Axis Sections for Multiple panes

[User (Legacy)]

Hi,

I am using Axis sections to highlight portions of my chart. (I have attached 

the screenshot of the same).

I am having a chart with 2 panes shown one above another. Now to highlight a 

portion of the chart I am using 'Axis Sections'. The advantage being that it 

shows the corresponding selection in both the panes. However, I noticed the 

following problem:

1) The horizontal gridlines(Y axis gridlines) vanish/dissappear inside the 

'Axis section' area. This happens only for the upper pane. For the lower 

pane, notice in the screenshot that the gridline is visible even insde the 

axis section region.

2) For a normal single pane chart I found that that gridlines are visble 

even inside the axis section area.

Is there something worng in the way I am doing it?

Thanks,

Raj

This is a tricky one.

The behavior is caused by the order in which axes are drawn. The X-Axis is

drawn right after the first pane is drawn and therefore it cover everything

the Y-Axis drew. Other panes are drawn later, therefore anything they draw

(e.g gridlines) are drawn on top of the X-Axis.

The solution for you is to use Stripes instead of axis section. Stripes are 

drawn BEFORE all axes so all gridlines will be on top of them.

For example:

chart1.Stripes[0].From = 2;

chart1.Stripes[0].To = 4;

chart1.Stripes[0].Color = Color.Red;

chart1.Stripes[0].Axis = AxisItem.X;
