How to draw an ellipsis as position reference in Google Scatter Chart? - charts

How can I draw shapes like the ellipsis showed in the following image in Google Charts?
The data that I have to plot is better represented by the Scatter Chart, but I don't see how I could draw the lines and ellipsis knowing their equation.

Do ILNumerics .NET Visualization Engine support the following features regarding 3D surface chart?

I would like to know whether the following features are supported in .NET Visualization Engine of ILNumerics
Draw a 3D Surface Plot
Layout a wireframe over the Surface Plot
Draw a scatter plot over the Surface Plot
Color the surface using custom values and show the color bar as a legend.
Custom meshgrid with support for floating point values.
Able to Zoom, Pan and Rotate the plot
Tooltip support together with the ability to select a point from the Surface plot (maybe using mouseclick/crosshair etc). I need a callback function from the point selected.
Modify axis properties such ticks, labels, titles etc.
Lighting and Shading options in the chart.
Please do reply
Yes, all is supported. Start with the visualization documentation: http://ilnumerics.net/Visualization-API.html
The examples section contains many runnable examples, including this one dealing with mouse picking on 3D surface plots.

How to bubble chart aligned bottom and stick to each other

I would like to ask if there is a way to achieve the layout and arrangement of the circles on the image.
I would like create a chart of series of circles that are link together and all aligned in the bottom.
The distance between two circles with radii r1 and r2 is:
You can use this to position your circles on the x-axis. For an example see: http://bl.ocks.org/7a9d6c4725367aaed5db .

Plot lines get under the X-axis in Core Plot

I've changed the look of my plots, and now the line of the plots accidentally goes under the X-axis. The problem looks like this (notice the black lines under the axis):
How can I get rid of it? I've change the plot line like this:
aaplPlot.interpolation = CPTScatterPlotInterpolationCurved;
Plots do not draw outside the plot area. You can control its size by setting padding on the plot area frame to push the edges of the plot area inwards. You will also need to adjust the plot ranges of the plot space to keep the same appearance.

Controlling the spacing between markers in a plot in a figure

How do I control the spaces between markers in a plot so that it although I am plotting say a 100,000 points but it shows markers at only sample points, and does not show markers when the plot drops between two points
A sample is shown in figure below:
The crudest way to do so is to plot each line twice: once without the markers, but with all the points. The second time you plot only a sample of the points with no line, but only with the markers.

Draw Matlab graphs with frame, ticks, on top of graph lines

Consider something like
figure
plot(sin(0:0.01:pi))
axis tight
set(gca,'box','on','ticklength',[0.02 0.05])
then export the graph to PDF or whatever. The lines of the graph are on top of the tick labels and the axes. (Furthermore, the lines of the axes don't meet correctly, but that's another story.)
Is there a way (that can be automated) to have the axes drawn on top?
Try:
set(gca, 'Layer','top')
according to the documentation page:
Layer
{bottom} | top
Draw axis lines below or above graphics objects. Determines whether
to draw axis lines and tick marks on
top or below axes children objects for
any 2-D view (for example, when you
are looking along the x-, y-, or
z-axis). Use this property to place
grid lines and tick marks on top of
images.
and to visually see the effect (zoomed in 1200%), I save the figure as a PDF file:
Default (Layer=bottom):
with Layer=top:
