Description James Moody

In my report I have axis chart A followed underneath by axis chart B. A general statement of the problem is that I would like the X axis of chart A to align with the X axis of chart B. Currently this is not possible, because even if I make the charts the same size, differences in y axis labels and potentially differences in legend text (if I have the legend on the right) mean that the plot areas end up being different sizes.

I'd like a layout setting that would let multiple charts, laid out vertically, to have X axes that line up. (I suppose, for completeness, if I had multiple charts, laid out horizontally, I'd also like to be able to have the Y axes line up).

Please see the attachment for an example of the problem today.

How about letting chart designer to specify a fix width for the Y axis data point labels region?  Then either wrap the labels, or clip them to fit into the fix width?  


Also allow fix height for the X axis labels region?

1. Added a new double property named LabelThickness to the model of Axis, which gives the user a way to indicate a fixed thickness of axis label. Hereby label thickness means width for vertical axis and height for horizontal axis. 

2. Added the UI to modify this property in axis format page.

Now the user has the change to align axis of multiple charts, if they have the same fixed labelThickness of axis and all related settings are the same, especially for the axis title. The user should also be responsible for selecting a reasonable value for LabelThickness, a too great or too small LabelThickness can cause the axis label to be dropped all overlapped with axis title.

So this is a simple and limited solution for this use case, if the user use it properly the requirement can be fulfilled.  Anyway this is not a very common use case, in general we will not exchange informations between separate charts.  There is also a similar use case in bugzilla #170985, maybe it's also interesting for you.

Verified on build 2.5.0 v20090309-0630.User can set the Label Span to control the space for the axis labels. It's a workaround to align the axis of two charts when other settings like the axis tile are the same.
