strange problem with teeCreateMetafile

Hello, I have a strange problem that is appearing. It only happens if I used a colorGrid with the rainbow palette. If I use my own palette it does not happen. Basically, when I render the TChart to a PDF file, I first use TeeCreateMetafile and then paint that metafile onto the PDF. For the type of p...

Hello Narcis, I found this demo a while ago, but it is not what I need. This changes the max-min range of the longer axis so that it is proportionally longer than the max-min range of the shorter axis. As a result , there are considerable blank areas on the plot. It would be fine for what I needed i...

I am a little confused as to one of the comments above. Marjan said you could use the onGetAxisLabel to customize the axis, including color etc. However, onGetAxisLabel only has a "var LabelText:string" to pass back the actual text. How would I use this method to customize the color?

We have recompiled with teeValueSingle and had no problems. The only thing to remember is the usual stuff, make sure that your project is pointing to the modified source, and not the old dcu's in the lib directly. The bpl's can usually stay the same, since they are usually used just to register TCha...

Do TeeCreateMetafile to get the metafile.

Then, do printer.canvas.stretchDraw(teeMeta,coords)

Where coords are the calculated coordinates in the printer resolution.

how do I know that the mouse is over a chart axis label

Hello,

I want to change the cursor if the mouse is over an axis title. Is there any way to check this in the onMouseMove?
