The bigest problem is the speed if IrregularGrid is true. I have posted many times regarding this issue and there seems to be no good answer. I have images with data that center around zero. In order to get negative numbers displayed I have to set the IrregularGrid property. This brings the plot spe...

Bitmaps to avi file

Has anyone ever requested or asked how to save plots (say line plots) generated with your tools to an avi file (or other movie file format)? Is there an easy way to do that?

There are many of these routines on the internet. I would suggest starting on the Numerical Recipes website. They have a few different interpolation routines.

Thanks for your response. I saw that example and have a couple of comments. 1. While that example is running, use the cursor and zoom in on an area. When youi do that, it stops updating. 2. In orde to speed the charting up, I would like to minimize the number of points in the chart. Is there an easy...

Tic Labeling Question

I am trying to develop a work around to the many problems with the TcolorGridSeries plot type. Specifically, because of the slow display update rate when IrregularGrid is set to true, I need to label the axis tics manually when ever they are drawn. Setting the labels manually using the following cod...

2D strip chart

Is there an built in way to implement 2 strip chart using the TColorGridSeries? I have a stream of data that I want to display column by column as a moving pixel plot. Is there an example of this?

How to add a default color palette

I am using the TColorGridSeries and would like to add a new/custom color palatte like the pre-defined ones. I have tried calling SetDefaultColorPalette like in the example code Custom Palettes but this does not seem to work. Can you tell me where in your code you define the defaults like Victorian o...

Thanks for your response.
- Is there a temporary work around for this issue?
- When do you expect to have it fixed?
- How long has this been an issue and do you think the fact that that the colors on a color plot don't match the values is a serious problem?

After further investigation, I believe that the tip tool is reporting the correct value, it is the color displayed for the pixel that is wrong. If you zoom way in, look at the value the tip tool returns the look at the legend. the pixel color does not match the value.

TMarksTipTool error

Have you noticed a problem when IrregularGrid is false the tip tool reports the wrong value on ColorLineSeries when zoomed? I am using a ColorLineSeries and when I zoom way in, it seems to be reporting the wrong value. When I have IrregularGrid = True, this does not seem to be an issue. Where in the...

I have been talking offline with Narcís on the TColorGridSeries speed issue while the forums were down. The slow speed is very obvious regardless of the number of points when IrregularGrid is set True. As you would expect, the more the points, the slower the plot. In the end, Narcís says that there ...

TColorGridSeries speed question.

I am using a TColorGridSeries to display images. When I put 500,000+ points in the series, it redraws EXTREMELY slow (for example, when the chart is resized, zoomed or a repaint is issued). I tried setting BufferedDisplay to false and this didn't really help. Is there anything I can do to speed this...

I do not seem to be able to get this to work. The Locate method seems to always return a -1. Even if I put a number I know is in the XValues array.

Are you sure this works with TColorGridSeries?
