OK, I have tested it and I do not think it works. Some comments... 1. In file TeeVideo.pas, procedure SetCompression after calling GetCompressors, you only compare the 1st 4 characters of the compressor strings returned to the value passed in. This will never result in a "True" comparrison if the wh...

Would it also be possible to import a AutoCAD drawing file and possibly display it in a series? I would like to overlay a line drawing on an image displayed on a TColorGridSeries.

This looks very promising! Is there a way make the bottom and left axis labels look like the ones you put on the right and top? Or, can I swap them and hide the right and top? Meaning if I put my values into the top and right and do what you did for the bottom and left. It all looks great if I hide ...

Outstanding!

I dont know why I wasn't able to do what you did with the top and bottom axis. That is all I really need to do with the bottom and left.

I will continue to look at what you sent, but it looks really good.

Thank you very much for your support.

I have recieved your code changes and looked at them. I think maybe I have not made my problem understood. What I am doing is generating an image of a target and measuring the distance of its features in feet from the center. That is why I need to change the axis values to make zero at the center. O...

Thank you for your quick response. You are correct, RTInumbers do NOT have an impact on this issue. I tried to remove unnecessary code when I cut and pasted from a larger project. I just missed that one. Your explaination is very clear. I will give it a try and let you know how it goes. Thanks again!

Hello, it has bee a while. I am still unable to translate point values from the axis labels I created to pixel values on the screen so I can re-draw my polygons. I have posted a simplified example on the upload page link you supplied earlied in this thread. It is called "Image Test 2.zip". There are...

Your last answer is what I suspected. And, I agree that an "in-chart" solution to calculate the nearest axis Label index (or value) from an x,y point is a necessary function due to the inefficiencies of the chart when IrregularGrid is true. Also, given an axis label value, calculating the nearest x,...

I want to be sure that I understand exactly what you are saying. I agree that CalcPosPoint is returning the axis values I put in using the Chart1.Series[index].AddXYZ method. Using that method because I have IrregularGrid set to false, I just increment a counter for the X and Z values. So, CalcPosPo...

Sorry to be a bother, I know you are busy. But did you receive the example code that I posted for you? Can you rebuild it and is it self explanitory enough?

Thanks

OK, I sent a zip file with sample code to your upload site called "Image Test.zip".

I build this with Delphi 2006.

Let me know if you have any questions...

Thanks!

Yes, I will try to, but it is quite a lot of code... It seems that the disconnect is between the values I load into the axis using: Chart1.Series[SIndex].AddXYZ(i+1, DblImageData[i,j], j+1) and the values I load into the x axis labels using: Chart1.Axes.Bottom.Items.add(i,Format('%-.2f',[x])) The co...
