Hi, One of the TeeChart licenses that I purchased a few of years ago was used to develop a product featuring a web-based UI. In that product, Teechart ActiveX charts are instantiated as ActiveX objects in HTML/PHP pages. This product falls in the “Applied Web browser scenario” of your licensing web ...

Sandra, Thanks for your reply. I hadn't seen the Axis tab in the tools section ;-) The AxisArrow tool is what I need but it doesn't seem flexible enough in my case :-( : - It's drawn on a vertical plan. I need it drawn on the horizontal plan (bottom axis). - It doesn't follow the ZPosition setting o...

version: 3.5.3425.20245 Hi All, My chart displays a tower series that looks like this . A rotation tool is used to allow user other view angles. The problem is that once the chart has been rotated, user is a bit-disoriented. To fix this, I'd like to draw an axis with an arrowhead, like this . If thi...

Narcís, Thanks for your reply. Regarding the video, the app does more than that: It captures and combine the input from 2 cameras (720x576 pixels each) + sound from a microphone. It also collects data from a measurement equipment. It adds various texts and drawing to each video frame (including a co...

Narcís, I'm afraid I don't get you!? :( In my case, performance is an issue. And clearly, 100msec to take a copy of a bitmap is not acceptable. Let me re-state my requirements: - The program continously fills in the tower chart with real time data (1 point added or modified every 100 msec). - Every ...

Env.: VS2008 / .NET 2.0 / C# / TChart 3.5.3330.21114 Hi, I have 3D tower chart that continuously receives new points. I need to periodically (every 1 second) take a copy of the chart image (in memory) to asynchronously display it elsewhere in my app. It must be fast because I'm also displaying live ...

Thanks Yeray!

Hi, I have a bargraph with marks above each bar to display the value. If the value is 78, I want to display 78 %. If I simply add a % in ValueFormat, it turns to 7800 % ! I noticed that I can avoid this 100 factor by using ValueFormat = ##0 '% (note the ' before %). Is this the recommended way to to...

Hi, I have a 3D tower series whose roughly looks like a 3D circular Gauss curve, if you see what I mean (X,Z values are inside a circle centered on 0,0. Y values are >=0. The highest Y values are in the middle of the circle). I know the range of values for X,Z hence can set scale on bottom and depth...

Thanks Narcís.
I hoped for a solution based on the functions.
Anyway, this one is less elegant yet very efficient

Yeray, I'm not quite sure what the outcome of your logic would achieve. Especially since MouseDown comes before Zoom, UndoneZoom et al. Anyway, I found a solution based on the fact that MouseUp() is synchronous with Zoomed() and UndoneZoom() (fired during same WM_LBUTTONUP message) and fires *AFTER*...

v 3.5.3225.32185 / VS 2008 / .NET 2.0 Hi, First, I'm trying to have a series which draws a flat lineshowing the max value of a series. Easy: Use the high function. Data source = the series. Function period = 0. Works fine. Now, I want the same (one) flat line to show the max value of all points in 2...

Env.: VS2008 / Vista / .NET 2.0 / TChart 3.5.3274.30664 Hi, My chart support zooming + a cursor tool. When user clicks the chart, I set the cursor tool position at the mouse position. I initially handled the click in the ClickBaground() event. But it appears that when this event is subscribed, mouse...

Seems to work. Great!
Thanks for your help.

Hi Narcís, I've upgraded to the latest version. It does indeed seem to solve the problem for the test project but the problem still occurs in my real project where there are more points. I'll do my best to reproduce the problem in the test project. In the mean time, here's the call stack when the pr...
