This is an example of an animated graph. I want to replicate this

I'm using leafletjs with a custom large image where I am serving the tiles from my local server.
I need to display a minimap that shows what is currently visible on screen, what would be best to use in these circumstances?
Is there something already available in leafletjs or do I need to use a plugin or build a custom one?
I saw this one but it seems kind of specific to using a map: https://github.com/Norkart/Leaflet-MiniMap
Dynamic Data Display is a fantastic library that so far has been very useful for me. Thanks go to Mikhail Brinchuk for developing the library.
This posting gives a great tip for adding controls to DynamicDataDisplay charts using xaml that pan and zoom with the chart content: https://dynamicdatadisplay.codeplex.com/discussions/74886
This allows the placement of an image, text, or whatever, on the chart that moves with the chart axes. This is all done in xaml.
How do I add these in the cs code such that I can add controls to the chart (markers, images and such) at run-time? I'm trying to plot some GPS data in one chart using Google maps as the source images. In another chart I'd like to add controls that pan with the data. The above link does this, but I am not able to add it at run-time, nor specify the position in my chart data.
As a console app, I'm creating maps with Bing Maps, with lat/lon and pushpins. Saving as a jpg. Everything is working great. NOW, however, I'd like to draw a polygon layered on said map[s]. It seems this might not be possible; I cannot find the answer. Dynamic via web page it seems is the only way; I need it to happen with a console app.
The custom polygon as well as custom polyline are not supported features on the REST service.
Since you're in a console application and as you're saving the image as JPG file, you can draw your own content onto the image using GDI or other technology to manipulate the image directly. Currently, there is no other way.
I would like to use the Core Plot framework to produce a graph that looks like the following:
Additionally, I would like to provide charts within a table view like the following:
How would I set up charts like these using Core Plot?
The first one is easy--it's just a scatter plot with a gradient fill. The examples included with the framework show how to do this.
See this thread on the Core Plot discussion board for ideas on how to approach the second problem: http://groups.google.com/group/coreplot-discuss/browse_thread/thread/00344ef4e0234a51

You can refer this link for installing core-plot.

I'm writing a stock charting application on iPhone using core-plot. What kind of chart should I use to plot the volume chart? Since I will also need to overlay the price charts onto the volume chart, how should I go about doing this?
Here's an image for reference (By no means am I trying to reimplement stockcharts functionality, just wanted to create a simple charts with volume information overlaid on the price charts):

Thanks!
What about using a Javascript charting library inside a WebView for your charts? You could then use something like Emprise: http://www.ejschart.com/
If you look at the latest builds of the framework, Drew just added an open-high-low-close plot type, which is a CPTradingRangePlot with a CPTradingRangePlotStyleOHLC plot style. For an example of this in action, along with a bar chart tracking trading volume, see the latest version of the AAPLot example application that ships with the framework:

Well i don't think its possible using current build of core-plot. But you can write a implementation of your own OR in best case extend core-plot to do that & submit a patch so other can benefit from your work.
Read Quartz 2D Drawing API & you will easily be able to create a complicated graph like above.
