Bug fix & memory improvements

deleted by marcellopoletti

Attached an example of my ideas.
Is a "blind chart" that not draw series but zomm/pan, track points, rotation, axis inversion, track labels are enabled.

Test chart works with 20 series with 100.000 points each with great performances (see http://feedback.telerik.com/Project/143/Feedback/Details/198264-ordered-dataset-for-ultraefficient-trackbals-engine-and-pan-zom-behavior). Look that it can work also with 50 milions of points [consuming a lot of memory] with same performances!

Look architectural differences with current telerik chart component:

- You can assign/change/move X/YAxes to a series without problems
- You can rotate chart without problems
- DataSource can be extremely efficient.
- You can define/change zomm/pan [For axis, not for chart!] without problems.

A little fragment of pseudocode that shows what will be wonderfull!

Suppose that we want to create a scatter chart with three series and two Y axes, left and right.

- let S1 a data series with 10 values, on left axis
- let S2 a trend linear series, based on S1 values, on left axis
- let S3 a annotation series that simply show cos(x) foreach zoom pan, on right axis

First, we define chart and axis

var c=new Chart();
c.XAxes.Add(new DoubleAxis());
c.YAxes.Add(new DoubleAxis());
c.YAxes.Add(new DoubleAxis(){Position:Right});

Now, we define the Datasources:

//the RandomDoubleDataSources generate N points starting from start value. X values step is step value.
var d1 = new RandomDoubleDataSources(points:10, start:0, step:1)
//the TrendDataSource generate trend line points using a source datasource
var d2 = new TrendDataSource(d1){Algorithm = Linear}
//The function series can generate N values for each zoom/pan range based on a function
var d3 = new FunctionDataSource((v)=>{return Math.Cos(v)})

//So, the series
var s1 = new Series(){Description=“S1”, Datasource=d1, XAxis=0, YAxis=0}
var s2 = new Series(){Description=“S2”, Datasource=d2, XAxis=0, YAxis=0}
var s3 = new Series(){Description=“S3”, Datasource=d3, XAxis=0, YAxis=1}
c.Series.Add(s1,s2,s3);

Thats all, component can draw chart.
By default chart draw lines but we can add/change new renderers.

//Now we want to show s3 as columns:
s2.Renderers.Set(new ColumnsRenderer());

//Now we want to show markers in s1 (over the line, not instead of!)
s1.Renderers.Add(new MarkerRenderer());

//main properties and sub properties.
//now we want to set “main color” of line and marker of s1 as red:
a1.MainStroke = Brushes.Red; //!!!!

//now we want to set marker color of s1 as blue:
((MarkerRenderer )a1.Markers[1]).Stroke = Brushes.Blue; //!!!!

//now we want reduce opacity for every renderer in s1
s1.Opacity = 0.5;

//chart manipulation
//Now we want invert series y axes:
s1.YAxes=1;
s2.YAxes=1;
s3.YAxes=0;

//Now we want to rotate chart (X-Axis in left position)
c.Rotation = ChartRotation.RotateRight;

//now we want to add new x axes as ContinousDatetimeAxis and a new series:

c.XAxes.Add(new DoubleAxis(){Position:Top}); //Look that is not important that chart is now rotated!!! 
var d4 = new RandomDateTimeDataSources(points:10, start:System.Datetime.Today, step:new System.TimeSpan(day:1));
var s4 = new Series(){Description=“S4”, Datasource=d4, XAxis=1, YAxis=1}
c.Series.Add(s4):
