When adding shapes (polygons) to the Map series (like in the example), when the form that contains the map is closed down, the memory is not released. Is there a proper way make sure that when a form is closed that memory associated with the Map and its shapes are cleared? Right now, I am doing this...

Hi Jon, I'd like to apologise if my explanations weren't clear enough. To explain it better I've made a small video showing where to find mentioned features demo an tutorials. This video uses TeeChart for .NET v3 as I don't have v2 installed at this machine at the moment. However, it is almost the ...

Hi Jon, Sorry if I wasn't clear enough. Actually this is an example of "DemoProject" but already compiled exe can be accessed from "Feature demo" shortcut at the program group created by the installer at Start Menu -> All Programs -> Steema TeeChart for .NET v2. Under the "TeeChart for .NET" folder...

Hi Jon, I'm not sure about what you are trying to achieve but you could either try using DrawLines tool or custom drawing on TeeChart's canvas. For DrawLine tool you'll find examples at All Features\Welcome !\Tools\Draw Lines in the features demo. I have TeeChart for .NET v2. I don't see any path t...

How can I draw simple line segments on a Map series?

I'm writing a PrintPage event handler and I'd like to call TeeChart to print a graph directly to the e->Graphics object or to a bitmap. Is that possible?

Hi Jon, Have you looked at the TeeChart help file available at TeeChart's program group? Also features demo and tutorials are provided. If this doesn't help don't hesitate to let us know. The TeeChart Programmer's Guide is a somewhat useful, but not very complete, help file. For instance, the Polyg...

I'm trying to figure out how to draw shapes/polygons in the map series. I've looked at the example (TeeSHP.cs), but that isn't getting me anywhere. The API documentation is fine, but it doesn't help at all when I am trying to understand the general approach. Is there not any documentation other than...

Is it possible to restrict the user from seeing - or at least editing - data in the chart editor at runtime?

Jon

In order to more quickly write up documentation for our application, I was wondering if there is any documentation or help files already available for *users* of the TChart in an application setting (i.e. not a developer)?

Jon

Hi Jon, Yes, this can only be achieved with TeeChart for .NET Professional versions as Lite versions doesn't include chart tools. The tool necessary for this is Drag Points tool. You'll find examples of its usage at All Features\Welcome!\Tools\Drag Point in the features demo. The demo can be found ...

In either the regular developer version or the Lite version of the tChart .NET component, can points shown on a graph be visually edited? For example, can a single point be selected and moved around with the trace line updating in realtime?

Jon

I have data that looks like this: -175 -170 5E-20 -170 -165 2.7972E-08 ... 175 180 5E-20 180 -175 5E-20 I've got this data plotted in a polar plot and it looks great, except that the angular labels that are placed about the circumference of the plot go from 0 to 360. I'd like the labels to go from -...

Hi Jon, I'm not able to reproduce this problem here. It is the first time I hear about a similar issue related to TeeChart. I reckon there's a problem with your hardware or its device driver. Have you been able to reproduce this problem in your machine? You could also try upgrading the device drive...

I have discovered a couple of things that seem to lead to a blue screen. 1) Place a TChart on a form. Add any random data series. Enlarge the size of the TChart object in the form, dragging the mouse just outside the form. Right click on the chart object and select Print Preview. After that dialog p...
