we are developing an windows 8 store apps and telerik charts to display charts. In one of the charts we need to show the chart having 2 y-axis and bar series need to bind to left side of the y-axis and line series need to bind data to right side of the y-axis(secondary y-axis). So i posted in one of the forum and got reply form them and i like to share the answer.
Here is the solution I suggest. You have to create a class that inherits the Collection class in your project.
public class CustomAxes : Collection<Axis> { }
This will make it possible to define custom collection of axes that will be used by the corresponding series. Next you have to create CustomAxes object in the resources of your application and fill it with the axes you want to have in your chart:
<local:CustomAxes x:Key="customAxes">
<telerik:LinearAxis HorizontalLocation="Left"/>
<telerik:LinearAxis HorizontalLocation="Right"/>
</local:CustomAxes>
Now you have to bind the vertical axes of your series to the custom axes:
<telerik:BarSeries VerticalAxis="{Binding Source={StaticResource customAxes}, Path=[0]}">
Here is the sample code attached in this forum.

I am trying to write a pine script with two indicators one overlaid on the chart (EMA) and another on its own?(Stoch) I cannot seem to find any info on how to separate these (Visually) but keep them within 1 pine script, ie to be able to take trading decisions based on these.
The earlier answer from Luc is right, unfortunately. Each script can either create plots that are overlaid on the default price chart, or shown in a different pane, but not both. But there is a workaround.
Suppose you've made some non-trivial calculation in your script and you'd like to put it in different pane. E.g. the next code:
//#version=4
study(title="Stochastic", shorttitle="Stoch", format=format.price, precision=2)
periodK = input(14, title="K", minval=1)
periodD = input(3, title="D", minval=1)
smoothK = input(3, title="Smooth", minval=1)
k = sma(stoch(close, high, low, periodK), smoothK)
d = sma(k, periodD)
plot(k, title="%K", color=color.blue)
plot(d, title="%D", color=color.orange)
h0 = hline(80)
h1 = hline(20)
fill(h0, h1, color=color.purple, transp=75)
// This next plot would work best in a separate pane
someNonTrivialCalculatedSeries = close
plot(ema(someNonTrivialCalculatedSeries, 25), title="Exporting Plot")
Because they have different scale, one of them most likely will break another indicator's scale.
So you'd like show Stoch in different pine, whereas ema() should be overlayed with the main chart. For that you should make the next steps:
Turn off in the study's the extra plot to return scale to normal:
Apply to the chart the next script:
//#version=4
study("NonOverlayIndicator", overlay=true)
src = input(defval=close, type=input.source)
plot(src)
Choose in the second's script inputs source required plot from the first script:
And voilà - you got the plots in different pines:
But if you want split the plots because you have retrictions on amount of studies you allowed to apply (e.g. 3 for free-account) - that won't help you.
It cannot be done. A script runs either in overlay=true mode on the chart, in which case it cannot direct plots elsewhere, or in a separate pane when overlay=false (the default).
When the script is running in a pane, it can change the color of the chart bars using barcolor(), but that's the only way it can modify the chart.
It is possible to rescale signals so that multiple bounded (e.g., 0-100, -1 to +1) signals generated by one script appear one on top of the other, but this is typically impossible in overlay mode, as the vertical scale varies with the bars on the chart. The only way for an overlay script to work with its own scale is when it uses No scale, but this prevents the indicator's plots to plot relative to price, and so the chart's bars.
Nice workaround from Michael.
Unfortunately, this only seems to work to pass data for one plot.
I would like to pass data for 3 different plots to the stock price graph.
If I try this, for 'input.source' I can only select the standard sources: "open, high, low, close ...". I can not select the data from other indicators.
If I remove plots 2 and 3, it works as Michael described.
Anybody has a workaround for the workaround..? ;-)
I am now using the MPAndroidChart to draw line chartmy chart
As you can see from the above screenshot, the color specified by me(showed in legend) is not the same as the finally filled in below the chart, is there any way to make sure that the different color will not mixed together?
Below is the code I used to draw two of the lines
LineDataSet vlfDs = new LineDataSet(vlfValues, "VLF");
vlfDs.setMode(LineDataSet.Mode.CUBIC_BEZIER);
vlfDs.setCubicIntensity(0.2f);
vlfDs.setDrawFilled(true);
vlfDs.setDrawCircles(false);
vlfDs.setLineWidth(0);
vlfDs.setCircleRadius(4f);
vlfDs.setColor(Color.YELLOW);
vlfDs.setFillColor(Color.YELLOW);
vlfDs.setFillAlpha(100);
LineDataSet lfDs = new LineDataSet(lfValues, "LF");
lfDs.setCubicIntensity(0.2f);
lfDs.setDrawFilled(true);
lfDs.setDrawCircles(false);
lfDs.setLineWidth(0);
lfDs.setCircleRadius(4f);
lfDs.setCircleColor(Color.WHITE);
lfDs.setColor(Color.GREEN);
lfDs.setFillColor(Color.GREEN);
lfDs.setFillAlpha(100);
hrvLineData = new LineData(hfDs,lfDs,vlfDs, hrDs);
hrvLineData.setValueTextSize(0);
hrvLineData.setDrawValues(false);
hrvChartView.setData(hrvLineData);
hrvChartView.invalidate();
It's turned out that I need to use setFillAlpha(255) instead of setFillAlpha(100)
You can also use something similar to the following solution which overrides the default LineChartRenderer and a uses a custom implementation of IFillFormatter to fill only the areas between the datasets.

