When I open the test document and try to change the legend font properties (in chart edit mode) the legend position is also changes when closing Legend dialog (legend is repositioned to the left side of the chart area).

Steps to Reproduce:
1. Open attached test document
2. Double click on chart -> enter into edit mode
3. Double click on legend -> Legend dialog is opened
4. Change font type on Font tab page
-> Font type changes, but Legend also moves to the left.

Actual Results:  
Legend position changes when I set a new font type.

Expected Results:
Legend position should not change.

Reproducible: Always

provide two LegendPositionResources for the interim
LegendPositionResources for .ui based stuff and a legacy

Let's turn this into a easy hack. The code is here:
chart2/uiconfig/ui/tp_LegendPosition.ui -> defines the structure of the font page
chart2/source/controller/dialogs/res_LegendPosition.cxx -> implementation of the font page

Hello, I want to work on this easyhack. A little help will be really appreciated.

First of all, if you are working on a bug, set Assigne field to your email address and also change Status field to ASSIGNED. So others can recognize easily that somebody is working on this issue.

Now, about the code. Most dialogs get their input from an SfxItemSet container and also write their output back to this item set. When the dialog opens the settings are loaded from this SfxItemSet in LegendPositionResources::initFromItemSet(). When the dialog is closed the itemset is updated by LegendPositionResources::writeToItemSet() method. So you need to check what happens in these two methods. The expected behavior is that the legend position properties does not change if the user does not change them in the dialog.

May I know what is the use of "chart2/uiconfig/ui/tp_LegendPosition.ui"?

The *.ui files describe the view of the the dialog. This file contains the GUI elements what the dialog has and also position, size and other informations. When you need to define the behavior of the dialog you can do that in the *.cxx file and you can get a GUI element defined in *ui. with the get function (e.g. "rParent.get(m_pRbtLeft, "left");").
