I have added a few TeeChart objects to my application and populate them from ClientDataSets. They seem to work as expected, but when I close my app, either as the compiled program, or while running in Delphi 7, I get a lot of memory errors that pop up. They don't seem to be the same error, and I hav...

Is there a way to force the offset of the left axis title from the left axis scale? I am finding that my title partially overlaps the scale values when I save as a pdf. It works fine in normal printing and print preview. It only becomes a problem when I save to PDF. If I set the format of the scale ...

Perfect!

Why does my VCL 7.07 TeeChart have design time PDF as an export option, but at runtime, it is no longer available?

I think part of my problem is my lack of understanding of [ValueIndex]. My point style is determined by a string value that is not part of the XY data set. The Detected column is evaluated as the program steps through a ClientData set. For instance: X Values.....Y Values......Detected......Point Sty...

I have reviewed and implemented the code you suggested, but when I try it, the Chart always changes the pointer style for the entire series, not individual points.

In my line series chart, I want to be able to change individual pointer styles along a line. I am charting analytical results and I want to be able to let my users know when a value is an actual result, and when the value represents a detection limit. For instance the value 100 would have a psCircle...

I got some advice from a friend of mine...

When I replaced all the references like

"dm.qryLResultSample_NAME.AsString"

with

"FindField('SAMPLE_NAME').asString"

it worked great!

I know these columns of data will exist at run time, because the dynamic query in my code is set to run a specific list of key columns. The "catch" is assigning these columns to TeeChart at design time so I can compile the program. It appears that if I instantiate one column, I have to instantiate t...

This is the piece of code that gives me a problem: with dm.qryLResults do begin DisableControls; try First; while not(EOF) do Begin if dm.qryLResultsSAMPLE_NAME.AsString = SampleName then if dm.qryLResultsANALYTE.AsString = AnalyteName then begin SampleSeries.AddXY(dm.qryLResultsSAMPLE_DATE.AsDateTi...

I am having great success getting TeeChart to cooperate, but now have problem I need some help with. I have a dynamic query that can result in a variety of columns using my Delphi 7 app. I don't instantiate the fields in the datamodule, to allow it to accept a variety of columns. If I instantiate th...

Sorry.... We do environemtnal projects that commonly involve the work of 2 or more entities (us, our clients, laboratories, etc.). We have developed a Delphi app that allows all of us to share all this data. In this case we are cooperatively developing schedules. For instance our client may schedule...

My users currently use the Gantt chart to communicate scheduling information in a Delphi (7) application. The information is provided through a scan of a data table that they can modify. Is it possible to use the TCalendar in a similar fashion so that they can more easily see the day of the week, etc.

Is it possible to assign a bitmap to a 3D Wall that can then be rotated in 3D space? I have tried assigning an image to a wall, put it appears to be just a transparent window to a bitmap behind the chart canvas.

Marjan,

I got your example code to work! You suggestion of using the cube is a better approach.

Now, how do I get multiple cubes to show up? I have made line graphs using AddXY to a series. I think I want to have each cube be it's own Series that's color is based on concentration.

Thanks
Craig