I am using wso2cep dashboard for displaying network traffic related information by exploiting various graphs. I was wondering if there is any way I can customize legend for each type of graph or set it globally as its create confusion for the viewer, elaborated in screen shot.
In piechart others = blue
In dest port vs src ip other = orange
One thing more
Scatter plot is shifted to left side of the window cutting ips on the y-axis and there is a space left on right side which can be used.
How can I drag the chart towards right side?
And also scatter chart is not rendering multiple y-axis values against single x-axis value. Here is the screen shot for that and values against it is plotted.

This is happening because generated gadgets are deciding the the color scale and domain dynamically based on the data that has been passed to chart.
If you want to explicitly specify the color domain and color scale you can configure those in generated gadgets by modifying the VizGrammar (which is the chart library used) configuration of the charts.
This can be done by changing chart api js file, there will be a config creation like this [1] and there add colorDomain for you predefined options like below. Then the domain will be defined statically without dynamically changing the order and the colors has to be constant
conf.colorDomain = ["MySQL","SMB","OTHER"]
Even you can define your own colors to

In Sencha's API for border layout it says:
There is no BorderLayout.Region class in ExtJS 4.0+
What I found on various blogs, for accessing the center panel was this:
var viewPort = Ext.ComponentQuery.query('viewport')[0];
var centerR = viewPort.layout.centerRegion;
Again to the docs, I see that centerRegion is a private function (why?), and I don't care to rely on those, for future proofing. Also, there is no westRegion, northRegion, etc...
How does one get to these items?
I could of course get the items inside the regions: The various panels, and such, but I want complete control of the viewport that holds my border layout.
This is what I'm doing now:
var viewPort = Ext.ComponentQuery.query('viewport')[0];
var view = Ext.widget('my-new-tab-panel');
viewPort.layout.centerRegion.removeAll();
viewPort.layout.centerRegion.add(view);
Is there a better way?
Usually, I setup an id for each container I have to work with. So, my center region will have an id and I'll get it with Ext.getCmp() function.
Otherwise, to access to the viewport items you can do as follows:
var viewPort = Ext.ComponentQuery.query('viewport')[0];
var view = Ext.widget('my-new-tab-panel');
viewPort.items.items[0].removeAll();
viewPort.items.items[0].add(view);
If you've defined center region as the first item of viewport, then the above code it's ok but if you've defined it as the third or the fourth, then you have to change the index according to the position of your region (viewPort.items[3] or viewPort.items[4], etc).
Another way is to use query selector:
var cr = viewPort.down('panel[region=center]');
cr.removeAll();
cr.add(view);
However, following this way, you have to query on a precisely xtype (as panel in this case).
Anyway, I think the best way is to use an id for each region.
Can anyone help me? it seems no way to do this in blend 4
With Blend 4 open, go to Data tab.. hit the second icon from right("Create sample data").. select "Create sample data from class.." and select your class. This will generate sample data source. You can bind your controls to this data source to see the controls filled with sample in Blend designer. HTH.
The method I'm using now - although really less than perfect - is by creating a dummy class which contains a list of items of the original class. I.e.:
class We_Want_Items_Of {}
class Dummy_Class { List<We_Want_Items_Of> Test {get;set;}}
Then you can create a sample datum for the Dummy_Class, which will contain a list of We_Want_Items_Of's. You can then use that list as a data source for, for instance, a ListBox.
