Nevron Chart X Axis

I have some charts and want if user zoom into a chart, other charts show the same range on X-axis and left lines of charts fit in a common vertical line(as shown in the picture)
how to that in Nevron charts?
The following code shows how to synchronize the ranges of the x axes as well as how to align the charts left panels:
Synchronize the axis range:
// make axes master slave
chart1.Axis(StandardAxis.PrimaryX).Slaves.Add(chart2.Axis(StandardAxis.PrimaryX));
chart2.Axis(StandardAxis.PrimaryX).Slaves.Add(chart1.Axis(StandardAxis.PrimaryX));
Align the charts:
// align the charts
NSideGuideline guideline = new NSideGuideline(PanelSide.Left);
guideline.Targets.Add(chart1);
guideline.Targets.Add(chart2);
nChartControl1.Document.RootPanel.Guidelines.Add(guideline);

Dynamic Points with shading

I am programming in C# on VB2010 and I am wanting to shade under the line that is made on my chart. I have a chart with 7 separate values on the X-axis and adjust them with a trackbar for the height on the Y-axis. First I would like to know how to have my line (I'm currently using the Spline type Series chart) display shading under where the line is to the bottom of my chart; and to also have my chart display the new value on the chart immediately after moving the trackbar so that I don't have to click on the chart to update the display.

how to plot multiple y-axis in chart control

I am creating a web application using c#. I have four values(or series) volt,current,wh and temperature which I will have to plot in a chart control against time which(time) will be shown in x-axis. All things done correctly. But the range of the values are different like one is in range of more than 1000,another lies between 0 to 10,another shows negetive value,etc. I want to create different y-axis for each series.I had created two y-axis which is a property of series(YAxisType),primary and secondary. Is it possible to create multiple y-axis?I had searched in google but didn't get any proper answer. Please help me.
You can only use 2 y-axis(primary and secondary)
But you can create a few chart areas within one chart control
Or you can add a button that will hide one chart control and show another(with others 2 axis)

Line not visible in zedgraph - How to create overlapping filled line graphs using zedgraph such that all the curves and their fills are visible?

I am creating a line graph using zedgraph which contains multiple lines and all of them are filled with labels displaying the data points. There are times when one of the lines is not visible at all but only the data point labels for that line are visible. I think this happens when the data is such that one line completely envelopes the other in terms of area covered and the order of rendering for the lines is such that the inner line is rendered before the container line. This I think is making the inner line invisible except for its data point.
So my question is:
How using zedgraph can I ensure that all portions of the filled curves along with their lines are rendered properly irrespective of their filled overlapping areas being subsets of each other and the order in which the curves are rendered?
How using zedgrapgh can I force the overlapping portions of the curves to display a fill color that is a resultant of the individual fill colors for the curves like in the chart image I found on google charts demo page below?
SOLVED!! - The only thing to do was add the alpha channel transparency to my line curve fills and everything else gets sorted automatically. Hope this helps someone.

Stairstepping piecharts with asp:chart control

I was perusing the asp.net chart control's sample website, and came across something in the pie chart gallery. There was 3 pie charts, "stair stepped" on top of each other. I starting using this control for a financial services application, and would like to replicate this effect. It looks like this:
3d Stair stepped Pie Chart http://www.freeimagehosting.net/uploads/87a5caabca.png
I'd post some code on what I've accomplished so far, but I have no idea where to start with this. I'm guessing maybe I'd have to create the 3 charts, and offset their axes, am I off base here? Any help would be appreciated.
You need to create 3 seperate series and assign them to seperate chart areas.
The chart areas need to stepped down the page using position.x and position.y
Other tricks include disabling the legend for the second and subsequent series.
To get the transparency affect you need to work at a data point level in the series. Note the Ownership data point is not transparent but the renting and leasing data points are.
