TeeChart & RBuilder

rbuser

Hi All

I've added TDBChart (ppDPTeeChart) to my report (in the Detail section),
connected it to DataPipeline, set the "Point per page" to 15, and run the
report, but the chart kept showing the first 15 points without changing
values. What is that I'm missing ?


Thanks
Ofer

I have worked with TppTeeChart quite a bit, but I am not familiar with the
"Point per page" property. What object does this belong to?

Open the Chart Editor and select the "Paging" tab.
The question is how did you make the TChart & RBuilder work together in case
you have 300 points to show and you want to show only 15 points on a chart,
which lead me to a thought to put the TChart in the detail section, and to
connect the Report's pipeline and the Chart's pipeline to then same
DataPipeline ?
BTW, I couldn't find any Demo for this kind of report

If you take a look at the example that supplied with the "demo" application
you will see the similar problem. The chart has lables like:
HGJ, IFT, LN and many more (all values above "CTT" alphabetically) are NOT
in the legend. The Chart's height is too small to show all those values. The
chart should be at the detail section with limited number of points.

chart,

I would not connect the chart and the report to the same pipeline. Not sure
what issues this will cause, but I have always stayed away from it (both
will want to traverse the same data).

The


The "Points Per Page" does limit the values shown as it should. It does not
mean that if you have 100 points and 10 points/page, that it will give you
10 charts. Play with the TChart outside of RB and see how it works--it lets
you scroll the chart, which is not an option in a report.

You need to do the logic youself if you want limit the number of points per
page and have multiple charts. This is not done automatically.

When you play with the TChart outside of RB, you have the option to use
TChart's pagenavigator component. I assumed this is a built in feautre in
the RB.
The problem with "You need to do the logic youself..." is that this is not
easy to achieve, when you have a lot of rows from dataset, and the user move
forward\backward in the report's pages.

RB uses TChart to create a graphic that it shows in the report. The report
does not contain the component itself.
