LegendScrollBar Tool

Alessandro · Post by **Alessandro** » Tue Oct 25, 2005 10:16 am

Hi,
Legend scrollbar tools have some strange behaviors:

1. Scrollbar share the same space of the legend, so series names do not appear completely.

2. If I chart a lot of series, then scroll down, and then remove most of the series, scroll position is not reset in any way, so if you have that your first visible series in the legend box is not in the chart anymore, you cannot see the legend, and just a long scrollbar remain on screen. If you scroll this scrollbar up enough you'll get your legend back.

3. If using also LegendCheckBoxes (since legend and scrollbar share the same space I suppose), everytime you try a scroll operation, either by clicking or by dragging, the nearest series checkbox is triggered.

4. WhenNeeded Draw style works really strange: scrollbar is shown even if all the series are displayed in the legend, but sometimes when scrolling disappear... If you keep dragging and return to the previous position you get your scrollbar back, but if you drop, bar is lost.

5. Problem n° 2 combined with Problem n° 4 makes legend disappear at all...

Hope I'm doing something wrong.

Bye,
Alessandro

Hi Alessandro,

Thanks for reporting those issues.

1. Scrollbar share the same space of the legend, so series names do not appear completely.

I've been able to reproduce it and have added the defect (TF02011049) to the bug list to be fixed for future releases.

2. If I chart a lot of series, then scroll down, and then remove most of the series, scroll position is not reset in any way, so if you have that your first visible series in the legend box is not in the chart anymore, you cannot see the legend, and just a long scrollbar remain on screen. If you scroll this scrollbar up enough you'll get your legend back.

I've also reproduced and added this to the list (TF02011050).

3. If using also LegendCheckBoxes (since legend and scrollbar share the same space I suppose), everytime you try a scroll operation, either by clicking or by dragging, the nearest series checkbox is triggered.

Also reproduceable and its item number on our defect list is TF02011052.

4. WhenNeeded Draw style works really strange: scrollbar is shown even if all the series are displayed in the legend, but sometimes when scrolling disappear... If you keep dragging and return to the previous position you get your scrollbar back, but if you drop, bar is lost.

I haven't been able to reproduce it using latest Debug Build version available. However, when testing that I noticed that when using:

legendScrollBar1.DrawStyle=Steema.TeeChart.Tools.ScrollBarDrawStyle.WhenNeeded;

LegendScrollBar is disabled but displayed, which is already a bug that I've added to the defect list (TF02011053).

5. Problem n° 2 combined with Problem n° 4 makes legend disappear at all...

I've also been able to reproduce it and its defect number is TV52011056.

We will try to fix those issues for our next releases.

Hi Alessandro,

Our release policy, approximatelly, consists of 3 maintenance releases and one major release every year. According to this you may expect one release every 3-4 months. Considering that last maintenance release is from 2nd August 2005 a new maintenance release should be out soon. However, I can't still give you a date when will it be out.

To reduce the waiting time for our customers, we started the Debug Build Initiative. So you may want check those versions periodically.
