Great is see some improvement in the game statistics.
However its graph form i'm not familiar with
Someone care to explain it, and enlighten me ?

THERE ARE 2 GRAPHS==A PIE SHAPED GRAPH THAT SHOWS THE PERCENTAGE OF WINS, LOSS, AND DRAW========A LINE GRAPH WHJCH IS A HISTORCAL GRAPH THAT SHOWS YOUR STATS OVER A PERIOD OFTIME.

The tactics graph is a candlestick graph. Each "bar" represents 4 different values. Your high rating, low rating, open rating and close rating.

If you want more information on this type of chart, please see this wiki article: http://en.wikipedia.org/wiki/Candlestick_chart

This feature is extremely cool, thanks for implementing that!

thanks for the wiki link jon

Hmm, shouldn't the open value of day x not be the same as the close value of day x-1?

I'll try to rephrase my question:

The blue bar is intended to show improvement. Is it meant to show improvement compared to

a) the closure rating of the previous day?

b) the opening rating of the current day?

At the moment it compares to the opening rating of the current day. So in fact it is possible to get a blue bar with a lower rating than the day before.

Doesn't seem right to me.

The past two days, I've done my 3 daily tactics and gotten them all correct. 

The Open and Low for June 7th shows as 1549.  The High and Close for that day show as 1570.

Then on June 8th, the Open and Low both show as 1582 ?  High and Close show as 1600.

If I ended June 7th at 1570, why did I start out at 1582 on the 8th?  What happened that I gained 12 rating points?

To me, it seems logical that my "close" from one day should be the "open" for the next day.  But that doesn't happen.

There also used to be a very simple (text only) thing that told you your current rating and your highest rating.  I liked that feature, and it went away.

Hi Baldr,

it shows your open rating on June 8th after the first (in this case correct) tactics on that day. It is not the close rating of the previous day.

Doesn't seem logical to me either ;-(((

From the wiki page:

A candlestick chart is a style of bar-chart used primarily to describe price movements of a security, derivative, or currency over time.

Because I want my experience on chess.com to feel like Wall Street.  Gee, that's fun.

"Because I want my experience on chess.com to feel like Wall Street.  Gee, that's fun."

The alternative is a line chart, which is also widely used in stocks. A candlestick chart is used in a variety of time scale sceneraios where a close, open, high and low can be used. It only relates to those because they are widely used in those.

"If I ended June 7th at 1570, why did I start out at 1582 on the 8th?  What happened that I gained 12 rating points?"

Currently, if you haven't done a tactic for today, the first time you complete a problem, the rating you acheive for that problem will be todays open rating. The time scale for a "bar" doesn't reflect data in the past. So by the use-case you provided, the first problem you did was a "pass" and provided you with an increase in rating, and thus, showed up as your "open" rating.

Your "start" and "open" rating are two different things.

So, if you left the day at 1570, and opened up with 1582 the next - that means the first time you registered a stat that day opened at "1582". 

Thanks for taking the time to respond, Jon.  Had I known I'd get a response, I'd not have been so flip.  But it seems that both graphs are now available, so my appreciation for that.  I actually like having the candlestick chart as a secondary graph.
