chart1.Series["Regression Line"].ChartType = SeriesChartType.Line;
           chart1.Series["Regression Line"].Color = Color.Red;

You can see the line goes from one point to another, but its only half the line, any assistance would be greatly appreciated I am completely stumped!

Many thanks!!!

The maths is pretty simple. If you have a line from (x0, y0) to (x1, y1) and want to extend it as far again to (x2, y2), then (x1, y1) is the midpoint of the line. x1 = (x0 + x2) / 2, etc.

Massage it a bit and you get
x2 = 2 * x1 - x0, y2 = 2 * y1 - y0.
Refactor to your variable names and that's it

Cheers,
Peter
