Bug in SeriesBand

[JosefG]

Hi,
I have send these requests one year ago:

1) TSeriesBandTool should respect the property "stairs" of the associated series'

2) TSeriesBandTool should have two colors:
Color 1: where Series 1 > Series 2
Color 2: where Series 1 < Series 2

This was your answer:
1) You are right. I've added the bug to the wish list to be fixed in future releases (TV52013891).
2) Thanks for the suggestion. We'll try to implement this in further releases (TV52013892)

Now I have tested version 2010 Beta and found no improvement in this issue.

I'm a bit disappointed about this, because it really would be important for us.

Regards,
Josef

Hi Josef,

Thanks for your feedback.

1) TSeriesBandTool should respect the property "stairs" of the associated series'

I'm afraid it would be difficult to implement TV52013891 because TSeriesBandTool is "series style agnostic". It is designed to work with most series styles. Therefore, since many series styles don't have the Stairs property, it can not be used inside tools plotting routines. To implement this a complete redesign of the tool would be necessary or even an specific tool for staired series.

2) TSeriesBandTool should have two colors:
Color 1: where Series 1 > Series 2
Color 2: where Series 1 < Series 2

Regarding TV52013892, currently TSeriesBandTool uses one polygon for plotting the entire area. Implementing this would mean using 2 polygons, one for each color. Anyway, I have incremented its priority on the list.

Luckily I was wrong . I have finished implementing this feature in TeeChart Pro 2010 VCL. We should run some more testing but it was much easier than I expected.

This is great!!!

Maybe even second request (the two colors) is doable in the near future.

Hi,

again, this is an importand improvement for us. Thank you.

Also the above chart shows, that it would be very desirable if the color would change if the value of series2 is greater than the values of series1.

Hi Josef,

Yes, we'll also try to implement it for the future releases.
