overrided method to update series id and order id

I can see these methods, but your comment does not help to understand what problem they were supposed to solve in the first place.

I first of all question their public visibility. Since I don't think it is good practice to rely on the developer using the library to know when to use and what to expect from them...

so we created update methods, because in a chart, we need to provide unique value to each series, now while creating combo chart, i.e. line series and bar series in that case we assigning same values to each series due to that it was corrupting the office file. Now either we can create a new constructor with new parameter i.e. index or can provide an update method to re-assign axis id and order id. so i chose update method.

I finally understood what you were trying to achieve! I had a similar code in a PR that I left aside because of some more changes required after a comment about API requiring changes.

https://github.com/apache/poi/pull/139/files#diff-17a515ee7210ab25ee2bcedbf5e49a87R116

I also tried to get all series list in chart data, but as there is no relationship between different series types, so we are left with only series list of particular chart data.

Your updateXXXVal() methods are disguised setters. I am not quite sure this is the best way to achieve your goal (which I still does not understand at this point).

so we created update methods, because in a chart, we need to provide unique value to each series, now while creating combo chart, i.e. line series and bar series in that case we assigning same values to each series due to that it was corrupting the office file. Now either we can create a new constructor with new parameter i.e. index or can provide an update method to re-assign axis id and order id. so i chose update method.

The three lines above don't follow formatting rules for the project...

And the pattern is (wrongly) repeated until the end of this class!

Despite being internally represented as an int value, the rotation represents an angle which developers using this library will expect to be expressed in degrees instead of the scaled range allowed by the specs.

We will have to provide a converting mechanism. I am sorry I got it wrong in the first place on the other properties representing angles...

yes we need to write a utility method for conversion.

i am writing that utility method. so if it's completed early so i will check in that code with this pull request.

While reading the specs, this is one of the few places where the angles are given as integer values, without scaling by 60,000 to get more precision.

As matter of facts, all the methods names have to be adapted to the conventions used otherwise in the project:

no Val suffix

no unpronounceable name such as RAngAx

no shortcut as RotX, RotY or HPercent but RotationX, RotationY and HeightPercent

updated method names.
