hi
is it possible to add 2 Y-axis for each segment in stacked view? (like componentone for example, there is a Y2 property)
I would like to stack wave files and add a trendline in each of them with a different scaling (for example the RMS value in dB),
but I want to use only one chart to zoom over all the segments.
thanks

It's currently not possible. Each stack segment can hold only one axis.
Create two charts, set 2 Y axes in each, that's the only solution...

hi

like I said I want to use only one chart to zoom over all the segments.

It could be possible if you add a layout for the X-Axis

axislayout.XAxisLayout = stacked
axislayout.YAxisLayout = stacked
axislayout.XAxisAutoPlacement = Allbottom
axislayout.YAxisAutoPlacement = LeftThenright

Is it possible to add this feature ?

thanks

you can see an example

Thanks, we'll think about it. The Y axis count per segment should be unlimited.

hi

i'm ready to buy a license every year for my project
but I need this feature, is it possible to add it ?
I think is very useful.

thanks

Send Purchase Order, and put this feature in the as Condition to purchase order. Allow us 2 months to complete this modification. It's far more complex than first thought, because of real-time optimizations we have there.

ok but how it works ?

Ok, we can assign the condition here. Just order it and I'll set it to quick implementation queue.

ok thanks
I will buy it next week.
I want to test a few things before.
Maybe Tuesday or Wednesday.

ok it's done, I bought a license.

Like you said, can you set my requirements to quick implementation queue ?

What I need :

1- Two Y-Axis per segment (left & right) for 2 sampledataseries (see above)

2- An property to show panning icon after the threshold
(ex: ZoomPanOptions.ShowPanningIconAfterThreshold=True)

3.1- Can customize segment (color, grid, ...)
3.2- And add events to each segment (MouseDown, MouseUp....)

Tell me if it's okay for you
Thanks

We haven't still received the order from Share-it, the payment is probably in pending state.

About your conditions:
1. We agreed only 1 inclusive. By itself, it is a major task for us.

2. We can add pan icon threshold as well because it is a small task.

3.1 - 3.2 we'll have to reject these. You can use LineCollections for grids, and use chart.MouseUp/Down/Move event handlers, and compare the coordinate to segment coordinates.

ok

payment done!
thanks

The segments controlling is now available in 6.3.1 version.

yesss
I will check your new version
thanks

hi

very good job for your segmented view, very easy to implement.

but the getgraphsegmentinfo function doesn't return the good information when the layout is set to segmented

example :

Chart.ViewXY.AxisLayout.Segments.Count = 2
Chart.ViewXY.GetGraphSegmentInfo.SegmentCount = 1

It's a little bit disturbing.

it would be nice if you can adjust the second function if you have a segmented view.
otherwise, we must add a lot of "if" to check the layout.
Or you can combine both functions into one function.

thanks

and how you can get the segment height (in pixel) ?
like chart.ViewXY.GetGraphSegmentInfo.SegmentHeight

because chart.ViewXY.AxisLayout.Segments(i).height return always 1

thanks
