Updated Jul, 12:
a) New calculation algorithm from the book of Thomas J. Dorsey "POINT AND FIGURE CHARTING". As a result, both High and Low prices are taken into account during the calculation and the first bar detecting algo is much improved.
b) Width of each X or O bar can be specified in a number of price bars. The 0 value stretches X-O diagram to the width of the original chart, so, for example, you can see the whole source price as well as the whole X-O diagram in the convenient view.
c) The algo of updating of the chart when a new price bar appears is fixed, so the chart does not become broken anymore.
There is an implementation of the point and figure diagram, which, I hope, can be used until some default solution is implemented in the Marketscope.
The indicator shows colored bars instead of X and O's, but, as far as I can see is easy to read and to use.
To see the detailed information (when bar is started, how long is it, how much boxes does it contain) just move the cursor to the arrow at the beginning of the bar. The information will be show in the tooltip.

Also, please not forget that the time axis means nothing for the point and figure diagram. It is always shown ending at the most recent completely closed bar on the chart.
