Can one provide me a example for the Custom Legend Tool. I Want to Show Data in a tabular Format at the bottom of the chart. Can't use Data Table since it display the Value which are used for the drawing the chart. I want to provide some product related Data in tabular format.
This tool isn't still fully usable in TeeChart ActiveX as you can read here.
Feel free to add your mail to the CC list to be automatically notified when an update arrives.
In the meanwhile, the only solution I can think on would be using custom drawing techniques: manually drawing your texts and shapes at OnAfterDraw event.

I'm looking for a way to indicate key dates on a highchart with a label eg Public Holiday. I can't find a way to add labeled guidelines or add an opened callout to a point? Help appreciated.
In Highstock you have series type called flags which is a opened callout (similar to Dygraphs annotation). This is probably the closest fit to the indicators you referred. See this JSFiddle example of how it looks. Note how this example uses the Highstock source file, but builds a Highcharts chart. See this documentation for official information.
In Highcharts you can highlight points, labels and value in a wide variety of ways. First of you can add data labels to your points, which renders text next to it. Secondly you can use plot lines to highlight certain values along an axis. See this JSFiddle example of how both of these options can be used.
Of course there are lots of ways to improve and build upon this out of the box functionality, but that is up to your specific demands and desires.
For a rails web application I need a timeline with on the top (stacked) bar charts and on the bottom single events that should be recognizably different using e.g. forms (squares, rhombus, circles) and colors.
It's also important that I get some kind of picture back in order to reuse it to build a pdf.
At the moment I do the bar chart part with google charts, but I can't find a way to do the events. Those could also be on a separate chart that I then align in html or the pdf.
have you ever try the highcharts.
Here is an example of time series with events made with amCharts: http://www.amcharts.com/stock-chart/stock-events/
You can have any number of graphs stacked on each other, if this is what you want to do.

I have a TPieSeries which looks like this image when populated with data. Not very bright... Can I instruct the pie series to show the top N most significant records, and summarize the rest in another slice named "Others"? So far, the only thing I've come up with has been to set chart paging and order my data so that the top N records are shown on the first page. I'm using TeeChart Standard v2011.03.32815 VCL.
Yes, you can do it using the OtherSlice property as shown in Yeray's example here.
I have a project that needs to produce reports in Delphi XE2 that have 4 elements per page. For instance, one page (11 x 8.5) landscape needs four quadrants
Rich text bulleted items in quadrant one
Bar chart in quadrant two and quadrant three
Pie chart in the final quadrant
Today, these reports are produced with a combination of Excel and Powerpoint which is very time consuming and I'd like to automate the process with a Delphi App.
I've had experience with Report Builder and Rave Reports, but I never ran into a situation where I needed to divide the page up into four areas. It was always the traditional single graph per page design.
Use Fastreport, it has Rich text and Chart objects and can make the layout that you want.
Just put one Rich text object and 3 chart objects on the page and fill them in the code.
You can use fastReport with subReports. Also you can activate the pages columns=2 and I think its possible to do it.
In FastReport you have all you say you need:
Pie Chart
Bar Codes
Ritch ext
And Group & master Detail Lists
One solution is to create you report and export it in pdf or jpeg, and then use another tool to produce the 4 quadrant.
Have a look to (free) PosteRazor application.
http://posterazor.sourceforge.net/
You can use the report generated by code, as available in our mORMot framework.
Each page is rendered in a TMetaFile content. In fact, you can use QuickReport or other report able to export the pages as meta files. The same occurs for charts: you save the chart as EMF content, then you draw it on the TGDIPages report.
Then it is easy to use a 2nd report instance to draw 4 pages per page.
Then you'll have preview, print or native pdf export at hand.
I saw this picture and now wondering if/how you can do this in Delphi. The highlighted/selected text shows two forms of formatting, i.e. highlight color and hash lines.

I've done something very similar recently in a bible application, also done in Delphi.
The user can select a single verse and single words of the selected verses. (But this feature is not released yet, so don't bother looking for it)
I used the web browser control from Microsoft and added my own kind of selection handling.
I've done the formatting by enclosing the relevant parts with span elements and changing their CSS style. When the selection gets removed, I also remove the enclosing elements.
The hard part was backing the "visual" selections with a selection data structure and handling all the selection events (clicking, shift-clicking, shift-ctrl-clicking, ...)
Embedding IE seems to be an easier way to do this as DR says, but you can also do this manually by drawing it all on a canvas, an easy way would be to create two bitmaps (one without a selection and another selected (could be as complicated as you like - dashed, colored, ... )), and you need to know the positions/rects of all your characters which would be somewhat difficult for long texts.
You basically show the unselected bitmap, and overlap the selected parts by portions of the second image.
You would also need to handle the selection manually by OnMouseDown, OnMouseMove, OnMouseUp...
