Subject: Need help with charting functions

I am evaluating the chart program and need some help while I evaluate if
this will suffice my project.
1. Is there a way for me to call classes as a script of some kind to do the
calculations for me on the front end for the graphs.
2. I need to make my own technical indicators for a stock program I am
writing and I need to know how the methodology works on your charting
platform. Can I create my own functions? How do I go about doing that within
your charts as I don't see a way off hand on doing that. I need to know how
to write my own function and call them from the charts.
3. The reason I am asking about a function instead of going straight to the
database is due to the fact that I want the database to store data. I am
worried about the transaction logs and performance on the database side of
things. I want the front end to do the calculations.
4. Can I stack the indicators below the main chart one at a time and put a
limit on the amount of smaller charts below? Basically, for every indicator
chosen by a user then a new chart (very small) is stacked below the main
chart?
5. I noticed a problem on the charting within Delphi. If I create a pop menu
with a submenu and call the series within the code to ChangeAllSeriesType(
Chart1, TBarSeries ); on different submenus then it will fail. It will work
once and then it gets corrupt. Let me explain in more detail. Lets say I
have a pop menu with 4 submenus named line chart, darvas chart, area chart
and renko chart. Then you do the unusual double click each on and put in the
code for each submenu routine of "ChangeAllSeriesType( Chart1,
Tlineseries );"and so on for each one. It compiles just fine, but when in
runtime if you go and select the different chart series you want laid out it
will stop charting. I think the reason why is by default the chart is done
with a check box series and not a radio. So when I am selecting different
charts its just trying to overlay them. Do you have a solution as to how to
get this done?


Thank You for in advanced for replying. I am trying out your product and
need to make sure it does what I want it to do before I purchase it.

Thank You!
