New Improved Charting

Posting here after a long time. Mostly because I didn't feel like posting anything due to the downtrend in the markets. But now that things are improving, let me showcase the improvements I have made in the charts.
The chart has now 4 different panels. One for the master, one for the chart, one for news related to the stock being charted, one for portfolio pie-chart. I have also added user ID column everywhere so that others can add ther portfolios and track. But since its a client server thing only one of my colleagues uses it. Plan is to bring it on the web. Have started a small one, but its at a very nascent stage. You can check it out here.. http://rajarech.s43.eatj.com/MySite/showportfolio.jsp?UserID=mitra&Password=mitra
Basically there is a login screen which redirects to this screen based on the user Id. This page auto-refreshes every 1 minute so that you get the latest updated values. The colors of rows become red if today's growth for any particular stock is negative. You can also view charts. Right now have linked to the NSE charts because the free server where I am hosting this site allows me only 5MB space which is insufficient for storing my data and builing my chart.
On the client-server front, I have added several features since the last time I posted here. One can now view previous day (intra-day) charts, for both stocks as well as portfolios. Have added volumes which gives a much better picture of the movements now. In the chart you can see the bright line is for the price while the dark one is for the volumes. On mouse movement over the chart the price, date and volume are displayed on the 1st panel. Have also added the news panel in which I get latest news from moneycontrol and if any news matches the keywords specified for the stocks then the news item are displayed. The pie-chart shows the portfolio stocks at their bought value (outer circle) and current value (inner circle).
Thats all for now.
