Hello,
We have a streaming HTML demo (HTTP Push Comet) that updates stock prices in a webpage in real-time. ? We want someone to update/redraw a chart on each stock price update received. ? We would like to do a demo of this in each of the charting frameworks:
1. RaphaelJS
2. Flot
3. amCharts
4. Emprise JS
All the streaming data and JavaScript to receive the stock prices will be provided - all you have to do is download, configure and write the code to make the charts update in real-time.
More details:
* Each chart should be on a separate HTML webpage.
* Each chart wll plot a single stock price.
* For all charts - the X-axis should be time (this data will not be provided - use the JavaScript Date object). ? The Y-axis should be the Last Price.
* Where possible avoid full redraws of the chart and use the chart API to update dynamically.
* The chart should update on each price update received from the Streaming Server (streaming details will be provided).
Look and feel:
* RaphaelJS: Use the "Raphael Analytics chart" as the basis.
* Flot: Use a simple line chart.
* Emprise JS:? Download the Personal Edition.? Use a line chart.?
* amCharts: Use the "Stock" chart on the frontpage. ? Use a candlestick plotting style (you may need to make up the Open,High,Low,Close data - just add/subtract random numbers to the LastPrice). No need for Volume or any other data.
Thanks,
